Easy to create and maintain. You can also create a table without a border that's the size of your Web page, then add text and images to the table's columns and rows to give your page a consistent and tidy appearance. When used with graphics or pre-formatted text, tables may force your visitors to scroll horizontally. With frames, you can offer your visitors ease of navigation. Frames are ideally suited for sites whose contents frequently change.
Frames cause pages to download slower.
You Can't use the Back button with frames. Some browsers won't let visitors print a framed page. Frames can crash computers if you have your page split up into too many different frames. You can't bookmark pages that use frames. Frames are difficult to create.
