Using Web Page Grids in Yahoo Grid CSS - Extending the use of web page grids
(Page 3 of 4 )
In the section that you just read, you learned how to use standard web page grids to build a three-column web page layout. As you'll certainly recall, common grids evenly split (50% each) the available space of a given web page block. Nonetheless, the Yahoo Grid CSS framework offers another type of grids. Called "special grids," these take up two-thirds of the available space in one block, in this way making it possible to build different kinds of web page layouts.
Regarding the implementation of these "special grids," below I built another sample (X)HTML file that uses them to create a three-column web document layout:

In this case, I defined a "special grid" which contains two units of the sample web document, while the remaining free space is taken up by a secondary block. Of course, the creation of this three-column web page layout will be better understood if you look at the following screen shot, which shows the final output generated by the previous (X)HTML file:
So far, so good, right? At this point, I believe that you know how to use these "special grids" for building more complex web page layouts. Thus, it's time to see how the same sample (X)HTML file that you learned a few lines above can be used in conjunction with different templates and special grids to display different kind of web documents.
These brand new examples will be built in the next section, thus click on the link below and keep reading. We're just about finished!
