Matching Columns for Fixed Web Page Layouts with CSS - Building a fully-balanced fixed web page layout
(Page 4 of 4 )
As I stated in the section that you just read, here is the complete source code of the three-column sample web page that you saw before, in this case including the CSS styles that make the respective main bars look perfectly balanced:

As shown above, the sample web page now displays its main bars neatly balanced. Of course, the tricky part of this technique is based upon assigning one background color to the previous "mainwrapper" DIV, and a different color to the centered column, in this way achieving the desired visual effect with the columns in question.
The prior code sample can be easily complemented with an illustration of the so-called evened columns, as shown below:
And naturally, the major advantage in implementing this CSS-based approach rests on its flexibility; it can be used with both liquid and fixed web page layouts. As you can see from the previous example, there's no need to be a guru of web design to build a consistent web page layout.
Final thoughts
In this second article of the series, you hopefully learned how to implement a fully CSS-based solution to keep the main columns of a given web page completely balanced, in this case using a fixed layout.
This educational journey isn't finished yet. In the last part of the series I'm going to teach you how to build completely even web page columns that also include some appealing background images.
Now that you've been warned, you won't want to miss it!
