I need help for git page on Github

Hi, I am new to GitHub. I would like to use Git hub pages to host my HTML and CSS file on GitHub. I am having a problem. This is my site link https://github.com/Kijimu7/Kisshing_dog but it has an error because I have a folder on the reposit. I have HTML and other files in the folder. Am I able to host the files inside the folder?
Thank you!

You will want to either create a new repo or move the all the files to outside the inner folder. Also, you should rename your HTML page from card.html to be index.html.

Then follow the steps on https://pages.github.com/ click ‘Project site’ then ‘Start from scratch’ and then start from step 4. (which is: Click on the Settings tab and scroll down to the GitHub Pages section. Then select the master branch source and click on the Save button.)

Thank you for the reply. So, git hub is one project for one reposit?
Thank you so much, v-lai I could host in git hub page and now it is live.
