Re: Why doesn't the "Bottom" module extend all the way across the page?
Hi,
I don't see the photo so will just respond about the typical situation. The page footer has a "container" div just as the page's header and middle sections do, to contain content, so if the "Fixed Width" option is on, then all the container divs are restricted to a width of 1170 pixels to prevent lines of text, for example, from going the full width of wide displays; this kind of limiting width is generally considered good for readability, etc.
Do you think this Fixed Width limit is what's causing the restriction in your site footer? If so, either the Fixed Width option can be turned off, although that causes the header and page middle to also go full width of the browser window, or you can add a custom CSS rule to only widen the container div in the page footer:
.main-footer .container { max-width: 100% !important; }
This should be input on tiki-admin.php?page=look under the in the Customization tab, in the Custom CSS textarea.
If I misunderstood your situation or if this fix doesn't get the results you want, please post again with the details.
