Replacing a modules views

[محروم.كوم]

Is there a way to specify that my theme provides alternative views to a module? I am working on eradicating the left-bar approach to the site layout via CSS, but have discovered that many modules use poor markup so that re-flowing the design with CSS is impossible unless I can fix the markup in these modules.


Also, login and logout are controlled by the users module right? __DEFINE_LIKE_SHARE__
