TYPE RENDERING 

a designer cannot ensure that users will see HTML text exactly as designed. 

RENDERING STRATEGIES - Black and White (bi-level) - Grayscale (antialiasing , resampled for image) - Sub-pixel (colored pixels, LCD) 

RASTERIZATION ideal shape black & white grayscale sub-pixel 

CURRENT IMPLEMENTATIONS Windows Mac OS X iOS iOS GDI-Grayscale GDI-ClearType (ClearType applies only to TrueType-based web fonts) DirectWrite Core Text (with Quartz) Core Text (with Quartz) Core Text (with Quartz) GDI-Grayscale GDI-ClearType (ClearType applies only to TrueType-based web fonts) DirectWrite Sub-pixel (opaque background , normal orientation) also for Retina displays Sub-pixel (opaque background , normal orientation) also for Retina displays Grayscale sub-pixel (disabled by default) Fonts Hinting Sub-pixel (opaque background , normal orientation) also for Retina displays Sub-pixel (opaque background , normal orientation) also for Retina displays Grayscale sub-pixel (disabled by default) 

Mac OS X and iOS Generally very reliable Windows Font format is important Hinting matters 

CONCLUSIONS - Accept the reality - Assume the worst - Use web fonts - Beware of big type - Wait for a future Font smoothing explained - szafranek.net 

CSS TEXT 

SPACING The space bar is not a design tool. ELLEN LUPTON, THINKING WITH TYPE Between ideographic and non-ideographic text. - an en space (plain text) - 1/4 of an em space (InDesign) - auto space (CSS) - necessary ?

PUNCTUATION PROHIBITIONS Simplified Chinese (Ark Version, like webkit) Characters that are not allowed at the start of a line : !%),.:;?]}¢°’”‟›℃∶ɺɻʭʥ㽆〞﹚﹜ʂˋʣɼɽɿʀʁʧʩ not allowed at the end of a line : $(£¥﹙﹛ʬʪʮʰʤ㽅ᶸˈʢɽʦʨˊˇ http://en.wikipedia.org/wiki/Line_breaking_rules_in_East_Asian_languages not allowed at both ends of a line : “'‘ can't be separated: —…‥ https://github.com/mathiasbynens/unicode-data 

ISSUEs of line breaking strategy for Chinese on Chrome and Safari Wrapped with a span tag for each word, line break strategy becomes ineffective. word-break: break-all ⊗ ⇢ PROHIBITIONS ⊗ wrap word & punctuations ⾫ ⇣ new line breaking bug display: inline-block | run-in ⊗ √
