Explain the difference between iframe and frame in HTML with examples

I don't know if you have used the frameset attribute in your project. I used the frameset attribute in the production of an online customer service system last year. Because the customer service system needs a fixed layout, with one piece on the top, one piece on the bottom, and so on, I used frameset and frame at that time. After I played around with these attributes, I understood the difference between iframe and frame. Because before this, I generally didn't use frames in my projects, and if I did, I would use iframes.

Let’s talk about the specific differences below! The following points are summarized.

1. Frame cannot be used alone without frameSet, but iframe can;

2. Frame cannot be placed in body;

The following can be displayed normally:

The following cannot be displayed normally:

On the contrary, if the iframe is placed under the frameSet attribute, it must be placed in the body

3. iframe is an HTML tag and can be used anywhere in HTML, but frame cannot.

The frame must be nested in the frameSet and cannot be used in tags such as table.

4. The height of the frame can only be controlled by frameSet; the iframe can be controlled by itself, not by frameSet

5. If more than two iframes are used on the same page, they can be displayed normally in IE, but only the first one can be displayed in Firefox. Using more than two frames can work normally in both IE and Firefox.
