I want a program that looks over an #HTML document and its #CSS stylesheets, and applies the stylesheets' rules as `style` attributes on the HTML elements in the document.
Meaning this:
<html>
<style>p:first-child { margin-top: 0 }</style>
<p>First paragraph</p>
<p>Second paragraph</p>
</html>
Translates into this:
<html>
<p style="margin-top: 0">First paragraph</p>
<p>Second paragraph</p>
</html>
Is that a thing?
