What's the difference between <em> and <i> also <strong> and <bold>?
What about <sub> and <sup>? They both look identical to me. Any answer will be greatly appreciated. -Thank you.

They have theĀ same effect on normal web browser rendering engines, but there is a fundamental differenceĀ between them.
Think of three different situations:
web browsers
blind people
mobile phones
"Bold" is a style - when you sayĀ "bold a word", people basically know that it means to add more, let's say "ink", around the letters until they stand out more amongst the rest of the letters.
That, unfortunately, means nothing to a blind person. On mobile phones and other PDAs, text is already bold because screen resolution is very small. You can't bold a bold without screwing something up.
<b>Ā is a styleĀ - we know what "bold" is supposed to look like.
<strong>Ā howeverĀ is an indication of how something should be understood. "Strong" could (and often does) mean "bold" in a browser, but it could also mean a lower tone for a speaking program like Jaws (for blind people) or be represented by an underline (since you can't bold a bold) on a Palm Pilot.
