问题 I need to display some interactive (attaching with DOM listeners etc. and event handling) vector graphics in web site I am working on. There is a W3C recommendation for SVG though this format is still not recognized by Internet Explorer support of which is a must (for a public website).

问题 I'm studying the CSS formatting of an absolutely positioned <input> . I'd like it to "stretch" inside its container (which is also positioned "absolute") so that it leaves for instance 30px both left and right, and fills all the space within...

I also read an article from A-List-Apart talking about this kind of technique and found several other questions here dealing similar troubles

问题 I have some images with height=auto because sometimes they are different heights whereas they are always the same width.

问题 When a click event handler is registered on a select element, I find very inconsistent behavior across browsers. I set up a jsfiddle demo. Here's what I see: Firefox 12 on OS X (10.7 Lion): Event fires when the element is clicked. The dropdown opens briefly, does not stay open. Keyboard actions don't generate click actions. Firefox 12 on Linux (Ubuntu Lucid): same Chome 19 on OS X: No mouse or keyboard interaction triggers the click event. Chrome 19 on Linux: First mouse click expands options
