Horizontal scrolling using Flexbox

If you create websites, chances are you have been asked to create a horizontal scrolling component. It is extremely easy to implement this using just a few lines of Flexbox. Let me show you how.

Project Layout

We need to create a container that will contain all the images that we want to scroll. Here is the code:

<div class="container">    <img src="images/bhutan1.jpg" alt="Bhutan">    <img src="images/bhutan2.jpg" alt="Bhutan">    <img src="images/bhutan3.jpg" alt="Bhutan">    <img src="images/bhutan4.jpg" alt="Bhutan">    <img src="images/bhutan5.jpg" alt="Bhutan">    <img src="images/bhutan6.jpg" alt="Bhutan">    <img src="images/bhutan7.jpg" alt="Bhutan"></div>

Styling the Project

Next step is to add styling so that the container scrolls horizontally. To do this I make the container display as flexbox. In addition I am setting the overflow-x value to auto. Here is the style:

.container {    display: flex;    overflow-x: auto;}

This is what the horizontal scroll looks like:

The initial version of our horizontal scroll

That does provide our requirement of a horizontal scroll area. I am not satisfied with how it looks. There are three things I want to change:

  • Add white space between the images
  • Get rid of the horizontal scrollbar
  • Place the scroller in the middle of the screen

The images are touching. Let’s add some white space between them. Here is the CSS for this:

.container img {    margin-right: 15px;}

Next I want to get rid of the horizontal scrollbar which I can do with this code:

.container::-webkit-scrollbar {    display: none;}

The last change that I want to do is to center the scrolling are in the center of the screen. By default, the hight of the html is the height of the elements. I need to make the height to be 100% of the viewport. Flexbox provides a way to center items with the align-items setting. To use this functionality, I am going to convert the body to display as flexbox. Here is the code that I am going to add for the body:

body {   display: flex;   align-items: center;   height: 100vh;}

With these changes, here is what our final horizontal scroll area looks like.

Conclusion

It is very easy to create a horizontal scroll area using flexbox. Thanks for reading.
