Proposition to change the prefixing policy

When a browser vendor implements a new css feature, it should support it, from day 1, both prefixed and unprefixed, the two being aliased. If a style sheet contains both prefixed and unprefixed, the last one wins, according to the cascade. Authors should write their style sheets using the unprefixed property, and only add a […]

Opera Mobile Emulator with support for (some) -webkit vendor prefixes

Opera, along with Mozilla, announced at a CSS Working Group meeting that we would support some -webkit prefixes. This is because through our site compatibility work, we have experienced that many authors of (especially mobile) sites only use -webkit prefixed CSS, thereby ignoring other vendor prefixes and not even including an unprefixed equivalent.

CSS :nth-letter()

Adobe is working on implementing :nth-letter() in Webkit: The desired syntax was :nth-letter(), where the argument would (ideally) take the same values that :nth-child() can (e.g, a simple index, even/odd, or an expression like 2n+4).

One interesting alternative to floats that people are turning to more and more lately is to set the display value of an element to […]

text-indent: -9999px; revisited

Turns out, this works even better (and is more concise): .hide-text { text-indent: 100%; white-space: nowrap; overflow: hidden; } As Zeldman put it: Really long strings of text will never flow into the container because they always flow away from the container. Performance is dramatically improved because a 9999px box is not drawn. Noticeably so […]
