HTML Big Element
(
<big>
) renders the enclosed text at a font size one level larger than the surrounding text (
medium
becomes
large
，例如)。
The size is capped at the browser's maximum permitted font size.
Usage note:
As it was purely presentational, this element has been removed in
HTML5
and shouldn't be used anymore. Instead web developers should use the CSS
font-size
property to adjust the font size.
This element has no other attributes than the 全局属性 , common to all elements.
Here we see examples showing the use of
<big>
followed by an example showing how to accomplish the same results using modern CSS syntax instead.

font-size
property to increase the font size by one level.
