TYPESETTING CSS

Introduction

The first decades following the introduction of movable type in Europe saw printers facing problems in

translating (handwritten) manuscripts into textual layouts using metal blocks. The rapid growth of printed

materials and the introduction of more complex textual compositions required the printers to develop new

ways in which information could be more clearly represented. This led to the column-based layout, and an

ongoing standardization process. The work of the typesetter, particularly in the years proceeding to theintroduction of more affordable printing (the 19th Century) is well documented and offers a very useful set

of skills that can be easily manifested online using CSS and correct mark-up.

As Ruder1 observes, the typographer solves a very physical problem, lining up black and white shapes to

form words technique, function and formal design are inseparable part of the typographers work. The

fascination with the form of the written word was nothing new however it was only with the widespread

development of letterpress that the typographer role was born(and has been growing in prominence

since). The need to standardise the setting of type resulted in a set of rules and conventions most of

which are both accessible and useful when measured against the work of typesetting for screen.

Welldesigned works of print demonstrate perfect balance between word and typographical form. By

following the same conventions from books extraced bellow typographers could create harmonious works

that exceeded their primary role of transferring information. # We will scan through typesetting

resources in order to compile a list of guidelines and rules that can then be measured against its digital

equivalent by doing so a connection will emerge that will prove the relevance of the first to the latter.

Macro Visual OrderText must be broken up to manageable chunks so that the reader can follow it comfortably. The most

common way of separating body text is to break up ideas using paragraphs. To indicate a new paragraph

the typesetter can use an indent, a space at the beginning of a sentence, or a line break.

It is not advisable to indent the first line of the page, especially if it follows a header.

It is important not to join both methods of paragraph indication, that is to say that when you use a

line break, an indent is redundant.

The width of an indent can range from 1 to 3 ems and it depends greatly on the width of the

columns it is used in.

Swann2 compiled a conciseguide to typesetting and layout design in the later part of the 60s when a shift

from manual work to computer-assisted-technologies took place.

Line of body text should contain between 10-12 words

Words set in both capitals and small caps should be letter-spaced.

Small caps is generally a better option of emphasised text within a copy

Punctuation

The use of punctuation should be kept to a minimum and only be applied when it contributes to the

understanding of the text:

Full points are not necessary after well-known abbreviations such as Mr, Mrs

In abbreviated qualifications the last full point will be omitted, i.e. M.S.I.A

Full points in abbreviations may be excluded entirely where qualifications are not likely to be

confused e.g. Dr instead of Dr.

Single quotation marks are sufficient to indicate speech or cited text

Where cited text is italic or in smaller size quotation marks are not necessary at all

Instead of em dash3 () the en dash4() needs to be used followed by a word space

Leadins

Another way of indicating a new paragraph is setting the first word, or number of, in bold, italic, all caps or

small caps this technique is called Leadins. Other subhead include the hanging subhead, which is

essentially a subhead indented to the left. The amount of the indent will still be a result of the width of thecolumn.

Citation

When body text includes lengthy quotations and cited text (for example in some academic material) these

should be set in smaller point size, with less leading and across a narrower column, separated with a line

break before and after the text. These are often referred to as extracts. As the text is set to contrast the

body text by size and visual rhythm there is no need to use quotations. Indent is not necessary in the

extract nor in the beginning of the paragraph to follow as the text is already visually differentiated from thebody text and the paragraphs surrounding it.

Forms

Strictly speaking a form is a document with blank spaces designated for the insertion and collection of

data. The forms biggest goal as well as difficulty is to convey data clearly and collect data in a consistent

and accessible manner.

A well-designed form will keep consistent relationship between the information and the blank

spaces where information needs to be populated.

It is important to keep the boxed elements on an harmonic grid, and the visual noise to aminimum.

Typeface should be visually pleasant, anything between 11 to 14 points, with 12 being the ideal

size (though this may vary).

Information hierarchy is of the highest importance in forms yet mustnt clutter it, simple bold

would be sufficient to indicate areas requiring bigger attention.

Orphans and Widows

The typesetter has the freedom to advice changes to the copy that would enhance the visual consistency

of the end result.

A paragraph mustnt end with one syllable of a word this type of composition is known to be

very unpleasant to read (and is referred to as an orphan).

A page should not contain only one line (that is referred to as a widow).

