Applying custom css to default theme in sharepoint 2010

Question

I have created a custom styles css and registered it as follows in v4.master using SharePoint:CssRegistration option name="<% $SPUrl:~SiteCollection/Style ibrary/Custom.css%>" after="corev4.css" runat="server"/>

I assumed that my custom styling would be applied to any new site, however any new sites open in the standard default style, obviously I want my custom branding to automatically apply..

I have to mess around in site settings to use the parent theme etc, but even that does not always apply the styles correctly, so I have to go to the parent site and apply the parent styling to substitutes etc.

Other users will be using the site so I want to make it as easy as possible, can anyone offer help?

Answer 1

In order to apply your custom styles & master pages, you need to create sharepoint module (your styles, files & configuration) and Feature with Event receiver(when activated in sharepoint site/sitecollection, it'll apply your module, when deactivated, it rollback default settings related to styles/master page).
