Creating Hybrid Web Page Layouts with Negative Margins - Completing a hybrid web page layout
(Page 4 of 4 )
As I stated in the section that you just read, below I listed the complete source code required to build a hybrid web page layout using CSS negative margins. In addition, I styled the header and footer section of the web page in question, but naturally you can modify this and use your own CSS styles.
Having clarified that point, please pay close attention to the following (X)HTML file, which is responsible for constructing the hybrid design that I mentioned earlier:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />

That’s it. Now you have at your disposal all of the source code required to build a hybrid design that uses negative margins to accommodate the respective containing DIVs. Also, if you want to see how the previous web document looks, here’s an screen capture that shows pretty clearly its visual appearance:
Final thoughts
Unfortunately, we’ve come to the end of the series. But overall the experience has been educational, since you learned how to take advantage of CSS negative margins to build different types of web page layouts. Certainly, negative margins aren’t the only approach that you can use to create DIV-based web page designs, but admittedly it is one of the most consistent and easiest to learn.
