How to add image/ads to the sides of main content : <p>Let's say that I got a div called <code>container</code> that is 1000px wide and aligned to the center of the screen. I would like to add images/ads to the blank space that is left over the the left and right side of that div. It should be fixed and should not move into the <code>content</code> div if the screen is smaller but should instead disappear to the sides when zooming in on the website or having smaller screen.</p>

<p>I am pretty much trying to accomplish what probuilds.net did: <a href="https://i.gyazo.com/746c89429d9ca0e23016469120f2b607.jpg" rel="nofollow">https://i.gyazo.com/746c89429d9ca0e23016469120f2b607.jpg</a></p>

<p>How could that be done? Each side should have individual ad/image code.</p>
