Browser Support
The autofocus attribute is supported in all major browsers, except Internet Explorer and Firefox.
Note: Even if the autofocus attribute works in Safari, Safari does not support the <keygen> element.
Definition and Usage
The autofocus attribute is a boolean attribute.
When present, it specifies that the <keygen> element should automatically get focus when the page loads.
Differences Between HTML 4.01 and HTML5
The <keygen> tag is new in HTML5.
Syntax
<keygen autofocus="autofocus" />
Note: The autofocus attribute is a boolean attribute, and can be set in the following ways:
- <keygen autofocus>
- <keygen autofocus="autofocus">
- <keygen autofocus="">
