Mockupea is a 3d book configurator that is running in the browser. It was made using three.js for 3d graphics, html, css and javascript. You can see it here (not working on mobile for now): https://mockupea.com/. Source: over 1 year ago

Tailwind has a mass of ready-made UI libraries and components, so it's not that when you start working in it you always have to build everything from scratch. For example; https://shuffle.dev/tailwind. Source: about 2 years ago

Just take note that to get code you'll need to buy subscription: shuffle.dev/tailwind. Source: about 2 years ago

If it's too pricey for you, than you may like this option, also with read-made components https://shuffle.dev/tailwind. Source: over 2 years ago

Haha, yes CSS is sometimes a PITA. If you are looking for ways to build landing pages there are luckily a lot of no-code tools out there already: https://typedream.com/ https://shuffle.dev/ or if it should be more customizable https://webflow.com/. Source: over 2 years ago

It’s „custom designed“ but I heavily rely on the amazing CSS framework TailwindCSS and their pre made components called TailwindUI. There’s also https://shuffle.dev/tailwind which I have used for some other pages. It’s a nocode tool and even builds on Tailwind. Let me know if I can help further. Source: over 2 years ago
