There are three things here:
1) standard frames have fallen out of favor. search engines have trouble reading them and styles have moved on since then
2) there is something called an iframe. that's different. but ignore that for now, since it's likely too far beyond your current coding skills and might not be what you are looking for anyway.
3) there are containers like this: <div>put your stuff in here</div>
I think what you are asking is how you can make your webpage have different sections of information. You do that with divs. You can do that with tables also, but that has fallen out of favor.
