Feature this Post functionality not working

Not able to set Feature Post for the blog post in Home page. Even I set it as a favorite one, it doesn’t appear in home page of my blog. The recently published post was automatically taken as a Feature Post.

I’m using Casper theme. Any suggestions/advice would be much appreciated.

Thanks.

Casper doesn’t by default do anything with featured posts other than mark them as featured. Did you want it to show up first? You can use routes.yaml to do that. I’m on my phone, but take a look at the docs for how to change the order of your posts in the routes.yaml file.

Could you share me how do I achieve that in routes.yaml?
