Accessibility

Modern browsers have very good accessibility support for iframes, and this can be further enhanced to aid users navigating with assistive technology, such as screen readers, by using the title attribute on an <iframe> to label its contained content.

Having a title attribute allows screen readers to announce the purpose of the iframe without requiring users to navigate into it. This saves time and reduces confusion, especially on pages with multiple <iframe> elements or interactive content like video or audio.

Automated Title Attribute

Where iframes are missing the title attribute, iframe-resizer will automatically set it using the text contained within the <title> element of the iframe’s content. This ensures the title attribute is always up to date and accurately reflects the page currently displayed within the iframe.

For example:

<!-- Without title -->
<iframe src="example.html"></iframe>

<!-- With title -->
<iframe src="example.html" title="Example Content"></iframe>

By automating this process, iframe-resizer ensures that your iframes are accessible without requiring additional manual effort.