Spacing

According to Jahn5 , spacing and justification are the two most important factors when setting type. It is

advisable to insist on close spacing even in the price of breaking a word in the end of the line. Much of

the common mistakes of spacing are a direct result of too large of type, without the appropriate

amendments to the spacing. Every size of type has recommended spacing, which will ensure both

pleasant typography as well as maximum legibility.

Figure 2.1.9 A - Upper-case word with additional letterspacing added (Swann,1969, p.35)

Steer6 recommends wordspace of one and a half to two times the linear (X) width of the lower-case

alphabet of type selected. Too much spacing between words mars the looks of otherwise coherent piece

of print. When word-spacing exceeds the correct measure, light is let in where it is not wanted, and the

wide rivers of white space distract the reader and make reading difficult.

Figure 2.1.9 B - Upper-case word with no additional letter-spacing (Swann,1969, p.34)

Spacing Terms

The Em space is a square unit of vertical body point size

En is exact half of that, three thick units are equal to one En, four Mid units equal to one em and

and five Thins equal to one Em.

The hair space is meant to be exactly twelve to the Em but realistically it come in various sizes

and can anything between 1 to 3 pt.

Corrent spacing is a tool typographers can use to align text harmonically and to avoid orphans, widows,

hyphenation and generally non-pleasant setting of type. As such this was considered to be a skill the

typographer would need to master, a process that would often involve very meticulous work.

the proportion of spacing between letters and words is not linear as the size of the typeface

increases and thus the typographer will need to consider the typeface against the neededspacing and maximising the legibility of the text.

commas and full point are equivalent to a word-space

The spacing of letters is also a tool typographers can utilise to increase the contrast of a certain word . It

can generate emphasize, distinguish as well as separate certain words. When letter spacing is used,

spacing bigger than a hair space is often used as mechanically its very thin and tends to break when

places between letters. Letter spacing was more commonly used when setting words in capitals and

small caps. Letter spacing should be dealt with caution, as appearance of some typefaces can be ruined

by excessive spacing. Even when separating display text it is important to be aware of the subtleties of

the typeface and examine the ratio between the white and black space.

Leading

Line-spacing, also known as leading is an important element that determines the readability of body text

and can be controlled by the typographer in order to balance long lines of text or typeface printed in less

than legible colour.

The longer the line, the more leading is needs

The lighter a typeface is, the more leading it needs to be kept legible

The leading required to keep composition pleasant is determined by both the outer space of the lines as

well as the internal white space within letters. Addiontionally, leading is often used as a way to control thecolour of the text. The smaller the text, the less leading it needs and the actual colour of the composition

is darker. When increasing the leading more light is reflected by the paper.

Justification

The alignment of the lines can have values of right, left or justified (which means that lines start and finish

at the same place). In order to control the alignment of the words at the end the line word spacing is often

manipulated. This creates gaps and irregular spacing, and thus a solution many typesetters prefer to

avoid, relying on other tools e.g. alternating body size, page margins or hyphenation.

7/17

Breaks

Word break refers to a situation where a word is broken by hyphen (at the end of a line). Hochuli7 points

out there should never be more than 3 successive word-breaks under each other.

Extra Dynamic Expression Of Order

Steer8 examines the notion of order through symmetry and breaking of it.

the readers eye mustnt come to a point of rest until the transfer of the message has been

completed in full.

the vertical grid as the major generator of dynamic order and keeper of the symmetry

the horizontal line is a suggestive tool and a visual break whilst a vertical one performs the

opposite role and encourages the reader to read through, pacing him though the text.

in vertical text we give prominence to the vertical dimension using visual queues and long and

narrow proportions. Dynamic layout uses geometric principles to visually secure elements into a

vertical order.

the typesetter ought to note the danger of creating a rigid and characterless layout and should

examine each piece of layout against its desired function.

it is the work of the typographer to create visual queues that demonstrate both order as well as

lack of it where appropriate. A design too harmonious might look monotonic and one with too

much flair will look chaotic.

Mechanism Of Reading

As the experienced reader tracks though the letters and words, their eyes jump across the lines. These

brief movements are known as saccades and their duration varies between 0.2 0.4 seconds. A line is

perceived in a series of saccades followed by a long one, the end of the line. The readers eye then

reverts to the left, looking for a new line. Information is only absorbed within the fixed saccade period and

any data to be after that is likely to be missed. With average body text size of 12 points such an interval

would normally include 5-10 letters and 1-2 words. If the reader cant make sense of the text then the eye

jumps back, in an action that is referred to as regression saccades.

