I’ve attached a screen shot of what the HTML and CSS looks like when you inspect any bubble website.
As you can see, all of the elements have “bubble” references - making it very clear that this website/app was built in bubble.
Here is more information on why minification is important:
Webflow gives it’s customers the option to Minify the HTML, CSS and JS natively in the settings. Bubble.io does not.
I’m trying to figure out if anyone has successfully minified their apps in any way.
