MOSS Themes - Order of loading

There are already some blog posts on the order with wich SharePoint loads its css files. So I won't go into detail on that.

However I want to give you some info on an issue I had not long ago.

Situation

Custom Masterpage
Custom Theme on Root site
Other Custom Theme on child that touches some similar styles with other colors

Problem

The last css to get loaded was the one of the parent theme

Solution

Moving this tag

<SharePoint:Theme ID="Theme1" runat="server"/>

to be in front of

<asp:ContentPlaceHolder id="PlaceHolderAdditionalPageHead" runat="server">
</asp:ContentPlaceHolder>

More Info

I used a custom masterpage together with a theme. Because I wanted to do all css with the theme I moved the tag to just in front of the tag.
However when you configure a theme on a subsite it gets placed in the "additional page head" wich caused the above mentioned caution.

Moral

When designing your custom masterpage, think twice when moving tags .. and test test test.

Kind regards
