<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<form class="form-inline">
  <div class="input-group">
    <input type="text" class="form-control input" placeholder="How may we help you?">
    <div class="input-append">
      <button type="button" class="btn"><i class="fas fa-search"></i></button>
    </div>
  </div>
</form>

Answer 1

I think you wanna do something like this

1. On Focus- Change color of form background to #fff(White)
2. On unfocus - Change form background to transparent

$('input').focus(function () {
    $('form').css({
        'background-color': '#fff',
        'transition': 'background-color 1s ease-out'
    });
});

$('input').blur(function () {
    $('form').css({
        'background-color': 'transparent'
    });
});

$(document).ready(function(){
   $("input").focus(function(){
       $('form').css({
          'background-color': '#fff',
          'transition': 'background-color 1s ease-out'
           });
    });

    $('input').blur(function(){
        $('form').css({
           'background-color': 'transparent'
            });
    });
});

Try this.
