DevMonkey teaches web development by helping you change real pages from your first lesson. Work through 220 focused lessons across HTML, CSS, responsive design, JavaScript and DOM interaction. Every concept is paired with a practical activity: predict what the browser will do, fix a bug, reorder code, fill a gap or build the solution yourself. WRITE CODE AND SEE IT LIVE Edit HTML, CSS and JavaScript in a native coding workspace, then inspect the page in a real WebKit preview. DevMonkey checks the document the browser actually built, so feedback connects directly to the result on screen. BUILD A PORTFOLIO Start with one free playground project or choose from 10 substantial capstones, including a portfolio, landing page, gallery, quiz, todo app, restaurant site, invitation, product documentation, habit tracker and data dashboard. Pro projects export as standard ZIP files that open in any modern browser. REMEMBER WHAT YOU LEARN Short review sessions schedule HTML, CSS and JavaScript concepts for practice. Track lesson progress, XP and your learning streak without creating an account. LEARN ANYWHERE The complete curriculum, reference library, code runner and lesson checker work offline.
