Is there a possibility to undo all of the changes done to my style.css ?

Thanks a lot! Appreciate it :)

You can always choose what you want to give on this page: https://generatepress.com/ongoing-development

Let me know if you have any other questions!

Oh, just one more thing, is there a way to center all of the current and future blog post titles ?

On the single posts or on the blog (that shows all of the post excerpts)?

On the blog page, where it shows all of the posts.

.blog .entry-header,
.archive .entry-header {
      text-align: center;
}

Hi Tom,

Could you share the css for the single blog post as well. I was able to center the post excerpts but when I click to actually go the post it is not center.

Thanks

Give this a go:

.single .entry-header {
      text-align: center;
}

Buy the addons! 1. they're awesome value for money and 2. Tom deserves it! Oh and leave the man a great review!
