The difference between <strong> and <b>

The <b> and <strong> elements both make the text appear in bold.

In the early HTML days, the <b> tag was used to emphasize and highlight text.

With the introduction of the <strong> tag it became the preferred way to display important text.

As a general rule, use <b> when no other, more appropriate, tags are available.
