How can I make my Wix site automatically adjust to different screen sizes?

Hi everyone, I just started building my website on Wix (link: https://marketing21756.wixsite.com/my-site-5). On desktop it looks fine, but on smaller screens and mobile the layout breaks and elements don’t resize properly.

What is the best way in Wix (Editor vs. Wix Studio) to make my site automatically responsive — so the width and layout adapt to all screen sizes without me manually fixing each element?

Any step-by-step advice or best practices would be super helpful. Thanks! 🙏
