With the Glitch-made Markdown to HTML generator, how would you use your own CSS file?
Are you referring to markdown-webpage? If so on line 11 in the server.js file (https://glitch.com/edit/#!/markdown-webpage?path=server.js:11:2) you can edit it to include the styles inline in the header, for example see: https://glitch.com/edit/#!/luxuriant-archeology
Awesome, thank you!
Is it possible to use an external css file though?
Yep! Same way you normally would except you include the full URL:
<link rel="stylesheet" href="https://www.example.com/styles.css">
