Hey @Whatchamacallit
Welcome to the Webflow Community!
Absolutely, the sites built up with Webflow show up beautifully on all browsers and devices, as long as you’ve designed with responsiveness in mind of course.
Check out the designer showcase to see for yourself just what is possible, and try them out on a few browsers.
Of course it’s always advisable to test your site out as much as you can before launching to iron out any bugs or design issues, and you can host on a Webflow domain while you do this.
The Webflow University is loaded with useful information and well worth taking a look if you haven’t already.
If you get stuck at all, just reach out here on the forums, the community really is a major part of what makes Webflow so special for so many people, just don’t forget to share your read only link if you can when asking for project help.
If you’re sticking around then you can always introduce yourself in this thread too
And always remember there’s no such thing as a stupid question… What is obvious for some, others are oblivious to 
Good luck and enjoy!
