title: In CSS how do you change font size of h1 and h2
body: <p>In a WordPress twenty eleven theme. I want to change the size of headings
  When I wrap my headings around h1 and h2 tags as follows</p>
  <pre><code>&lt;h1&gt;My h1 heading &lt;/h1&gt;
  &lt;h2&gt; My h2 heading &lt;/h2&gt;
  </code></pre>
  <p>The font size of heading in the theme I am using is almost same as content's font except that they are bold. So my headings are not quite prominent.</p>
  <p>I guess I would need to change something in the CSS file. Please advise what exactly in need to put in.</p>
