I'll help you create an iPad emulator using HTML, CSS, and JavaScript. Here's the initial setup:

I'll modify the styles to make the iPad emulator cover the full screen while maintaining the aspect ratio:

The changes include:

1. Using viewport units (vmin) for responsive sizing
2. Added media queries for landscape/portrait orientation
3. Made the iPad frame scale to fit the screen while maintaining aspect ratio
4. Adjusted all measurements to be relative to viewport size

Here's a MacBook emulator that will adapt to full screen:

Key features:

1. Responsive design using vmin units
2. Realistic MacBook proportions (16:10 screen)
3. macOS-style menu bar and dock
4. Blur effects for transparency
5. Working clock in the status bar
6. Hover effects on app icons
7. Keyboard and trackpad representation
