This question is an exact duplicate of:
When I go on meta.stackexchange.com and sort by newest, there is often an item count for the number of featured questions.
Ad then when hovering over the featured tab, the hovering action produces a slight jump of content, because the red border bottom of the hover action is shoving content down by 2px.
Perhaps this can be seen more clearly in this screenshot, where it is more obvious that the border underneath the featured tab has been shoved down and is not vertically aligned with the red border bottom of the "newest" tab.
That being said, I am not able to reproduce this bug on any computer and OS, but I can say this is happening on my 64-bit Windows 7 machine in Chrome Version 38.0.2125.122 m.
Are others ever having this issue?
There is one way to fix this.
If I change the CSS for the
.bounty-indicator-tab by adding a
margin-bottom: -1px, the problem goes away.
