How to remove tag

[admin]

I have a pre tag which is causing the css to display with too much whitespace.
How do I remove it with css?

        <!-- page-title -->

            <h1 class="page-title" itemprop="name">Checkout</h1>

        <!-- /page-title -->

        <div class="page-content entry-content" itemprop="articleBody">

        **<pre>**<div class="woocommerce">
       <div class="woocommerce-info">Have a coupon? <a href="#" class="showcoupon">Click here to       enter your code</a></div>

     <form class="checkout_coupon" method="post" style="display:none">

The css reads

pre, xmp, plaintext, listing {
display: block;
font-family: monospace;
white-space: pre;
margin: 1em 0px;
}

how do I change whitespacere?
