Query:
Is iframe height=100% universally supported across browsers? When using XHTML1 as the doctype, will an iframe with a height of 100% occupy the remaining page height (excluding a 50px fixed height frame at the top)? Additionally, how can scrollbars be completely hidden while automatically setting the iframe's height?
Response:
While framesets may be employed, the provided examples demonstrate alternative methods for implementing a full-screen iframe with a height of 100%:
<body>
Another option:
<body>
To suppress scrollbars using these approaches:
<body>
Alternate method:
<body>
In these examples, the parent is assigned overflow: hidden to conceal scrollbars. By enlarging the iframe to 150% of its original dimensions, the scrollbars are forced beyond the page's boundaries. As a result, the body's lack of scrollbars precludes the iframe from extending beyond its bounds on the page. This strategy effectively conceals the iframe's scrollbars while allowing for full-width display.
