HTML 5 <b> tag

Definition and Usage

The <b> tag makes text bold.

The <b> tag is used to define parts of a text as more important then the rest.

Differences Between HTML 4.01 and HTML 5

None, but in HTML 4.01, there was an understanding that you should use CSS to make text bold. This is still the case, but in HTML 5 you should use the <b> tag to define some part of a text as more important than the rest.

Example

The house with the <b>blue</b> door	The house with the blue door
