Vince — The only way to accomplish this reliably is to wrap the <div class="container"> element with another <div>. You’d need to apply horizontal padding (say, 30px per side) to the new <div>, which would bring your overall layout width to 830px.
Once you’ve done that, you can apply a background image (or color, or whatever) to the body element, and you’ll start to see the results you’re after.

But I don't understand how to "wrap the <div class="container"> element with another <div>" parts. Am I going to add a <div class="container"></div> in style.css or index.php or elsewhere? And what should I put in between <div> and </div> to make the container background white? Would someone please teach me how to do it with codes? Thank you so much!
