I would like to give some kind of indication to the user when text has overflowed and is too large for a container.
I'm using overflow:hidden so, there is a chance that some text will not be visible and I want to find a way to let the user know when/if this happens.
The text-overflow style would work for this but FireFox does not support it.
Update: Credit to @Galled for this link: text-overflow:ellipsis in Firefox 4? (and FF5) which shows how to emulate text-overflow:ellipsis in older versions of FireFox.
Looks like text-overflow:ellipsis is working in the more recent version of FireFox as explained here: https://developer.mozilla.org/en/CSS/text-overflow#Browser_compatibility
Update: I really like this JavaScript solution ( Determine if an HTML element's content overflows ). Of course, using JavaScript will give you a lot more control over how overflowed content is displayed though I was looking for a pure HTML/CSS solution.
