When you make a fastpage from fastai, if you want to change the style, you have to go to the _sass folder but by default it is known as minima. I tried to change the minima but it resulted in an error message

This was the error message I got when I changed the theme to something else, in this case, I did minimal instead of minima

In the above image we see that everything worked except the Jekyll build because it did not recognize that and it was not able to deploy it on the website so the actual appearance of the fastpage did not change

After choosing a theme, I decided to choose slate and afterwards I realized my website did not work. The style was completely different and I liked it but one issue I found was that when I clicked on a post, I couldn’t click the title to go back to the page and the home page was completely different and the posts’ format was different as well
