HTML Checking for Large Sites
Rocket Validator automatically checks your pages on the W3C Validator.
HTML issues tagged as non-empty.
The href
attribute on the link
element must not be empty.
An <iframe>
element allows to embed an HTML document inside another HTML document, and its src
attribute is indicated the source URL of the embedded web page. The src
attribute is a required attribute, so it cannot be blank.
Example:
<iframe src="https://example.com/map.html"></iframe>