In a space of 10 letters only 3-4 letters are focused on by the readers and the rest is guessed according

to the connotation of the sentence. When we learn to read the saccades are fairly short and the reading

process is time-consuming. As we gain experience in the action of reading we train the eye to engage in

longer saccades, over shorter duration of time. The size and frequency of saccades within a piece of type

are dependent of the many different variables that micro-typography deals with and are in effect theabsolute measurement of a set type readability.

The more correct the setting of type is the more pleasant the reading process will be, the measurable

presence of that would be the length of the saccade.

Digital Current state of standards

By now the separation of content from presentation has been widely established as an industry standard,

table-based layouts are no longer acceptable and the introduction of techniques such as CSS3 and

HTML5 signal more complex (and consistent) layouts and page grids. The tools available for styling texthave made it possible for web designers to build frameworks in order to streamline the design (and

implementation) process whilst staying within design conventions such as grid and vertical rhythm.

The working versions of CSS2, as well as all previous versions of it, revolutionised the way websites are

built and styled. By their cascading nature, elements could be styled once and all subsequent uses of that

element (as well as its HTML sons) would inhirit the properties set. This is a feature that many designers

may take for granted by now, however it led, together with other dynamic systems, to template-based

design and development workflow. In the earlier stages of the internet, and prior to the widespread use of

CSS, the design and development of any digital based work would be measured against the number of

pages of the final product. This has now almost completely changed and work is measured by the number

of templates required to get to the same end result. This would have not been possible if not for the

cascading nature of CSS.

Properties such as colour, font size, indent make the generic setting of body text possible. The tools set

within CSS 1-2 as illustrated in table 2.2.1 laid the foundations for typographical order online.

Note: on first look vertical-align seems to be the missing link to properly align typography on a carefully

calculated baseline. However, the property doesnt serve its full semantical potentialit sets the element

targeted with its parent element. The default value of vertical-align is in fact baseline and its more

common uses might be sub-case or super-case a character, for example

vim

was set in sub case usingthe vertical align property.

Tools and Frameworks

There is an abundance of web tools and frameworks that developers and web designers can use in order

to enhance their work. The sets of tools available online today allow designers to push their designs

forward in both the macro level, placing elements within a carefully calculated grid, and the micro,

typographical level.

Eric Meyer Reset CSS

Meyer has published an open source CSS framework (2007) as part of an attempt to regulate web design

and eliminate cross browser rendering problems. The file has been massively used and cited in other

frameworks. The purpose of the Reset CSS was quite literally reset any form of inhirit browser styling.

Removing all browser-based behaviour has enabled the designer to start his designs on a clean sheet(and avoid browser based incosistencies later on). All browsers have a default CSS file that styles

elements rendered such as lists or heading, unless otherwise instructed. Meyer has thoroughly traced all

of those browser-inherited behaviours and compiled a compact reset file that ensures a better translation

of a design across browsers.

Meyers work is important not only for simplifying the work of web designers and advocating correct

workflow but as it was in effect the first widely-used and openlydistributed CSS framework. Despite

being limited in scope, the free distribution model encouraged designers to not only use Meyers work but

also share their own code snippets and thus controbuting to the everincreasing open source nature of

the web design community.

On a more technical level Meyer has advocated the use of CSS to its fullest, pushing towards semantic

and accessible websites. The reference to such obscure elements was suggestive to front-end

developers to exploit a wider range of acronyms and attributes.

blockquote:before, blockquote:after, q:before, q:after {content: ''; content: none;}

Blueprint CSS Framework

Blueprint was the first framework that offered a comprehensive set of CSS tools. It encompasses various

elements of grids, typography and forms and included alternative style sheets for Internet Explorer as well

as print. Today Blueprint might seem to be limited in scope, however its importance in promoting clearer,

more ordered, web design in worth noting . The extent of work that was put into very elementary HTML

elements such as forms and link buttons was the first step toward better design for the web and lead the

way to more progressive solutions.

960 CSS Framework

The issue of ideal screen resolution for the web has been a widely discussed, The argument was mainly

split between between 960 pixels and 1024 (and higher as time progressed). The source of the problem

lays in the fact that users view sites on different machines, with subsequent variety in screen resolution. It

is not only browserinherit behaviour that alters the user experience but also the resolution on which it isviewed, particularly when absolute values are used. 960 CSS framework focuses on a grid with overall

width of 960 pixels.

