Just a quick note to say that (using Chromium 31.0.1650.57) the a:hover { border-bottom: ...; }
attribute on the items in the Related list shown when viewing any question pushes all links below the :hover
ed item down by 1 pixel.
Edit: This appears to occur on this Meta site too.
To save 50ms of thinking - this is fixed by adding a { border-bottom: 1px solid #fff; }
(or similar, like padding-bottom: 1px
). :P
