Rules for coding HTML keygen elements
Make sure you understand the difference between a tag and element and are familiar with the definitions of namespace and other HTML terms.
- Code the keygen element where phrasing content is expected, usually inside a form element.
- Begin the keygen element with a starting <keygen> tag. The element name uses lower case letters and should be in the HTML namespace, which it will pick up automatically from the
xmlns
attribute on the <html> tag. - If the field is for a form that can be submitted but is outside that form element, include a
form
attribute referencing the form the keygen is to be associated with. - Include any other attributes on the <keygen> tag as appropriate.
- Inside the keygen element, between the starting
<keygen>
tag and the ending</keygen>
tag, code the inner HTML phrasing content. - End the keygen element with a matching
</keygen>
closing tag.
<keygen/> Content Model
Contents of the keygen element
Content: Empty. All properties are coded using attributes.
Since the <keygen/>
tag is a void element, it is not allowed to have any content, even HTML comments and therefore should always be coded as a self-closing standalone tag, ending with the delimiters />
rather than just >
(<keygen .../>
).
