1)<B> is the bold tag i.e if you want to make any text bold, use this tag.
Suppose you want to make "I am a good boy" bold, you have to do this:
<B>I am a good boy </B>
This will give us this: I am a good boy
Cheers! You have just learned your first tag.
2)<U> is the underline tag.
If you want to underline the text in the first example, this is how to do:
<U>I am a good boy</U>
This will give us this: I am a good boy
Great going!
3)<I> is the italics tag.
If you want to turn "Hi there" into italics, this is how to do:
<I>Hi there</I>
This will give us this: Hi there
