The ability to reuse blocks of code is a blessing and a time saver to programmers everywhere. Web sites are too distinctive to allow you to do very much of this, right? Wrong. You can build a CSS framework to give you the flexibility you need, and use the time you save for the parts of your project that matter most. This five-part series shows you how.
Building a Simple CSS Framework - Building a two-column liquid web page layout (Page 4 of 4 )
If you’re like me, then you want to see how the CSS framework developed in the previous section can be implemented in a truly useful way. With that idea in mind, below I coded a sample (X)HTML file that utilizes the framework to build a primitive web document. The document is composed of two primary columns, as well as the usual header and footer sections. Here it is:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<h2>This is the header section of the web page</h2>
<p>Contents for header section go here. Contents for header section go here. Contents for header section go here. Contents for header section go here.</p>
</div>
<div id="navbar">
<h2>This is the navigation bar of the web page</h2>
<ul>
<li><a href="#">Link 1</a></li>
<li><a href="#">Link 2</a></li>
<li><a href="#">Link 3</a></li>
<li><a href="#">Link 4</a></li>
<li><a href="#">Link 5</a></li>
<li><a href="#">Link 6</a></li>
</ul>

In this particular case, the above sample file illustrates how to use the CSS files that comprise this framework to build a two-column liquid web page layout. As you can see, the framework permits us not only to construct the general layout very easily, but also allows us to include containing areas and title sections within the web document with minor hassles.
The previous example would be incomplete if I didn't complement it with a screen shot that shows the visual presentation of the recently-created web page, so here it is:
That looks pretty good, right? Taking into account that building a web document layout like the one shown above only required coding two simple, straightforward CSS files, the end result is pretty satisfactory.
And as a corollary to this tutorial, feel free to introduce your own improvements to the CSS framework developed before, so you can expand its existing functionality and your web design skills.
Final thoughts
In this first part of the series, I used a few basic examples to help explain how to create a reusable CSS framework, which can be used for building several liquid web page layouts very quickly. As you saw earlier, the whole development process demanded only that we code two simple CSS files.
In the upcoming chapter, I’ll be extending the functionality of the CSS framework to provide it with the capacity for constructing three-column liquid web designs. Thus, now that you know what to expect from the next article, don’t miss it!
