I know there are a lot of post about overflow problem in FF (most for old version) or elsewhere but I can’t find something related to my example.
I tried this little piece of code which should produce a scrollbar : it works as expected in Chrome and IE but not in FireFox.
<!DOCTYPE html>
<html><body>
<div style="height: 25px; overflow: auto;">
<div style="height: 100px;"></div>
</div>
</body></html>
Here is an online example : http://jsfiddle.net/v7kqP/5/
I am using FireFox 16.0.2. Am I doing something wrong or is it a FF bug ?
Firefox won’t show the vertical scrollbar if it thinks there’s not enough space to show the whole thing. Clearly it thinks 25 pixels is not enough space to show a vertical scrollbar, in your case…
