How to delete global style declaration

[krishnavashisth]

Hi,

I've an HTML page referencing to external css file theme1.css.
Theme1.css has global declaration of:

 * { font-size: 12px; }

I've a limitation for not to amend changes in the css file. As this is commonly used for other HTML files.

Is there any idea, that I could delete or skip this declaration to be executed at every time my page renders to the browser?
