The Post Grid does not reduce in size

Hi

I am using this plugin and is working fine on my laptop with adequate borders both on the left and the right (with standard 100% browser resolution). It is appearing okay even on mobile but when I access the site on a smaller laptop (with again 100% resolution), the post grid does not proportionately reduce and occupies the entire width and infact looks bigger and there are almost no borders left on either side.

In case there is any css code or solution for this, please help me out.
I am using OceanWP with elementor page builder.

Thanks
