I would like to change the default loading bar in an html export to something like this:

I don’t know how to write an html/css code, so I thought I could replace it.
I hope someone can help me with this.

I think you should take a look at this page to get a starting point: Customizing the Web export HTML page — Godot Engine (3.0) documentation in English

Thank you, but I don’t understand HTML and CSS good enough to code this with the documentation.
