Can Iframes Really Fill the Entire Screen Height with a 100% Height Setting?

Can an Iframe Occupy the Entire Screen Height with 100%?

The article addresses the question of whether iframes with a height of 100% are universally supported across browsers. The usage of a specific doctype and the inclusion of an iframe code are both part of the inquiry.

Iframe Height Support

According to the response, utilizing framesets is an option. However, if iframes are preferred, two code examples are provided to ensure the iframe occupies the remaining page height. This includes setting "height" and "width" to "100%" within the iframe's style attribute.

Scrollbar Management

The article also addresses the issue of scrollbars. Although the code specifies "scrolling=no," the scrollbars still appear in Firefox. To address this, the overflow settings in the parent body element should be set to "hidden" while ensuring the iframe has a height and width greater than 100% or uses an absolute position with dimensions occupying the entire screen.

Additional Notes

To completely conceal scrollbars, the height and width of the iframe can be set to 150%, effectively pushing the scrollbars off the page. This ensures the iframe fully occupies the available screen area without visible scrollbars.

This solution is widely supported by major browsers, including IE, Firefox, and Safari. However, it's important to note that the w3 HTML standard doesn't officially endorse iframes with 100% height in pure doctypes.
