The tag FRAME in HTML permits you to display more than one HTML document within a single browser window by dividing it into sections known as frames. Frame targeting is controlling which frame the information is going to. Below is a very simple block of code to explain this process.
<frameset rows="40,*">
<frame src="text1.html" name="smasher1">
<frame src="text2.html" name="smasher2">
</frameset>
This is setting up the frames and naming them smasher1 and smasher2. When you need to put information into a certain frame you use the TARGET tag. Originally we were displaying text1.html in the first frame named smasher1. Now if we execute the command below text1 is now replaced with text3 in the first frame (smasher1) and the second frame is still displaying text2.html ...
<a href="text3.htm" target="smasher1">
