        </div>

        <div class="total-price">$349</div>
      </div>
    </div>

CSS:

* {
  box-sizing: border-box;
}

html,
body {
  width: 100%;
  height: 100%;
  margin: 0;
  background-color: #7EC855;
  font-family: 'Roboto', sans-serif;
}

Great, now let’s make our Shopping Cart to be 750×423 and style it to look nice. Notice that we are using flexbox, so we set it to display flex and make the flex direction column, because by default the flex direction is set as row.

.shopping-cart {
  width: 750px;
  height: 423px;
  margin: 80px auto;
  background: #FFFFFF;
  box-shadow: 1px 2px 3px 0px rgba(0,0,0,0.10);
  border-radius: 6px;

  display: flex;
  flex-direction: column;
}

Next, let’s style the first item, which is the title, by changing the height to 60px and giving it some basic styling, and the next three items which are the shopping cart products, will make them 120px height each and set them to display flex.

.title {
  height: 60px;
  border-bottom: 1px solid #E1E8EE;
  padding: 20px 30px;
  color: #5E6977;
  font-size: 18px;
  font-weight: 400;
}

.item {
  padding: 20px 30px;
  height: 120px;
  display: flex;
}

.item:nth-child(3) {
  border-top:  1px solid #E1E8EE;
  border-bottom:  1px solid #E1E8EE;
}

Now we’ve styled the basic structure of our shopping cart.
Let’s style our products in order.

The first elements are the delete and favorite buttons.
I’ve always loved Twitter’s heart button animation, I think it would look great on our Shopping Cart, let’s implement it.

.buttons {
  position: relative;
  padding-top: 30px;
  margin-right: 60px;
}
.delete-btn,
.like-btn {
  display: inline-block;
  Cursor: pointer;
}
.delete-btn {
  width: 18px;
  height: 17px;
  background: url("delete-icn.svg") no-repeat center;
}

.like-btn {
  position: absolute;
  top: 9px;
  left: 15px;
  background: url('twitter-heart.png');
  width: 60px;
  height: 60px;
  background-size: 2900%;
  background-repeat: no-repeat;
}

We set class “is-active” for when we click the button to animate it using jQuery, but this is for the next section.

.is-active {
  animation-name: animate;
  animation-duration: .8s;
  animation-iteration-count: 1;
  animation-timing-function: steps(28);
  animation-fill-mode: forwards;
}

@keyframes animate {
  0%   { background-position: left;  }
  50%  { background-position: right; }
  100% { background-position: right; }
}

Next, is the product image which needs a 50px right margin.

.image {
  margin-right: 50px;
}

Let’s add some basic style to  product name and description.
.description {
  padding-top: 10px;
  margin-right: 60px;
  width: 115px;
}

.description span {
  display: block;
  font-size: 14px;
  color: #43484D;
  font-weight: 400;
}

.description span:first-child {
  margin-bottom: 5px;
}
.description span:last-child {
  font-weight: 300;
  margin-top: 8px;
  color: #86939E;
}

Then we need to add a quantity element, where we have two buttons for adding or removing product quantity. First, make the CSS and then we’ll make it work by adding some JavaScript.

.quantity {
  padding-top: 20px;
  margin-right: 60px;
}
.quantity input {
  -webkit-appearance: none;
  border: none;
  text-align: center;
  width: 32px;
  font-size: 16px;
  color: #43484D;
  font-weight: 300;
}

button[class*=btn] {
  width: 30px;
  height: 30px;
  background-color: #E1E8EE;
  border-radius: 6px;
  border: none;
  cursor: pointer;
}
.minus-btn img {
  margin-bottom: 3px;
}
.plus-btn img {
  margin-top: 2px;
}

button:focus,
input:focus {
  outline:0;
}

And last, which is the total price of the product.

.total-price {
  width: 83px;
  padding-top: 27px;
  text-align: center;
  font-size: 16px;
  color: #43484D;
  font-weight: 300;
}

Let’s also make it responsive by adding the following lines of code:

@media (max-width: 800px) {
  .shopping-cart {
    width: 100%;
    height: auto;
    overflow: hidden;
  }
  .item {
    height: auto;
    flex-wrap: wrap;
    justify-content: center;
  }
  .image img {
    width: 50%;
  }
  .image,
  .quantity,
  .description {
    width: 100%;
    text-align: center;
    margin: 6px 0;
  }
  .buttons {
    margin-right: 20px;
  }
}

That’s it for the CSS.

JavaScript

Let’s make the heart animate when we click on it by adding the following code:

$('.like-btn').on('click', function() {
   $(this).toggleClass('is-active');
});

Cool! Now let’s make the quantity buttons work.

$('.minus-btn').on('click', function(e) {
    e.preventDefault();
    var $this = $(this);
    var $input = $this.closest('div').find('input');
    var value = parseInt($input.val());

    if (value > 1) {
        value = value - 1;
    } else {
        value = 0;
    }

  $input.val(value);

});

$('.plus-btn').on('click', function(e) {
    e.preventDefault();
    var $this = $(this);
    var $input = $this.closest('div').find('input');
    var value = parseInt($input.val());

    if (value < 100) {
        value = value + 1;
    } else {
        value =100;
    }

    $input.val(value);
});
