Prepending Classes in the Blueprint CSS Framework - Review: constructing a two-column web document design
(Page 2 of 4 )
Before I proceed to discuss how to use "prepend-x" CSS classes in Blueprint CSS, let me reintroduce a concrete example developed in the previous article. It demonstrated how to aggregate grid units to columns within a web page via the "append-x" classes.
That being said, here's how the aforementioned code sample looked originally:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<title>Using append class</title>
<!-- framework CSS source files-->
<link rel="stylesheet" href="blueprint/screen.css" type="text/css" media="screen, projection" />
<link rel="stylesheet" href="blueprint/print.css" type="text/css" media="print" />
<!--[if IE]><link rel="stylesheet" href="blueprint/ie.css" type="text/css" media="screen, projection" /><![endif]-->
</head>
<body>
<div class="container showgrid">
<div class="span-24">

As you can see, it's extremely easy to aggregate a specified number of grid units to a selected column via the "append-x" classes. The above sample file shows how to perform this task by appending only one unit to the main sections of the web document, but naturally it's possible to add multiple units.
So far, so good. At this point, you've hopefully recalled how to utilize the generic "append-x" classes in Blueprint CSS, meaning that it's time to explore a few others provided by this framework. Thus, in accordance with the concepts deployed in the introduction, in the section to come I'm going to show you how to make use of the "prepend-x" classes.
