What is a <frameset> tag?

Answer:

The <frameset> tag defines a frameset.

The <frameset> element holds one or more <frame> elements. Each <frame> element can hold a separate document.

The <frameset> element specifies how many columns or rows there will be in the frameset, and how much percentage/pixels of space will occupy each of them.

Example:

<frameset cols="25%,*,25%">

  <frame src="frame1.htm" />

  <frame src="frame2.htm" />

  <frame src="frame3.htm" />

</frameset>
