You’re maybe skipping an important step of the design process: pen and paper. There’s a lot of complexity on your site: different panels, and a pretty large default container that needs to be handled with care for the viewport values in between it width and 960px.
Depending on what you design on paper, you’ll build an appropriate structure to address all the responsive goals.
So in order to help you build the best structure, I think we need a sketch of your page for those different viewport width:
- what the page should look like at viewport width = 1920
- at 960
- for tablet portrait
- for smartphone landscape
- for smartphone portrait
I don’t think Webflow is overlooking advanced techniques to address responsivity: this isn’t Webflow’s role to address all the challenges here, but it’s your role to design them and make sure the structure you’re going to build allows for building your responsive strategy. But I agree, this is the challenging part. Difficulty added because you’re working on an e-comm site, where you can’t neglect any of the elements of the page.
