IFRAME needs a SRC attribute to tell it where to get its contents.

Normally the source attribute will be "http://...something...", but could
also be "ftp://...something..." or "gopher://...something...". Basically
these are different URL-schemes, which indicate to the browser it should
recieve the file in different ways: using Hyper-Text Transfer Protocol,
using File Transfer Protocol, using Gopher, etc.

In this example, I've chosen to use "data:...something...". This tells the
browser it should retrieve the file by continuting to read the URL.

In this case, it will read:

Blah <b>blah</b>
