While having a separate slider thingy seems to be a nice workaround if alpha doesn't make it into the spec, it puts additional burden on part of the web developer and may preclude the use of platform-specific color chooser widgets. Additionally, it isn't clear to me how to extend a color chooser to contain an alpha component later on (say, in HTML6) - if that is possible at all in a simple, backwards-compatible way. > CSS has also trained many of us authors that alpha is a component of > colors with its rgba() syntax. Interesting. I know of its existence, but almost never use it. Cheers -- Nils Dagsson Moskopp <http://dieweltistgarnichtso.net>
