Can't see site on GitHub pages. What is the problem?

Question

GitHub

Hello.
My repository with uploaded files of a multi-page site.
However, this link: IgorichYak.github.io/Portfolio-Site does not find anything, 404 error.
What is the problem ? maybe additional steps are needed?

Answer 1

Option 1. In this repository, create a "gh-pages" branch and push the code there. GitHub pages only take code from the "gh-pages" branch. Then your site will be opened by the link IgorichYak.github.io/Portfolio-Syte (by the way, it's correct to write "site")
Option 2. Create a repository "IgorichYak.github.io" and put the layout in the master branch. For repositories like "username.github.io", GitHub pages only take code from the "master" branch. Then you will get a shorter address in the browser IgorichYak.github.io

Slider. Written on Bootstrap CDN Works locally as it should. I sent it to github, it is displayed there as pictures https://urbina67.github.io/Start/. And the grid is broken. Ideally, it should be like on the insert. What could be the reason?
