I like to document things that I find annoying so that other people can be annoyed by them too, so here’s one for today: Windows IE doesn’t like window names that have spaces in – any JavaScript that tries to target them will fail. Firefox and Safari don’t have a problem with them.
Safari & CSS User Interface colours
I’ve recently encountered a stylesheet that uses the CSS user Interface colours defined here:
http://www.w3.org/TR/REC-CSS2/ui.html
My attention was drawn to it because it was a problem. a:hover was defined as color:HighlightText, and body had background-color:Background, the result of which was that I got white text on a white background when rolling over links. This makes it sound like these values are not set properly by Safari, or that it doesn’t match Safari’s own internal style sheet. For example if I select text on a page with neither of these styles set (i.e. black text on white), I get my system selected background colour, but the text remains black. This would indicate that Safari considers HighlightText to be black by default. But when I ask for that colour by name, I get white instead. Is this a bug?
