Improves website load time by removing redundant resource loading and optimizing critical rendering path. Adds mobile support with tap-to-continue functionality and fully responsive layout.

Changes

Eliminated duplicate CSS loading

  • Removed 3 duplicate <link> tags at document end (main.css, ellipse.css, wave.css loaded twice)
  • All stylesheets now load once in <head>

Optimized font loading

  • Added preconnect hints for Google Fonts domains (saves ~100-300ms DNS/connection time)
  • Moved Google Fonts from CSS @import to HTML <link> with display=swap
  • Prevents render-blocking and FOIT

Non-blocking JavaScript execution

  • Externalized inline script to js/main.js (enables browser caching)
  • Added defer to script tags (scripts execute after DOM parse, maintain document order)

Mobile optimization

  • Added viewport meta tag
  • Tap-to-continue fallback: Made the enter screen clickable/tappable for mobile users without physical keyboards
  • Mobile hint: Added "or tap here" text that displays only on mobile/touch devices
  • Optimized responsive layout:
    • Reduced all element sizes for optimal mobile fit
    • Text sizes: 2.8vw for main text, 2vw for labels (compact and readable)
    • Wave animations: 28vw containers (properly sized for mobile screens)
    • Radar circles: 15vw with thinner borders (40vw wrapper)
    • Repositioned all elements to prevent overlap and fit within viewport
    • Fixed overflow issues by adjusting element positions
  • Hover effect on enter button for improved user experience

Please add a fallback to enter key when viewing on mobile and there's not keyboard available. Also make the next screen mobile friendly.

Added in commit 0d13668. The website now shows "or tap here" hint on mobile devices and the enter box is clickable/tappable. Also added responsive CSS for better mobile display with appropriate font sizes.

Fixed in commit 06150ff. Improved the mobile layout with:

  • Repositioned all elements (waves, radar circles, text) to fit properly on mobile screens
  • Scaled elements appropriately using viewport units
  • Increased text sizes for better readability (4.5vw for main text, 2.5vw for smaller text)
  • Fixed overflow issues by adjusting positions (garbage text, receiving/sending labels)
  • Made radar circles and wave animations properly sized for mobile

Improved Mobile Main Screen:

I'm sorry, but it looks worse on mobile now. Try reducing the size of the objects and text so it fits better
