I'm quite new to the WordPress and blogging thing, so I have absolutely no idea how to add stuff yet. Therefore I need some help. My blog (http://regnbuensende.dk/) has a lot of empty space on both sides, and I would like some kind of wrapper to fill that space. I've tried finding some ads that would look good on my blog, and would like them to be placed in the wrapper (that I haven't got yet), so right now I can only get the ad to show in the sidebar from my Vortex theme.
Can anyone help me (I need detailed help, since I'm so new with all this)? I want to add a wrapper and fill the wrapper with ads (the ads I have are HTML codes).
