<!-- CSS 2.1 Reference

Property Name: font-size

This property determines the size of the font that the element contains. Apart from being able to assign absolute unit values (pixel px and point pt ), and relative unit values ( percentate % and Em em ), there are also property-specific values that can be assigned. You may assign an explicit word size that defines font size in comparison to the default medium value. These word size values are: xx-small, x-small, small, medium, large, x-large, and xx-large. Additionally, there are two calculated values that may be assigned: smaller and larger, which change the size of the font in relation to the parent element.
