title: Internal styling in React
body: <p>I would have assumed that this would have been easy for me to find but I can't find it anywhere. In HTML you can style all your tags (headers, paragraphs, img, etc.) like this:</p>
  
  <pre><code>&lt;style&gt;
    body {background-color: powderblue;}
    h1   {color: blue;}
    p    {color: red;}
  &lt;/style&gt;
  </code></pre>
  
  <p>How do I do the same in React? I want to reference all <code>p</code> tags and some <code>custom</code> ones from classes.</p>
