How Can I Achieve Full-Screen iFrame Content with 100% Height and Handle Browser Compatibility Issues?

Using iFrames for Full-Screen Content with 100% Height

If you're considering using iFrames to display full-screen content with a fixed height of 100%, there are some browser compatibility issues to consider, as well as techniques for hiding scrollbars.

Browser Compatibility

Unfortunately, iframe height=100% is not fully supported in all browsers, particularly when using the XHTML 1.0 Transitional doctype. While it may work in some modern browsers like Chrome and Firefox, it's not guaranteed to work consistently across all browsers.

Hiding Scrollbars

To completely hide scrollbars in an iframe, you can use the following CSS styles:

overflow: hidden;
overflow-x: hidden;
overflow-y: hidden;

Using Frameset as an Alternative

Instead of using iFrames, you could consider using a frameset to achieve full-screen content. This method is more reliably supported in most browsers. Here's an example:

<frameset rows="100%,*">
  <frame src="header.html">
  <frame src="main.html">
</frameset>
