Universal Selector in CSS2

CSS2 had introduced a new selector, the universal selector to match any element in your page. The selector is indicated as an asterisk ‘*’. The universal selector could be used to list every element in your page.
For example,

* {font-size: 12px}

This declaration would set the font size of all the elements used in your document to 12px.

NOTE: Even though the universal selector is one handy option, consider the specificity of other selectors for it to work properly.
