title: How to change the design for cart item quantity in woocommerce?
body: <p>I am working on cart.php template. I am changing the design. I can't find where I could change the design of cart item quantity field. For example add : after the word quantity? There is the filter woocommerce_cart_item_quantity but I don't understand how it can help me. I just enclosed this field into div and that is all.</p>

  <p>Template given by woocommerce:</p>
  
  <pre><code>&lt;div class="product-quantity delivery" data-title="&lt;?php esc_attr_e( 'Quantity', 'woocommerce' ); ?&gt;"&gt;
      &lt;?php
  if ( $_product-&gt;is_sold_individually() ) {
      $product_quantity = sprintf( '1 &lt;input type="hidden" name="cart[%s][qty]" value="1" /&gt;', $cart_item_key );
  } else {
      $product_quantity = woocommerce_quantity_input( array(
          'input_name'    =&gt; "cart[{$cart_item_key}][qty]",
          'input_value'   =&gt; $cart_item['quantity'],
          'max_value'     =&gt; $_product-&gt;get_max_purchase_quantity(),
          'min_value'     =&gt; '0',
          'product_name'  =&gt; $_product-&gt;get_name(),
      ), $_product, false );
  }
  
  echo apply_filters( 'woocommerce_cart_item_quantity', $product_quantity, $cart_item_key, $cart_item );
  ?&gt;
  &lt;/div&gt;
