CSS Function Syntaxes (color and otherwise) - Tab Completion
There’s a big change coming up for how we write colors in CSS. Tab Atkins recently changed the color functions syntax in the CSS specification. So in future, we will write rgb(0 255 0 / 50%)
instead of rgba(0, 255, 0, 50%)
. This might sound awkward after years of doing it differently, but the reason for it are the new color functions available in CSS Colors Level 4, including color()
. You can read more about this in Tab’s blog post, but for now be assured that the old syntax is likely to be supported forever in our browsers thanks to legacy support.
