Another day, another TIL post. Today I just found out that you cannot put an iFrame inside an iFrame and expect it to work. You cannot nest it. I found out about this from a half-finished website I visited earlier. Their homepage has an iframe with the homepage inside it. I noticed that the iFrame inside the iFrame was empty and when I searched for it, it really is not possible.
I've also started reading the Pragmatic Programmer earlier and I'm learning a lot. I'm just 30 pages in but it's already interesting.
That's it for today's TIL!
