Typography “Typography exists to honor content.” Robert Bringhurst – Verbal & visual – Creates hierarchy to understand relationships Web typography considerations – Legibility – Readability – Accessibility / Customization Rachael Gilg | INF 385E | October 12, 2004 Evolution of digital typography Graphical User Interfaces HTML – Separates design from structure – Emphasis on interoperability, not visual style CSS (Cascading Style Sheets) – separates visual style from document structure – greater typographic control with less code – more formatting options Rachael Gilg | INF 385E | October 12, 2004 Font styles on the Web Best choice for screen: sans-serif, large size, exaggerated x-height Verdana x Times x High contrast with background color Anticipate size variability Avoid ALL CAPS & use “downstyle” headlines Use emphasis sparingly, 1 parameter – Colored / underlined have special meanings Specify fonts for each platform Be consistent Rachael Match style to content Gilg | INF 385E | October 12, 2004 Formatting Overall pattern of organization & visual contrast – Establish visual pattern using grid system Alignment – Left-justified with ragged edge is best Line Length – Columns of text no wider than 365 px. – Anticipate expanding layouts / wrapping White space is your friend!
