Yes, of course, but Iframe <frameborder> attribute is also obsolete. If I still use <frameborder> how to create a line between the two frames that is shown in the previous example? Should I use CSS {border-left: } property?

A few days ago I decided to learn CSS. I found the following example on one page that uses frames.

If a frame and frameset attributeს are deprecated in HTML 5_ How to get the exact same result?
