How to use Stylus and Babel code?

There are some nice Html websites which uses Stylus and Babel Codes.
I wanted to implement them to my website. But here it goes: How to?
Usually you can implement css-code in Html with the

tag. The javaScript code you can add with tag. There is no tag for stylus or babel as i looked around the web. You can however change the stylus code ( which is called scss ) with an converter to css. For babel I couldnt find anything. Now i thought i just need to load up the files in my file manager and link the 'src-code' to the html widget. But "wix" doesnt allow this. No Js, css, or other files. Well, here I am now: Does anyone had the same issue and solved it? Or does anyone know how to get around this?

You can easily add html code to your website by having a read of the following links and all of the sub links on those pages too.

If you are adding it all to your page as just one piece of code, then you will need to include the html, js and css parts all in one code.

Otherwise, some html codes will require a piece of code to be placed in the header of your website and the rest of it to be placed on your page, which you can easily do by adding a custom tool in your tracking and analytics.
