[html] symbol of <b> and <strong>

When testing in WCAG, the symbol of <b> will take some error, but why? How can we do if we want to bold the font?

The answer: use <strong> instead.

 

<strong> is the standard of XHTML,

<b> is supported of HTML,

 

What is differece between XHTML and HTML? please google it~ :)

 

So, next time, when we want to bold the font, we'd better use <strong> instead of using <b>
