CSS Styling Lab
🎨 If HTML is the skeleton, CSS is the clothes! Click buttons for color, background, font size, weight, and alignment to see CSS code generate line by line and change text instantly. Press undo to reset both code and screen—learn hands-on that code creates the screen! 📦 In the Box Model tab, move sliders for padding, border, and margin to see how every element is a box with three layers. 🎯 Finish with 5 challenge levels—match properties to target (it tells you how many differ). This app was made with code too · Remix it to add more colors!
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?
