I came up with an odd issue with the CSS only theme, which I am modifying.
Logged in as an administrator, the toolset button appears essentially at the left margin of the browser on a topic view (other views are ok), but it only appears when I hover in a certain area, which is hundreds of pixels away. As a result, I’m not fast enough to get to the toolset button before it disappears.
It’s for this ID/class: #spMainContainer a.spToolsButton
Changing the left margin by a huge amount does get it closer. Is that a glitch in the CSS only theme or is it something caused by my general theme or some other change I’ve made to the CSS only theme?
