The dotlrn toolbar button styles make those buttons dancing when the mouse is on and goes out, due to border style differences of
.dt-action-list
.
The solution could be that #dotlrn-toolbar .dt-action-list a
style puts a 1px border, instead of current border: 0px
.
On the opposite side, #dotlrn-toolbar .dt-action-list a:hover
should not have any border.
I prefer those buttons to look as developer support ones, so I would use the border. I write this post looking fordward .LRN leadership team approval.
