title: Injecting CSS or JS into Chrome on Android
body: <p>Is there a way to inject (non-malicious) JavaScript (or CSS) statements into Chrome on Android whenever a matching URL is loaded?</p>
  
  <p>Basically, I'd like to modify how some sites look.</p>
  
  <p>One example would be <code>m.facebook.com</code>:<br>
  I'd like to inject something like:</p>
  
  <pre><code>#header: {position:fixed; margin-top:-2px}
  #root:{margin-top:40px}
  </code></pre>
  
  <p>Unfortunately, Google doesn't extend the plugins API for the mobile platform!</p>
  
  <p>Any thoughts?</p>
