How to align a Flexbox container to the center using JavaScript?

To align a Flexbox container to the center using JavaScript, we first need to select the container using a DOM manipulation method such as querySelector. Next, we need to set the container’s CSS properties to “display: flex” and “justify-content: center”. This will center-align the items within the container horizontally.

Flexbox is a layout mode in CSS3 that allows you to align and distribute elements on the page. It can be used to create a main navigation bar or lay out a photo gallery, etc. Flexbox is a powerful tool that can make your web page layout more flexible and responsive.

There are multiple ways to center a Flexbox container using JavaScript -

• The most common method is to set the margin-left and margin-right properties to "auto". This will cause the Flexbox container to be centered within its parent element.

• Another method is to set the width of the Flexbox container to "100%" and then set the "justify-content" property to "center". This will cause the Flexbox container to be centered within its parent element.

The following code will use JavaScript to center the Flexbox container. The container must have a defined width and flex-direction must be set to row.

First, we get the element with the ID "container" -

var container = document.getElementById("container");

Then, we set the container's style.flexDirection to "row" -

container.style.flexDirection = "row";

Finally, we set the container's style.justifyContent to "center" -

container.style.justifyContent = "center";

Example

      <script> 
         var container = document.getElementById(&quot;container&quot;);
         container.style.display ='flex';
         container.style.flexDirection = 'row';
         container.style.justifyContent = 'center';
