Your problem is that you’re using absolute sizing for your elements, for example, your slider has a width of
768px instead of something like
100vw. You’re also using margins to position your items instead of things like Flexbox.
You still need an understanding of responsive design to work with Webflow, and they do a pretty good job at teaching you literally everything you need to know in their ultimate web design course which will take about 5-6 hours to complete: https://www.youtube.com/watch?v=O5TdnuUhIgs&list=PLPmnoMVpkxfgvx6K9WCv-zlbIksh7yJd-
Also, using images for all of your content is a terrible idea. Your website will load slowly depending on the image sizes. You’re using PNG instead of JPG which is almost unacceptable unless you need the transparency or absolute quality for some reason. (Photography website, modelling, etc).
Everything other than your backgrounds can be created with some styling and text, which can then be read by good and they can then show your website to others.
I started with Webflow 2 days ago, and this is what I have so far;
It works perfectly on all devices.
I do not have a web-development background either.
You can also check out the vehicles page, which uses the CMS system to dynamically get data about a vehicle I’ve entered.
