CSS text-size-adjust
This page is for tracking the development of a standard 'text-size-adjust' property. There are three known vendor prefixed implementations of it: -moz-, -ms-, -webkit-.
Web developers are using at least 4 prefixed implementations in the wild, including -o-text-size-adjust which Opera does not implement (as of 2012-088 per Florian of Opera on the CSSWG telcon that morning).
- Tantek
property definition
- values: auto | none | <percentage>
- Initial value : auto for smartphone browsers supporting inflation, none in other cases (and then not modifiable)
- Applies to: all elements
- Inherited :yes
- <percentage> :yes, refer to the corresponding size of the text font
- Media: visual
- Computed value : the keyword or the percentage value
- Animatable: no
- auto
- mobile browsers may implement a text inflation algorithm
- none
- browser must not do any automatic text inflation
- <percentage>
- inflate text size by the <percentage> given
Text inflation ... (needs to be defined).
editor next actions
must for editor draft
- define text inflation (as requested by CSSWG 2012-088 telcon before checking in as editor's draft)
should for FPWD
define percentage values
The definition of <percentage> is not particularly clear.
- Need to figure out what iOS Safari actually *does* for percentages.
A somewhat reasonable guess might be that it sets a maximum inflation level, but relative to what? Is '0%' equivalent to 'none', or is '100%', or are they both different from 'none' in some way? If it actually just specifies the inflation that would be pretty bad.
- Create some test cases to figure out what iOS is doing for %s and test them on an iOS device touch.
- write-up percentage details accordingly
