Create Responsive Accordion (Source Code)

An Accordion is a section that contains a header and description with open and close functionality. Basically, the description of the accordion is in hidden status and we have to click on the header section to get a description. Every accordion’s header has its own description. The accordion can be made of various text content, for eg FAQ.

Let’s have a quick look at the given image of our accordion. There is a total of four tabs with different beautiful background colors. In every tab, there are different questions and icons. As you have seen on the second tab, it is in the opened state and the other three are in the closed state. If you click on every tab it will open and close also If one is in opened condition and you clicked on another tab the previously opened tab will automatically close and, the tab you have clicked will be opened.

All the HTML CSS and JavaScript code that I have used to create this accordion has been uploaded below before you jump into the source code, I would like to explain some basic points of this video tutorial on the accordion.
