How To Get Width Of Element In Css

In this blog post, we will explore how to get the width of an element using CSS. This can be useful when you need to adjust the size of an element based on its content or for responsive design purposes.

Use the width Property

The most straightforward way to set or get the width of an element in CSS is by using the width
property. By default, the width of a block-level element is set to auto, which means the
element will take up as much width as its parent allows. To explicitly set the width of an element, you can
use different units, such as pixels (px), percentages (%), or even viewport units (vw).

For example, let’s say we have a div element that we want to set to a width of 300 pixels:

    div {
        width: 300px;

Using max-width and min-width Properties

If you want to set a range for the width of an element, you can use the max-width and
min-width properties. These properties allow you to set the maximum and minimum width an
element can have, providing more control over the element’s sizing.

For example, let’s say we want our div element to have a minimum width of 200 pixels and a
maximum width of 500 pixels:

    div {
        min-width: 200px;
        max-width: 500px;

Get the Width of an Element Using JavaScript

While CSS is great for setting the width of an element, it doesn’t provide a direct way to get the width of an element. For this, we can use JavaScript. The most common method for getting the width of an HTML element is by using the offsetWidth property. This property returns the width of an element, including padding, border, and scrollbars if present.

For example, let’s say we have a div element with an ID of “myDiv”:

    <div id="myDiv">
        Content goes here

To get the width of this element using JavaScript, we can use the following code:

    var myDiv = document.getElementById("myDiv");
    var myDivWidth = myDiv.offsetWidth;
    console.log("Width of myDiv:", myDivWidth);

This code will log the width of the “myDiv” element to the console.


Getting the width of an element in CSS can be easily done using the width, max-width, and min-width properties. However, to get the actual width of an element on the page, you’ll need to use JavaScript and access the offsetWidth property of the element. With these techniques, you can efficiently control and retrieve the widths of elements on your web page.
