Converting Bootstrap Tabs Into Accordions In Mobile View using CSS only
This is really simple to make the regular Bootstrap tabs fully responsive and mobile-friendly only using CSS and a bit of jquery code. The CSS breakpoint automatically changes the Bootstrap tabs component into a collapsible and expandable accordion interface when the screen size is smaller than a specific breakpoint.
The interesting thing is only CSS media query can change tabs into an accordion
for this, we have already a tabs button and accordion header/button and the content area is single so that we don't need to write content multiple times,
When we change screen size from desktop to mobile version then tabs button will hide, and accordion header will be visible, and that's it,
and jquery function is changing plus icon into minus icon only.
There is a lot of jquery plugin available on the internet for doing the same, But we are not using the plugin.
First, create index.html

Then we need CSS for work full process and design
.all-tab-img img {
padding-bottom: 20px;
}
.all-tab-img img:nth-last-child(2) {
padding-bottom:0;
}
.ourwork-tab-wrap{
padding: 50px 0px;
position: relative;
}
.ourwork-tab-wrap .nav-tabs {
display:none;
border-bottom: none;
}
.ourwork-tab-wrap .nav-tabs .nav-item {
background: #427fad;
margin-right: 10px;
margin-bottom: 0px;
}
.ourwork-tab-wrap .nav-tabs .nav-link{
border: none;
border-top-left-radius: 0px;
border-top-right-radius: 0px;
color: #fff;
}
.ourwork-tab-wrap .nav-tabs .nav-item.show .nav-link, .nav-tabs .nav-link.active{
background: #54bbca;
color: #fff;
}
@media(min-width:768px) {
.ourwork-tab-wrap .nav-tabs {
display: flex;
}
.ourwork-tab-wrap .card {
border: none;
}
.ourwork-tab-wrap .card .card-header {
display:none;
}
.ourwork-tab-wrap .card .collapse{
display:block;
}
}
@media(max-width:767px){
.ourwork-tab-wrap .tab-content > .tab-pane {
display: block !important;
opacity: 1;
margin-bottom: 10px;
}
.ourwork-tab-wrap .card-header {
background: #427fad;
color: #fff;
border-bottom: 1px solid rgba(0,0,0,.125);
}
.ourwork-tab-wrap .card-header h5 a{
background: #427fad;
color: #fff;
border-bottom: none;
text-decoration: none;
font-size: 16px;
display: block;
}
.ourwork-tab-wrap .card-header h5 a i {
float: right;
padding-top: 5px;
}
.ourwork-tab-wrap .card-body {
border: 1px solid #427fad;
}
.ourwork-tab-wrap .card-header h5 a:hover {
color: #fff;
}
}
Then we need some jquery function for changing plus-minus icon while clicking on tabs or accordion button
$(document).ready(function(){
// Add minus icon for collapse element which is open by default
$(".collapse.show").each(function(){
$(this).prev(".card-header").find(".fa").addClass("fa-minus").removeClass("fa-plus");
});
// Toggle plus minus icon on show hide of collapse element
$(".collapse").on('show.bs.collapse', function(){
$(this).prev(".card-header").find(".fa").removeClass("fa-plus").addClass("fa-minus");
}).on('hide.bs.collapse', function(){
$(this).prev(".card-header").find(".fa").removeClass("fa-minus").addClass("fa-plus");
});
});
