CSS Width Property

The width property in CSS defines the width of an element, allowing control over its horizontal size within the layout.

The width property can be applied to various HTML elements. Here's an example:

<html>
<head>
<style>
  div {
    width: 300px;
    background-color: lightblue;
  }
</style>
</head>
<body>

<div>This div has a defined width of 300 pixels.</div>

</body>
</html>
