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













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>
