How to set Github Pages image path?

Question

GitHub

I host the project on Github Pages on the gh-page branch (this is the second project and you can't follow the main path).
https://poslavsky.github.io/multiStepsForm/public/
Everything works, but for some reason the pictures have the path https://poslavsky.github.io/img/promo1.jpg
to the root, not to multiStepsForm. Therefore, they are not displayed.
Maybe you have come across and have ideas how to fix it easier?

Answer 1

Replace absolute paths
on
or

background: #FF6E20 url(/multiStepsForm/public/img/promo1.jpg) no-repeat;
