After I designed a theme to my SharePoint 2007 site I came across a small problem. Well it was not exactly a problem it was more of a hassle I encountered. The current SharePoint Intranet I was working on contained quite a lot of sites and I didn't want to change the site settings within each site in order to change the theme. Thankfully, SharePoint 2007 allows you to apply a Custom CSS from your theme.
In order to change the theme across the whole SharePoint Intranet carry out the following:
- View the source of main portal homepage and look for a line which looks something like this:
<link rel="stylesheet" type="text/css" id="onetidThemeCSS" href="/_themes/Intranet/Intr1011-65001.css?rev=12%2E0%2E0%2E4518"/>
- In Site Settings click on Masterpage and scroll down to the bottom of the page.
- Select the "Specify a CSS file to be used by this publishing site and all sites that inherit from it" radio button.
- Use the link from the CSS HTML tag above excluding anything after the query string. For example: ""/_themes/Intranet/Intr1011-65001.css".
Now the theme should be applied throughout the site. You can change the link for the Custom CSS by changing the directory path.
