You can’t use some handy CSS selectors like:
- input[type=”text”] for selecting text input elements or
- abbr[title] for selecting all <abbr> tags with a title attribute or
- a[href$=”.pdf”] for all links that point to pdf files
div#column and div[id=”column”] are equivalent selectors, but one doesn’t work in IE6. Handy for when you want to apply a style for everything else.
