In most cases, don't change font faces. All in all, you can stick to Bold <B> and the </B>.

With almost ALL HTML codes, you MUST put the Closing tag after the affected section.

For another type of HTML enhancement to text, you can use Italics, which replaces the B with an I.

Also you can combine the two, HOWEVER, you MUST remember to take the Closing Tags and put them in the REVERSE order you put the tags in at the start. For instance if you do Bold and then Italic, then put in the the close for the Italic first then the close for the Bold.

Other enhancements are to change colour or size. For that, you DO need to use the <FONT> tag and appropriate closer.

Does that make sense?
