have no absolute influence over CSS style definitions I define on my CSS style sheet file? What I mean is that... let's use this example for simplicity's sake, if in my master_css_file.css I say that all "h1" tags need to be red, I'd like to know what could I do to make specifically all h1 tags inside that No-CSS zone to not change to red. Please note this is just one simple example, I want a general solution that would work for all tags.
I'd like to know if such feature is possible because I need to have a "No-CSS zone of my site" so that no matter what style definitions I enter on my master CSS file, nothing within that DIV will change. It will have normal default browser definitions just as if no CSS had being used in the first place.
I wish to do this so I can have more control over my CSS. You see, sometimes I have to use include('path/to/file.html'); in PHP and when including an HTML document (even if just what's inside the <body> tag), most of the content will not have preserved its original style definitions. So I am asking this question here to see if it would be possible for me to have more control over my CSS and avoid having these "included HTML files" so messed up by my own CSS master file.
