Picture in line with text coding. Quick help appreciated! (trying to share my site tomorrow) : )

Site URL: https://www.nicholasdimaria.com/bio

Squarespace won't allow me to drag an image into the top left corner of the text when editing in mobile view. I would like the picture to occupy half of the screen next to the text in mobile. This works in desktop view, but in mobile view it just stacks the image above the text. The picture is what it looks like in desktop (and in the style I would like it to look on mobile.

(I have similar problems across the website, so a TEMPLATE of code for how I could fix problems like this would be more useful than just a direct fix. I am comfortable finding ID's or page section numbers) Thank you!
