css – 使div的内容可滚动

我正在使用wordpress与woocommerce创建eshop. Woocommerce有一部分名为mini-cart.php它是客户的实际购物车.但是我需要这个购物车最多占整个网站高度的60％,我需要购物车内容可滚动.这很容易,但我需要的第二件事是从滚动中排除按钮和总数.我尝试了很多方法,但它永远不会奏效.这是我使用的代码：

<div class="cart active">
  <div class="cart-wrapper">
    <h1 class="widget-title"> </h1><div class="widget_shopping_cart_content"><div class="cart-product-list">
    <ul class="cart_list product_list_widget ">
      <li><a href="http://autoflex.zone42.sk/obchod/2x-stabilizator-predna-naprava-porsche-911-od-09-1997/">
          <img src="http://autoflex.zone42.sk/wp-contenthttp://img.558idc.com/uploadfile/2013/10/2x-stabilizátor-predná-náprava-Porsche-Boxster-od-09.1996-90x90.jpg" class="attachment-shop_thumbnail wp-post-image" alt="2x stabilizátor predná náprava Porsche 911 od: 09.1997" height="90" width="90">
                    2x stabilizátor predná náprava Porsche 911 od: 09.1997
          </a>
          <p class="quantity">1 × <span class="amount">50,90€</span></p>
     </li>
  </ul>
</div><!-- end product list -->    
<p class="total"><strong>Medzisúčet:</strong> <span class="amount">50,90€</span></p>  
    <div class="buttons">
        <a href="http://autoflex.zone42.sk/kosik/" class="button">
            <div class="cart-buttons">
                <div class="cart-buttons-padding">
                    Zobraziť košík →                </div>
            </div>
        </a>
        <a href="http://autoflex.zone42.sk/pokladna/" class="button checkout">
            <div class="cart-buttons">
                <div class="cart-buttons-padding">
                  pokladňa →                </div>
            </div>
        </a>
    </div>


</div>

这是CSS：

.cart.active{
    max-height: 60%;
    margin-bottom: -25px;

    transition: max-height .5s .2s;
    -ms-transition: max-height .5s .2s;
    -moz-transition: max-height .5s .2s;
    -webkit-transition: max-height .5s .2s;
}
div.facebook:hover, div.mail-us:hover, div.move-up:hover, div.cart-total.hoverOn:hover{
    right: 150px;
}
div.cart-total.hoverOn{
    transition: all .5s, width .5s .5s;
}
div.cart-total.hoverOff{
    transition: all .5s, width .2s;
    right: 150px;
    width: 279px;
}
.cart-product-list{
    overflow-y: auto;
}

那么如果我只想要ul(cart_list)可滚动,我该怎么办？而且我还希望整个div名称购物车活跃​​在整个网站的最高60％？谢谢你

ul.cart_list {
 overflow: scroll;
}
