Re: Activity Stream background different for admins and groups
CSS can’t make something beautiful that’s a design consideration, you have the control required now though.
p.s always use shorthand CSS property declarations, unless there is a specific reason to need to state the sub properties so ‘background’ rather than background-color’ initially, background-color if preserving a previously declared background containing an image call or other background properties.
On a sidenote as a rule of thumb adding markup should be considered a last resort, especially ‘divs’, unless generating actual new elements.
As is often the case dynamic site apps such as WP, Drupal et al have a tendency to divitis or markup bloat, generating much markup where it’s not absolutely necessary, not a huge problem, but slows page loads, and creates overcomplicated DOM structures.
