Why make such a list?
Often more than not, when I visit a developer's portfolio, they all showcase the same projects. Calculators, Recipe Finder, To-do, these are all great projects to get into web development, but employers are not looking for these sort of projects any more. The list below will showcase unique ideas that you can build out and showcase on your portfolio.
With Frontend Mentor, you're getting the following in the zipped file:
✔️JPEG design files for mobile & desktop layouts
✔️ Style guide for fonts, colours, etc
✔️ Optimized image assets
✔️ README file to help you get started
✔️ HTML file with pre-written content
with the added option of a Sketch file, but for a subscription of $8/mo, it also includes access to all premium templates/challenges. You can also submit your code for other members of the community to view and review.
A smaller selection of challenges but still a viable one nonetheless. Piccalilli has only 8 challenges but the solutions are posted for everyone to view. The fact that the solutions are available is great as reference to people still new to web development, but it's always important to keep in mind that there is no one solution in web development.
This one is a bit of a shameless plug, but I'd like to include it, it might help someone out there. This is a personal project of mine.
✔️ Figma files
✔️ Assets (Icons and images)
✔️ Design exported in PNG for Deskto, mobile, and tablet
✔️ README file
This one is paid, but it provides you with the following:
✔️ 30 challenges with assets for practicing
✔️ 30 code solutions
✔️ 1st solution free
✔️ Technical hints and advice
5- Build Dribbble Shots
This one is my favorite, it honestly is. Dribbble is notorious for having designs that aren't that usable, but there are still some established designers on the platform who know what they're doing. I believe building out Dribbble shots will challenge your CSS layout skills as well as your design skills.
This one is old, but still a great way to showcase your CSS skills. The idea here is that everyone is provided with the same HTML file, but it's up to you to use CSS to make it your own. You can see all the submitted designs on CSS Zen Garden's website, you'll see some amazing stuff.
That's it, feel free to comment below places I might have missed and I'll add it to this article right away.
