Controlling Column Padding with the Blueprint CSS Framework - Review: using the append-x and prepend-x CSS classes independently
(Page 2 of 4 )
In order to review certain previous concepts, before I explain how to use the “append-x” and “prepend-x” generic CSS classes in conjunction, I'd like to help you to recall quickly how these classes can be used separately to aggregate a specified number of grid units to a column of a web document.
Below I included two code samples developed in previous tutorials that illustrate the use of classes in question. Here they are:
(example using ‘append-x’ classes)

From the pair of code samples shown above, it’s clear to see how simple it is to aggregate grid units at the beginning and end of a certain web page column via the “append-x” and “prepend-x” classes. Obviously, by using the classes separately, it’s possible to adjust the padding of a column independently, in perfect alignment with the background grid.
However, as I explained in the introduction, it’s feasible to combine both classes within the same design, in this way assigning the same padding to a selected column. This is what I’m going to explain in the following section, by introducing only a few minor changes to the markup of the previous web page.
Want to see how this will be achieved? Click on the link below and read the next segment.
