I noticed that unread items in achievements popup have more height than the already read:


The red line is for comparing with background page. Nothing changed, just achievements popup has reopened:


The number of visible items in popup is also changed (on the latter image “last 30 days” option is displayed) since the total height is constant.


This is , according to this answer by a Stack Exchange employee on one of my questions.

This was actually supposed to have padding on both the top and the bottom but another rule was canceling it out. It should look cleaner now.

I suppose the extra padding improves accessibility; some users might have trouble seeing the blue-gray background and would otherwise have no other indicator that an item is new. For me personally it isn't necessary, but I'm too lazy to write a userscript / custom stylesheet to remove it.

  • I don't think the asymmetry is by design -- nothing in that answer says that read and unread messages should be different. Also, that answer is a month old but I'm seeing this extra padding for the first time today. – Monica Cellio Aug 25 '19 at 3:15
  • I'll admit that that answer is open to multiple interpretations. Since this question is tagged [bug], chances are one of the SE developers will clarify. – Glorfindel Aug 25 '19 at 12:01
