title: Computed height different from specified height
body: <p>While making a button on my website, I was trying to draw inspiration from the search button at www.google.com.</p>
  
  <p>So, using google chrome as the browser, I went to www.google.com, right clicked on the "Google Search" button and selected "Inspect Element" option. I saw that the button element has the class "lsb" and css specifies a height of 30px for an element of this class. This specification has not been overridden by another statement (or else chrome would tell me so). Still, when I look at the computed value, I see that the height is 43px, rather than 30px.</p>
  
  <p>So, I am wondering, what is causing this increase in the height of the element?</p>
