Do <style> tags work in Markdown?

Question

I'm writing a Github README.md file, and i have diferent tables. The contents are different, so table width is different too.

I want, at least the first column to be of fixed width, so i tried adding this before all the tables in the Markdown file:

<style>td:nth-child(odd){width:200px}</style>

Surprisingly that is working in my editor preview, but when committed to github, the text appears with the style tags stripped, and no style is applied.

My questions is if it's possible on github, and id it is, how do i do it.

Solution

Just tested it myself.

<style>
#foo {color: red}
</style>

<p id="foo">foo</p>

<p style="color: blue">bar</p>

The above rendered to:

#foo {color: red}
<p>foo</p>

<p>bar</p>

GitHub strips style tags and attributes preventing you from changing the style on their pages. This is probably for security reasons. If you could inject css into GitHub pages, you could easily launch a phishing attack.
