Let's go back to a plain old screen.

<BODY>
Something really cool
</BODY>


Something really cool


We can make things bold.

<BODY>
Something really <B>cool</B>
</BODY>


Something really cool

What we are (more or less) telling the browser is: at the <B> start making things bold, and at the </B> stop making things bold.


The same principle applies to italics...

<BODY>
Something <I>really</I> <B>cool</B>
</BODY>


Something really cool


...and underlining.

<BODY>
<U>Something</U> <I>really</I> <B>cool</B>
</BODY>


Something really cool


Back again to a plain screen.

Something really cool


We can use tags in combination if we want to.

<BODY>
Something really <I><B>cool</B></I>
</BODY>


Something really cool

This is an example of nested tags. If you are going to use tag pairs in combination (which you will probably be doing quite a bit), then to avoid confusing the browser, they should be nested, not overlapping. Let me illustrate...

   <THIS><THAT>cool</THIS></THAT>    Overlapping tags.... bad
   <THIS><THAT>cool</THAT></THIS>    Nested tags.... good
