I was thinking about this and thought it should be possible to make a converter for old websites

so that

<style>
h1 {
    color:#FFF;
}
</style>

<h1>Hello</h1>

becomes

<h1 class="text-white">Hello</h1>

It wouldn't have to be perfect but it would be great for anyone that wants to convert a big old website to this.. could save lots of time and should help adoption rate of this awesome project.

Thoughts? Any idea on why this wouldn't be easy/possible?
