Responsive Accordion Design using HTML, CSS, and Javascript

Hello readers, today in this blog you'll learn how to create a responsive accordion design using HTML, CSS, and Javascript. In our previous blog, we saw how to create custom context or right-click menu design using HTML, CSS, and Javascript. Now it's time to create a responsive accordion design. I've also shared many projects related to Javascript. So don't forget to check here.

An accordion is an element used in the graphical user interface. Nowadays almost every website uses an accordion for answering frequently asked questions (FAQ).

In this design [Responsive Accordion Design] we have an accordion in the middle of the page as you can see in the image above. When you click on an item then a class will be added by javascript and the accordion will open with a smooth transition. The background color of the header part will be changed. If you're feeling difficulty understanding what am I trying to say? So you can check source code and preview as well.

Preview is available here.
