For some pages you need to include custom css styles which is only used in that page. When this is the case including this style to App_Themes folder is unnecessary. (It loads this in every page.)

So by this control you can easiliy include your custom css file simply by dragging it onto a page.
You only need to fill the css file path property like : ~/customCssFiles/banner.css
