Through out the whole site, where [tag:something] is used, or where framework inherits the same behavior, there is a problem with CSS.
Check thismechanics (before the tag, the letter s is hid, but the spacing after the tag is enormous).
I see in CSS, it lacks margin-left property:
margin: 2px 15px 6px 0!important;
That translates to:
margin-top: 2px !important;
margin-right: 15px !important;
margin-bottom: 6px !important;
margin-left: 0 !important;
What it should be though, is something like this:
margin: 2px 8px 6px 8px!important;
Giving some margin to left, and subtracting from right, resulting in a very nice looking tag.
