title: How to change the default size of <h1>...<h7> tags in Android WebView?
body: <p>I'm specifying some HTML text like this in the strings.xml file of my Android app:</p>
  
  <pre><code>&lt;string&gt;
  
      &lt;h4&gt;title&lt;/h4&gt;&lt;br/&gt;
             some text
  &lt;/string&gt;
  </code></pre>
  
  <p>1) How can I change the size of the text for the h4 tag? I've changed the default text size of my app in styles.xml to 23sp, but for the h4 tag I want it to be for example 28sp.</p>
  
  <p>2) Is it possible to change the text size for buttons and textviews in the theme for the whole app? I want all of my textviews to have 23sp size and buttons to have 26sp.</p>
