HTML <link> id Attribute

An id attribute on a <link> element.

<head>
  <link id="tutorial" rel="stylesheet" type="text/css" 
        href="/tutorial/style.css">
</head>

Using id

The id attribute assigns an identifier to the <link> element.

The identifier must be unique across the page.

The id allows programmatic access to the <link> element.

Tip:  id is a global attribute that can be applied to any HTML element.

More Examples

A <link> tag with a unique id.
Clicking the button will display the href value of the link.

<head>
  <link id="mylink" rel="stylesheet" type="text/css" href="/tutorial/style.css">
</head>

<button onclick="show();">Show link href</button>

<script>
  let show = () => {
    let element = document.getElementById("mylink");
    alert("Href = " + element.href);
  }
</script>

Code explanation

The id attribute assigns a unique identifier for the <link> element.

Clicking the button calls JavaScript which locates the <link> using the id.

Finally, the href value of the <link> is displayed in an alert box.
