Joomla! Documentation™

The original JA Purity template was provided from JoomlArt.com as a zip but the latest files have been installed along with Joomla. The relevant files, index.php, can be found in templates/ja_purity. If you've been following the tutorial, you can download a tutorial version of the template that installs to the templates/my_japurity folder. Inside the folder of the template, the files are located as follows:

    <location of template>/css/styles/header/XXXXX/style.css
    Note: XXXXX is substituted for whatever style color you are trying to change.

Change:

#ja-search {
	background: url(images/icon-search.gif) no-repeat center left;
}

To

#ja-search {
	background: url() no-repeat center left;

}
