Using the Padding-Top CSS Property with H2 Headers for Image Replacement
In this penultimate installment of the series, I demonstrate how to apply Langridge’s image replacement method to all of the H2 headers of a trivial XHTML document. The inner workings of this approach are very easy to grasp, so you shouldn’t have major problems using it within your own web pages.
Using the Padding-Top CSS Property with H2 Headers for Image Replacement - Binding the CSS to the structural markup (Page 4 of 4 )
By far, the best way to understand how Langridge’s method can be used for changing the default style of H2 headers is by creating an XHTML document that contains a few of these elements. Below I coded such a document, so you can copy and paste its source code for testing purposes. Here it is:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<title>Stuart Langridge's image replacement on H1 and H2 elements</title>
<style type="text/css">
body {
padding: 0;
margin: 0;
background: #fff;
font: 1em Arial, Helvetica, sans-serif;
color: #000;
}
#wrapper {
width: 960px;
margin: 0 auto;
background: #ffc;
}
#header, #content, #footer {
padding: 20px;
}
/* apply image replacement on H1 element */
#header h1 {
width: 400px;
height: 0;
padding-top: 200px;
background: url(h1.png) top left no-repeat;
overflow: hidden;
}
/* apply image replacement on H2 elements */
h2 {
width: 300px;
height: 0;
padding-top: 150px;
background: url(h2.png) top left no-repeat;
overflow: hidden;
}
</style>

Since the above web page has been used with other image replacement methods covered previously, at this point its structure should be pretty familiar to you. Obviously, the most important thing to note here is the inclusion of the corresponding H2 element in each section that composes the document, which, when tested on the browser, generates the following output:
Naturally, the final result produced by this approach is identical to the one obtained with others. Nonetheless, as you saw in the earlier example, the approach’s internal implementation is completely different.
Feel free to edit all the code samples shown in this tutorial, to build your background in using Langridge’s method for improving the look and feel of different web page elements. The experience will be instructive and fun!
Final thoughts
In this penultimate installment of the series, I demonstrated how to apply Langridge’s image replacement method to all of the H2 headers of a trivial XHTML document. Undoubtedly, the inner workings of this approach are very easy to grasp, so in theory you shouldn’t have major inconveniences using it within your own web pages.
Now, moving forward, in the last tutorial I’ll be discussing how to use this handy method for styling some <a> elements, in consonance with the trend followed in previous parts of the series.
