Sidebar widgets problem

I have just started my adventure with Astrid, it is a lovely theme! But I have a problem with sidebar widgets. All of them, are shown vertically, like recent posts on my website. On your demo they are shown horizontally. How can I change that? Or what affected it?

Thank you for your support.

Hello @pihova, I’m not sure what is your issue.

Can you please provide some explanatory screenshots to illustrate your issue?

You can upload screenshots to your WordPress Media Library and share a link, or you can use one of the online screenshot services.

Kind Regards, Roman.
