This is more a CSS question than a Rails one.
In AWDwR, in the script.aculo.us section talking about auto-completion,
it says
“It is worth highlighting that there is no JavaScript to enable the
arrow-up, arrow-down, highlight behavior of the list. It is enough to
provide the stylesheet above; it turns out that all
- tags support
- one
- two
- three
that behavior (in relatively modern browsers) and just need styles to
show off the changing state.”
So am I right in believing that the following .html file would display
something like a selection box, when arrow-up, arrow-down and mouse
hover events happen? Doesn’t seem to. All other CSS select boxes on the
Web have at least a :hover definition, and a little bit of JavaScript
for IE.
