What it does
Frontend Mentor provides web-development challenges with designs or briefs, solution submission and code-review features.
Pick a challenge whose difficulty matches your current HTML and CSS skills. Build against its design or brief, then compare the result with the requirements before submitting. The site supports community review and AI review, with different limits for free and Pro members. Its supplied project constraints are useful when an open-ended blank page makes practice hard to start. You may use your chosen stack. Free members currently receive one AI review per month; Pro adds a review on every submission and a skills profile.
Strengths
- Designs and briefs give practice projects concrete requirements
