I feel like they should allow me to try their designer without having to sign up. I'd recommend they split test that against their current onboarding flow.
Check out https://www.flexboxgame.com/ to experience the Webflow UI while playing a Flexbox game. Gives you a sense of the controls that Webflow exposes without signing up.
Hmm, I can't seem to get past Level 1 in the flexbox game. I'm probably doing something wrong, but the circle I'm supposed to drag to the outline doesn't want to move.
You aren't supposed to click and drag it. You use the css flexbox attributes (see right-hand sidebar) to move it over the goal.
