Currently, the Left Frame is not very usable when large font sizes are used or when it is resized.
This was mentioned in the Usability Report:
"Users may be confused by the appearance of the left hand frame if they try to adjust its width. R: Make sure that the legibility of the frame contents is maximised when the frame width is adjusted."
I have posted a link to the patch along with screenshots of the changes here:
I spent a long time trying to fix this many other ways (i.e. trying to just CSS changes), and finally found this solution which seems to be the best way to fix the problem.
I'll try to look into it soon. I need to switch over to the SVN version first.
Update: Night draws near. I'll try to investigate further tomorrow. If I don't get to it tomorrow, it may not be until June 6th when I will get to it because I have a family reunion from June 1st to 4th and most people are not leaving until June 5th.
back to cms/css/cms_left.css fixes the problem of the other sections being broken. The only downside is that there is a different background color behind some of the links when the left frame's size is reduced. That's not a problem.
I'll plan on eventually creating a new patch that addresses the "Site Content", "Newsletters", and "Security" sections. However, if you want to fix the Site Content without breaking the other sections, just uncomment "height: 23px;"
Yeah, the background missing is caused by <li> elements having the float: left CSS attribute, and the container <ul> doesn't have this - so the background contents gets erased. If you add float: left to the <ul> it fixes that problem, but the other sections are still broken - this potentially could take a while to fix properly.
