How to add background image behind container
<p>So i am currently working on a small assignment we have in school as practice but i don't know how to add a background image behind container. Here is a example i found quickly of what i want to achieve, note the background image <a href="http://www.njuskalo.hr" rel="nofollow">http://www.njuskalo.hr</a>. I tried adding a background image to body but that doesn't work either. Also i made two new div tags (.left and .right) to try and add it on the sides of container, also didn't work.
Here is my code: <a href="http://textuploader.com/d5j5d" rel="nofollow">http://textuploader.com/d5j5d</a>
Also note that i changed and erased a lot of stuff trying other things. And please go easy i know the code is a mess but it's something i am doing at the last minute so feel free to point out all the mistakes.</p>
