Frames
A web page, as you must have notice before, can be splitted into several parts where each part will be a different HTML file.

So a page called ex_frames.htm, can be splitted into left and main frame for example.
To do this:

- Open a new document
- Insert --> Frames --> Left

Now the page is splitted into two columns. Both the left and the right column will load two different HTML files. We can call left.htm the left frame and main.htm the second one.

Have a look at this example to understand how it will look like and at this example to understand how it would look like if we made a top and main frame.

My advice is to avoid frames as they often cause troubles in different browsers and rather use dynamic layouts with tables and divs./
