What is the difference between the <strong> and <b>

Answer 1

it's really all about semantic HTML.

<b/>

tag doesn't tell you anything about the content, and is thus not a semantic representation of your content.

<strong>

on the other hand gives you an indication about the semantic meaning of the item you're putting the tag around. Same goes with

<i> and <em>.

Answer 2

Matt says that the only difference between the two tags is that that <strong> tag refers to presentation, while the <b> tag is a semantic label. But he reminds us that in practice they both do the same thing, every browser just uses the tags to make text bold. [1]
