Master frontend skill by cloning these sites🎉 1. Netflix🎯 https://www.netflix.com/in/login?nextpage=https%3A%2F%2Fwww.netflix.com%2Fbrowse When logged in Netflix is a pretty simple design. Horizontal rows, galleries, with a big featured banner. 2.Hulu🎯 https://www.hulu.com/welcome Just like Netflix, the logged in experience in Hulu is pretty similar. Has a large featured banner, and basically rows of movies or tv shows with every few rows having a featured section. 3. Apple 🎯 https://www.apple.com/ You'll know what I mean by "big block" design. Apple does this well. It's clean, intuitive and pretty straight forward. If you break everything down into smaller components, you'll see how easy it would be to implement the design. 4. Airbnb🎯 https://www.airbnb.co.in/?locale=en&_set_bev_on_new_domain=1638253270_ZWVmZDNiNGY3OWJh Airbnb is such a beautiful website! The assets are amazing. Break this design down into smaller components, and you'll see how it's just a bunch of big rows and small rows. Blocks either spanning multiple columns, or the entire row. 5.SpaceX🎯 https://www.spacex.com/ Super easy design. SpaceX is basically multiple fullscreen images with fade up content and a link section. 6. NVIDIA🎯 https://www.nvidia.com/en-us/ Another easy, but professional looking design. Just a banner, grid layout and rows. 7.Razer🎯 https://www.razer.com/ A mix of a large home banner, full page featured sections, and big box design. Have fun with this sick color scheme! 8.Salesforce🎯 https://www.salesforce.com/in/?ir=1 Another great website to polish your css skills. A mix of banners, rows, columns, reverse columns, big box design, but also has featured list, multiple call to actions, and fun images. 9. Adobe🎯 https://www.adobe.com/ Another big box design. But also features some cool background gradients. 10. Microsoft🎯 https://www.microsoft.com/en-us/ Features a modal, big banners, multiple featured sections, big call to action. Pretty straight forward, but professional looking design. 11. Blockchain🎯 https://www.blockchain.com/ Learn about blockchain while you clone this one. This design incorporates a few more difficult design concepts. It also features a big banner, call to actions, gradient effects, but also has big box designs as links and dynamic accordions. So not only does the accordion tab drop more content below it, it changes the image beside it! You probably have a tool of choice for this 🤔 12. Paypal🎯 https://www.paypal.com/us/home Features a big banner, call to action, and reverse rows. Straight forward, but effective design. 13. Slack 🎯 https://slack.com/intl/en-in/ Slack features a fun homepage banner. In the banner is a toast banner, a call to action, a Google sign in button, and a row of icons featuring companies that use Slack. The rest of the layout is a simple grid system with a typical reverse row design. Minimal animations, like hover effects. 14. Discord🎯 https://discord.com/ Probably my favorite looking website on the list. It has fun vibrant colors, a minimalistic homepage banner featuring a call to action, reverse row grid layout and a nice big featured section. 15. Amazon🎯 https://www.amazon.com/ The king of e-commerce. This is a straight up "show off" mockup. If you can nail Amazons design, your frontend dev design skills are up to industry standard. Features a slightly more complex grid layout, with content spanning one or more rows and columns. Has a search bar in the navigation. Also has recommended section, hover effects, carousels, etc. Have fun with this behemoth! 16. PlayStation🎯 https://www.playstation.com/en-us/ Playstation. com has a nice large homepage banner featuring a slide show with a nice fade in effect. You can code this from scratch, or use your favorite library.
