HTML Frames - Frame Border

We can make the frame borders invisible by using frameborder attribute of <frame> tag.

Deprecated : FRAME & FRAMESET tags are not supported in HTML5 ,
better to avoid.
Use <iframe> instead.

Example:

<Frameset rows="50%,50%">               
          <Frame src="frame1src.html" frameborder="0">
          <Frame src="frame2src.html" frameborder="0">
     </Frameset>

We can also make the frameset borders invisible by using border attribute of <frameset> tag.
Example:

<Frameset rows="50%,50%" border="0">               
            <Frame src="frame1src.html" frameborder="0">
            <Frame src="frame2src.html" frameborder="0">
     </Frameset>

Note: frameborder attribute can also be specified with in the <frameset> tag to avoid mentioning for every frame within a frameset.

Example:

<Frameset rows="50%,50%" border="0" frameborder="0"> -- This makes border of all frames with in the frameset invisible.     
          <Frame src="frame1src.html">
          <Frame src="frame2src.html">
   </Frameset>
