The id Attribute

The HTML element's unique id is specified by the id property. It is employed to distinguish one piece on the page from another. This is helpful if you need to reference an element in JavaScript or need to style a particular one.

Key Points:

  • Uniqueness: Throughout the HTML page, every id value must be distinct.
  • Targeting: JavaScript can manipulate the DOM and CSS can target styles with ease.

Example:

<div id="mainContent">
    <p>This content is uniquely styled and accessed.</p>
</div>

The id in CSS can be used to apply certain styles:

#mainContent {
    padding: 20px;
    border: 1px solid black;
}
