When You Type
⌨️ You learned button clicks, now let's type! Type in the box and watch the screen react instantly — counting letters, changing colors, or growing bigger. Try replacing input with change to see how it waits until you finish typing! In 🔍 What to Type?, read the code to solve the puzzle, and in ✅ Validation, set rules like "4+ letters to pass" and test them with the 🧪 button like a real coder. Built with code · Remix to create your own input box!
When You Press a Button
👆 Your page comes alive at last! Pick "When (click) + What (background)" to build real working code — tap the button below and watch the box change live! Switch to double-click, and a single tap won't budge it! 🔢 With Memory Buttons, try adding 1, doubling, toggling 🌞🌙, growing bigger, or showing 🎉 on click 3. You'll see firsthand why variables are so useful! 🎮 In Remote Control, assign different tasks to 3 buttons. This app was made with code too — ready to remix and create your own buttons?
HTML Tag Playground
🏷️ How does code change what's on screen? Pick a word and press tag buttons — <b> makes it bold and <mark> highlights it! With code above and the preview below, see instantly what changes. 🧱 Next, build a page: stack titles, paragraphs, lists, dividers, and buttons to create a real webpage. 🔍 Finish with 5 code-reading quizzes — guess the screen just by reading the code. This app was built with code too. Want to remix and add more tags?
