Attributes

An attribute is extra information attached to an element, written inside its opening tag:

<a href="https://gdwithgd.com/">A link</a>

href is the attribute and the URL is its value. Without it, a link element has no idea where to send anyone.

The rules

• Attributes go in the opening tag only, never the closing one.
• Values go in quotes.
• An element can have as many as it needs, separated by spaces.

The two you’ll use forever

class and id don’t change how anything looks by themselves. They’re labels, so that CSS and JavaScript can find a specific element later. You’ll be using class constantly by the end of the next chapter.
