Can I store a .css text file on the back-end and use the HTML <script src="urlToTxtFile.css"></script> to load the custom CSS?

I have a webpage that displays a table that requires custom CSS.

I’m moving the site to Wix. I understand that Wix does not provide access to CSS, only to JavaScript.

I’m wondering whether, using Velo, I can’t store the CSS text file on the back-end and then use the HTML tag to load the CSS.

If so, would you provide an example of what the code would look like to store retrieve it?

Bumping thread… does any one have an update on this?
