Cart Styling

[torres-diego]

We need the items that are added to cart and appear on the cart.html page to be styled.

this is what it looks like:

Style in whichever way fits the scheme for the app.

Here are the divs and id's where the menu items are inserted:

```

  <div class="totals">Total Cost: $<span id="total-cart"></span></div>
  <div class="totals">You have <span id="item-count"></span> items in your cart</div>
  <button class="delete-all" id="clear-cart">Delete All</button>

these are the classes for the add/ minus button, they are written in the cart.js file:
<button class='sub-item'>
<button class='plus-item'>

[torres-diego]

the ul id is #show-content

these are the plus/minus button classes button class='sub-item' minus button button class='plus-item' plus button
