title: css width and height doesn't work
body: <p>I have the following code, but width/height of spans doesn't really work.</p>
  
  <p>HTML</p>
  
  <pre><code>&lt;div id="amount" class="ch_field3"&gt;
  &lt;span id="ch_minus"&gt;-&lt;/span&gt; 3 &lt;span id="ch_plus"&gt;+&lt;/span&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>CSS</p>
  
  <pre><code>.shop_chekout_item{min-width: 100%; float: left;}
  .shop_chekout_item .ch_field3{display: block;float: left; width: 20%;}
  
  .shop_chekout_item #ch_plus,.shop_chekout_item #ch_minus{
  background: #ccc; 
  width:  20px; /*no effect...*/
  height: 20px; /*same here :(*/
  cursor: pointer}
  </code></pre>
