Auto-Adjusting Iframe Dimensions to Fit Content

Problem:

How can an iframe's width and height be automatically adjusted to precisely fit its contained content? This adjustment should be possible after the iframe has loaded.

Solution:

To achieve this, an event action is required to handle changes in the dimensions of the body within the iframe. Here's the solution:

In the above code:

• The resizeIFrameToFitContent() function sets the width and height attributes of the iframe based on the scroll width and height of its contained body.
• The DOMContentLoaded event listener is used to adjust the iframe's dimensions after the iframe has loaded.
• The optional additional code (commented out) can be used to resize all iframes on the page.
