Yesterday I published the CSS2 and Backgrounds & Borders mobile tables.


CSS2 is the table that contains all properties that were never redefined in any CSS3 module. It includes such vital properties as display, position, andoverflow. Backgrounds & Borders, despite the name, is mostly about backgrounds and a few miscellaneous properties. I test border-radius, but the other border-related property, border-image, is WAY too complicated for me.


On mobile there are three declarations that merit particular attention: overflow: auto, position: fixed, and background-attachment. Despite their apparent differences they have one important aspect in common: there is now an element that should be scrolled and moved (or not scrolled or moved) separately from the page as a whole. That turns out to be a challenge for many mobile browsers.
