Headers h1 and h2 and block elements with class=shadow are given a fine shadow to create a 3d effect.
All h1 and h2 headers and block elements with the class="shadow" of the website are given a small shadow via css and javacript manipulation such that you get a plastic or 3d impression. The main color is inherited. We tried to choose the style values in such a way that you can use this plugin without further style adaption. But this is not possible for any case of template, color configuration and font-size such that I give the possibility to create an css-file with name "shadowed-headers_custom.css" in the main plugin folder where you can make necessary adaption to your environment. This file is your own - not present in the beginning - and will not be overwritten by plugin update. Why no options for this plugin? I cannot know your CSS-selectors where you have to make your changes so you are much more flexible than with predefined options.
