Depending on the design and colors used on the pages contained within each frame in the frameset, it may not be immediately obvious where the boundaries are between the individual frames. In order to make it absolutely clear, you can use the frameborder attribute which will cause the browser to render a visual delineation (most likely as a 3D or bevelled border, but it very much depends on the style of the browser that you use). If the frame is resizable (which it will be unless you use the noresize attribute to instruct the browser otherwise), the frameborder will provide the user with something obvious that they can grab hold of to change the frame’s size.


The border removed for both frames:

<frameset rows="100,*" >
  <frame src="header.html" frameborder="0"/>
  <frame src="home.html" frameborder="0"/>


The HTML specification says to use "1" to signify ‘border on’ and "0" for ‘border off’, but some browsers will also honor values of "yes" and "no". If no value is specified, no border is applied.

Every browser listed supports this attribute.

Note that to remove the border entirely, for example removing the single border between two frames as shown above, you must set the frameborder attribute to both of the adjacent frames. If you only set it on one of the frames, depending on the browser you view it in, it will either thin the frame down a bit or do nothing at all.

Opera has been given a "partial" pass as it does not entirely honor frameborder="0" even when set to both frames; there is still a visible gray border, albeit thinner and lighter than if the border was set to be on.