Like all frameworks the main purpose of his work was to allow quick prototyping as Smith (2008)

mentions in his blog, he did not attempt to build a comprehensive (vertical and layout grid based) solution

but simply a tool for quick mocking-up, a starting point for front-end developers. Additionally, the 960 CSS

was not aimed at providing cross-browser consistency it only supported browsers classed as A grade,

a phrase that was coined by Yahoo10 and refers to all browsers with a certain level of rendering engine.

Evidintly, the setting of body text and the baseline grid the 960 grid is the most basic, the margins are the

same across all text sizes (table B.1) and the lack of vertical consistency is apparent (figure 2.4.3).

unit: pixels h1 h2 h3 h4 h5 h6

Margin-bottom 20 20 20 20 20 20

Line height - - - - - -

Table 2.3.4.3 Comparison of heading properties in 960 CSS framework

The 960 framework was written with the clear intention to give designers the tools for horizontal grid.

Being able to lay out items perfectly on a grid that works visually, aesthetically and most importantly

dynamically was (and still is) the holy grail.

Baseline CSS

Out of all of the CSS frameworks the Baseline CSS is the most comprehensive one. Not only does the

system offer tools for grids, forms and of course type, the developer also included alternative style sheets

for iPhone in addition to the print and Internet Explorer.

The Baseline system makes significant effort in order to accommodate a vertical rhythm usingtypographical understanding and mathematical work.

Baseline CSS Interview Stphane Curzi

You have mentioned on the site11 that you were missing a line-leading property. The obvious question

would be why not to use line-height?

There is a difference in the line-height and a leading, I which I could simply use the line-height but as it's

stand right now the type get centred in the line height with equal height at the top and bottom. A leading is

a value that is applied to the bottom of the line. Working with a baseline grid, the most important part is a

consistent type baseline, so by using a consistent line height you gain a consistent baseline, simple but Inever thought about it before starting to work on Baseline.

Were there any other CSS elements you were missing?

Being able to align not on the bottom but on the type baseline would render my framework almost

unnecessary, after that - thinking of type only - a true leading is the big one.

On big thing missing is good support for hyphenation, it's probably one of the property that would help the

most the visual impact of type on the web. Even if people don't think about it, hyphenation plays a big role

on the look of type column. Any other type property would be welcome also.

Can you describe the mathematics you have used on setting the baseline grid?

Pretty basic actually, I started by setting everything on the same line-height and "push" the type visually

on the baseline with a top value, so right now it works perfectly with Helvetica on Safari and Google

Chrome. The other browser are less predictable but the overall look is not bad either, just not pixel perfect

like what I was aiming at.

How do you see CSS3 pushing the envelope in terms of more visually consistent setting of type online?

@font-face comes to mind as one of the big thing coming. To finally have a choice of font would bewelcome but I fear that it will bring a lot of ugly website, the same thing happen when people started to

use computer to design, too much ugly fonts out there.

Are you considering using CSS3 columns in the coming versions? pushing the aesthetic more towards

print?

The first version of Baseline was build with CSS3 columns and padding to push the typo on the baseline.

I later find out that by using relative positioning I would gain in stability and simplicity, unfortunately that

method does not work across CSS3 columns so I chose stability mainly because almost no browser

support the CSS3 columns right now.

I'll probably try and find a solution when more browser will support the column spec.

Despite its prominence in our life, the internet is still young the initial effect this had was an increasing

numbers of businesses and individuals looking to get an online presence, mostly with little budget. This

led to an abundance of sites where the design level is low, especially the attention to details. Issues such

as typography, exact margins and word-spacing are being pushed aside. Interestingly, a similar process

was taking place in the print industry when movable type machines were made more affordable the

market was flooded with books whose design level was questionable. It was not until later in the 20th

Century that the industry has stabilised and the level of output has become more consistent.

The ability, or rather the lack of it, of CSS to accommodate coherent designs has promoted other, less

recommended solutions, essentially hacks, in order to achieve sufficient flare in their designs. It is only

the recent introduction of new elements in CSS3 that has promoted the discipline to the forefront of the

sector again. In many ways the gaps in previous versions of CSS have created the need for a more

streamline work flow, which in return developed the demand for CSS frameworks.

The fundamental difference between typesetting for print and typesetting for screen is still the control the

user has over the copy. The end of user neednt a trained professional to publish new content and if not

given the apropriate guidance the user is likely to make commmon panctuation, spacing and other styling

mistakes this is bound to change with the development of CSS3 and the raising attention to detail.
