Try this:
$('input').on('focus', function () {
$(this).parent().addClass('active');
});
.example {
margin-top:30px;
border:1px solid gray;
border-radius:4px;
padding:15px;
}
.example >i {
margin-right:10px;
}
.search-input {
border: none;
width: 90%;
}
.search-input:focus{
outline: none;
}
.example.active {
border-color: #80bdff;
}
.search-box .input-group-addon {
background: none;
}
.search-box input {
border-left: none;
}
.search-box.active .input-group-addon {
border-color: #80bdff;
