Background color / image

Hey guys, I'm building a website and 70% of the page is content area. Where 15 % on the left is blank and 15% on the right is blank. I want to add a background color or image that covers that 15% on the left and right. Where the content area background color remains white. What is the best way to go about this? Because when I add a background color it also goes into the content area and unless my content fills the page and I change that specific area to background white it shows that image or background color. Any help is appreciated. Thanks!

Hi Austin,

Perhaps I'm misunderstanding what you have in your design already.

Could you post a link or some code to the forum, I might have a better idea what you need. :-)

Austin,

Assuming the content area itself is contained its own div element, you should be able to control the background colour of the rest of the page with the <body> element.

Use the body element selector to apply a background style with the colour you want.

body {
 background:  lightblue;
}

Hello Austin,

I did cleaned up the code for you with markdown. You can see how to add markdown with the Markdown Cheatsheet link here on the forum page. :)

I'd still need your html but it might be the navbar affecting the main content somehow. Make sure the main content is contained in its own area on the page. You'll want to give your #main-content a width and a height of 100%. That is the main content area you need to give height.

Also you can apply a calc() to #main-content function to make sure that no matter how much content is on the div the footer will stick to the bottom of the viewport.

This is true, but if the content area doesn't fill the page it remains the same background color even if I change the height to 100%. Is there a way to force even if there isn't content to make it fill the content area?

you would have to make the main content section a div or a container you would then be able to change the bg colour.

Basically, I just want the white to be from top to bottom whether there is content or not.
