Posts not fully responsive, get cut off on mobile devices

Hi!

I’m using a Zerif Lite child theme with custom css. I did follow the guide on https://docs.themeisle.com/article/14-how-to-create-a-child-theme when creating the child theme.

I noticed today when finalizing my page that posts are not fully responsive. They scale down accordingly when i decrease the window size from Desktop to Tablet. But they don’t scale on mobile devices.

Instead the text is cut off to the right and unable to read on mobile devices.

I don’t have any widgets enabled and the theme is up to date (v1.8.4.5).

Why are the posts cut off?

Thanks!
