This plugin is used to check all h1 and h2 headers and block elements with the class=”shadow” of the blog via css and JScript manipulation. You can change the main color, shadow color, font-size inside of the css-file shadow_header_css.css, but do not recommended.
In this case you have to save this file before updating this plugin. You can do the same and more with css-feature text-shadow but it does not work with Internet Explorer of any version such that this plugin works as IE-hack, uses for better browsers text-shadow or the text-shadow value the user has set.
Requires WordPress Version: 2.7 or higher
