Appending Grid Units with the Blueprint CSS Framework - Review: two-column web page design with Blueprint CSS (Page 2 of 4 )
Before I start discussing how to pre-append grid columns with Blueprint CSS, I’d like to reintroduce the hands-on example created in the preceding tutorial. It demonstrated how to build a basic web page layout comprised of two primary columns, in conjunction with header and footer areas.
Here’s how the example in question looked originally:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

Although it might look rather primitive at first sight, the above code sample shows how simple it is to create a two-column web page design using the generic “span-x” CSS classes provided by Blueprint CSS. In this case, the main column was created by spanning 16 grid units, while the corresponding size bar spans the remaining 8 grid units. Not too difficult to understand, right?
Now that you hopefully recalled how to drop columns across the web document via the aforementioned “span-x” CSS classes, it’s time to continue exploring other classes given by the Blueprint CSS framework.
As I mentioned in the introduction, it’s also possible to append a certain number of grid units to a given column, which permits you to have more accurate control when positioning elements across the web document.
Therefore, in the following segment I’m going to explain how to use a brand new set of CSS classes included with Blueprint CSS, called generically “append-x,” which will perform this appending process in a straightforward manner.
