Ah, not necessarily size down, just being conscious of how different elements relate to each other on the canvas.
A common way to deal with different screen sizes is the use of containers to keep your content within a defined size. Webflow has a pre-configured Container component that is 940px wide, this allows the design with responsiveness in mind.
Templates are good and have their place. As mentioned, unexpected results come when we don’t understand how the Template has been structured or created (use of padding/margins, rows/columns or flexbox) all have their place, but still need to have an understanding of how it all hangs together.
Recommendation - Always depends on what your desired outcome is. If you want to learn more about how to use Webflow with this project, then persevere. If you need a website for your business, then the motivation is entirely different. Your time costs money. And if trying to figure out how to create a site (or modify a Template) takes you away from your core business, then probably not the best use of your time or resources. (Let alone the increased stress/anxiety of feeling like your banging your head against the wall!)
There are Webflow experts (https://experts.webflow.com) that can help create your site for you, I don’t know what the costs would be but you could approach to find out. If you have a clear understanding of what you want your site to do, then it can be structured in such a way that will allow you to add content in the future. (Perhaps by then you may have a better hold on how to use Webflow?)
Others have put out a general call on these forums, saying that they are looking for a developer and got responses that way.
I’ll have a look at your Footer to see what’s happening and post back to you.
Hang in there buddy
