<strong> and <b> tags
Both <strong> and <b> tags render the enclosed text in a bold typeface by default, but the <strong> tag indicates that its contents have strong importance, whereas the <b> tag is simply used to draw the reader’s attention without conveying any special importance.
<i> and <em> tags
<em> and <i> tags render text in italic type format. The <em> tag indicates that its contents have stressed emphasis. <i> is often used to indicate a technical term, a phrase from another language, a thought, a ship name, etc.
