What is your biggest takeaway from the article?

There are several options you can try when creating full-page backgrounds. The one that is most appealing to me and seems to be the easiest is the progressive CSS3 method. Setting the background-size to “cover and setting the background image to no-repeat center and fixed” ensures that the image will always fill the entire background. I have used this method in the past but I applied the rule to the body tag rather than the html element as the article suggests. This actually makes more sense since the html element will always be the height of the browser window. It works in Chrome, Safari, & Firefox. It only works in IE 9+ and Opera 10. Since IE is going away soon I wouldn’t worry too much about it not working in IE8 or less.
