Attributes

Attributes add extra information to an element, written inside the opening tag as name/value pairs.

Attribute syntax

<a href="https://example.com">Visit site</a>
    ↑attribute name  ↑attribute value

The attribute value is wrapped in quotation marks. Most elements can take several attributes at once, each separated by a space.
