I've found out that my web app is displayed incorrectly
in Opera because of the following bug:
#one {
overflow: hidden;
position: fixed;
height: 100px;
width: 100px;
}
#two {
position: fixed;
bottom: 0;
left: 0;
right: 0;
top: 0;
background: #ccc;
}
and html:
<div id="one">
<div id="two"></div>
</div>
instead of occupying the whole view port #two is cut by #one in Opera.
Is there a way to workaround this not affecting other browsers?
This bug is fixed in Opera 11.60, it now behaves exactly like other browsers.
