Accordion with background change on panel-heading on click

- October 11, 2018

Hi I am using Bootstrap-3 and I need to change the background-color of class .panel-heading to any other color.

When I click on accordion the background color of that particular accordion should be changed..

Here is the code with solution.=>

CSS ==>

 
    .panel-group .panel {
        border-radius: 0;
        box-shadow: none;
        border-color: #EEEEEE;
    }

    .panel-default > .panel-heading {
        padding: 0;
        border-radius: 0;
        color: #212121;
        background-color: #FAFAFA;
        border-color: #EEEEEE;
    }

    .panel-title {
        font-size: 14px;
    }

    .panel-title > a {
        display: block;
        padding: 15px;
        text-decoration: none;
    }

    .more-less {
        float: right;
        color: #212121;
    }

    .panel-default > .panel-heading + .panel-collapse > .panel-body {
        border-top-color: #EEEEEE;
    }

/* ----- v CAN BE DELETED v ----- */
body {
    background-color: #26a69a;
}

.demo {
    padding-top: 60px;
    padding-bottom: 60px;
}

.highlight{background: #ff0 !important; transition: 2s ease all;}
