help with grouping

i'm very amateur on Wix, tho proud of the 40 page site i have created and works great. I got some feedback from people who say that some text is showing up blocked by the photo next to it. in the Editor it looks fine and on my desktop and phone it looks fine. Perplexity AI tells me some devices may display things differently unless you group, e.g., text and photo. I tried to do this, click the photo, hold shift, click the text box, but there is no "group elements" option. can't find it anywhere. can anyone help me?
