Building a Liquid Design with Evened Margins and Centered CSS DIVs - Completing the development of the centered layout
(Page 4 of 4 )
As I stated in the section that you just read, it's necessary to put together in one single file the CSS styles coded previously, along with the markup of the web page created in the first section. Below I included the definition of this file, so you can study it in detail. Here it is:

Now that you have the chance to see the complete source code of the previous (X)HTML file, I guess that you won't have major problems understanding how it's used to build an elastic, fully-centered design. In addition, here there's a complementary screen capture that shows how the design in question is rendered on the browser:
Of course, you're free to modify all of the code samples developed in this and other tutorials of the series, so you can experiment with all the DIV-centering approaches reviewed here and choose the one that best suits your needs.
Final thoughts
After a long journey, we've come to the end of this series. But overall, the experience has been educational, since you learned different CSS-based techniques for building centered web page layouts with remarkable ease.
If you create this kind of design for your own websites frequently, then it's possible that you may want to take a closer look at some of the approaches explored here.
