Attributes are additional information provided by HTML elements.
- HTML elements can set attributes
- Attributes can add additional information to the element
- The attributes are generally described in the opening tag
- Attributes always appear in the form of name/value pairs, such as name=”value” .
HTML links are defined by <a> tags. The address of the link is specified in the href attribute :
<a href = " https://hackerthink.com "> This is a link </a>
HTML attributes commonly reference attribute values
The attribute value should always be enclosed in quotation marks.
Double quotes are the most commonly used, but there is no problem with using single quotes.
HTML tip: use lowercase attributes
Attributes and attribute values are not case sensitive.
However, the World Wide Web Consortium recommends lowercase attributes/attribute values in its HTML 4 recommendations.
The new version of (X)HTML requires lowercase attributes.
