title: Animation or transition just using style attribute inside a tag
body: <p>It is possible?<br>
  I mean this:  </p>
  
  <pre><code>&lt;div style="?css animation?"&gt; Content &lt;/div&gt;
  </code></pre>
  
  <p>It can be any tag, or maybe triggering the animation or transition from other tag.
  This question is because I will like to use animations and transitions in a web app, but this app just let me use css included in the style tag attribute.</p>
  
  <p>Pseudo clases I guess are out of the question so I can not trigger transitions, neither I can use javascript, so onmouseover or similar kind of stuff are out of the question.</p>
  
  <p>Animations on the other hand needs their keyframes settings, and I can not set keyframes inside a style tag.. (or can I?). I read something similar here:
  <a href="https://css-tricks.com/animate-to-an-inline-style/" rel="nofollow">https://css-tricks.com/animate-to-an-inline-style/</a>
  But I guess it would not work for what I am asking.</p>
  
  <p>Not sure if there is a hack to import a css from an attribute or just achieve animations in chrome browsers (another thing, I have not access to the head section of the html).</p>
  
  <p>Yeah I know, it seems mission impossible, I was just wonder in case there is some kind of trick to achieve this even if the animation is very limited.
  Thanks for your time.</p>
