Regarding the Attachments Grid widget. Whenever I add a border-color property, either in the wf_default_extra.css template or directly in the grid template itself, I break the thumbnail layout - forcing the images in the widget to display in a single column. This will work: Code: .bdImage_Widget_Grid_Container img {border-radius:4px;} This will break it, I'm using an XF color variable but input the intended hex color below: Code: .bdImage_Widget_Grid_Container img {border-radius:4px;border-color:#aaaaaa;} I can insert a border-style and border-width value without any problem. Things go wrong when the color value is inserted, either as a separate property or shorthand.
