Often <strong> renders as <b>, and <em> renders as <i>.However, there is a difference in the meaning of these tags:
<b> or <i> defines bold or italic text only.
<strong> or <em> means that you want the text to be rendered in a way that the user understands as “important”. Today, all major browsers render strong as bold and em as italics. However, if a browser one day wants to make a text highlighted with the strong feature, it might be cursive for example and not bold!
