I am attempting to locate some CSS rules but they do not exist in the index.php header tag, nor in the only CSS file which the header references.
Where else could they be?
CSS can be located directly in your HTML files within the <head>
tag wrapped in <style>
tags. You can also style elements inline such as <div style="width:100px;"></div>
CSS files can import other CSS files via @import
. It is also possible that styles are changed or added with Javascript.
You can import a stylesheet directly through .htaccess, but the is only supported by Firefox and Opera at the moment.
