An id on a <kbd> tag assigns an identifier to the element.
The identifier must be unique across the page.
An id attribute on 3 <kbd> elements.
CTRL + C is used to copy content,
CTRL + X is used to cut content, and
CTRL + V is used to paste content.
<p>
<kbd id="ctrl-c">CTRL + C</kbd> is used to copy content,<br />
<kbd id="ctrl-x">CTRL + X</kbd> is used to cut content, and<br />
<kbd id="ctrl-v">CTRL + V</kbd> is used to paste content.<br />
</p>
The id attribute assigns an identifier to the <kbd> element.
The id allows JavaScript to easily access the <kbd> element.
It is also used to point to a specific id selector in a style sheet.
Tip: id is a global attribute that can be applied to any HTML element.
<kbd id="identifier" />
| Value | Description |
|---|---|
| identifier | A unique alphanumeric string. The id value must begin with a letter ([A-Za-z]) and may be followed by any number of letters, digits ([0-9]), hyphens (-), underscores (_), colons (:), and periods (.). |
A <kbd> tag with a unique id.
Clicking the button will display the text inside the element.
CTRL + C is used to copy content.
<p><kbd id="mykbd">CTRL + C</kbd> is used to copy content.</p>
<br />
<button onclick="show();">Show content</button>
<script>
let show = () => {
let kbd = document.getElementById("mykbd");
alert("Content = " + kbd.innerHTML);
}
</script>
The id attribute assigns a unique identifier for the <kbd> element.
Clicking the button calls JavaScript which locates the <kbd> using the id.
Finally, the content of the <kbd> is displayed in an alert box.
