There are three new attributes of the IFRAME element that help improve the security and design of your iframes. This article explains what they are for and how they can be used.

Linking in Iframes and Frames
When you add links to documents that are inside frames, you can choose where they should open—inside the current frame, inside the window holding the frame, or inside a completely new window.

HTML5 has made HTML frames obsolete. This was primarily done because screen readers and other accessibility browsers do not handle frames well at all. But if you write in HTML 4.01, you can still use frames. This two page article discusses the benefits (page 1) to HTML frames and the drawbacks (page 2). If you are considering using HTML frames you should be aware of all the facts surrounding them so that you make a decision that is good for your readers and your site.
