User Agent String
Example: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 Chrome/120.0.0.0 Safari/537.36
What it reveals:
- Browser name and version

It helps them know if you need mobile or desktop layout.
Screen Resolution
Example: 1920 x 1080 pixels
What it reveals: Your physical screen size in pixels.
Websites use this to serve appropriately sized images.
It helps them avoid sending 4K images to small screens.
Viewport Size
Example: 1536 x 720 pixels
What it reveals: Your browser window size (not full screen).
This is what responsive design actually uses.
It changes when you resize your browser window.
Color Depth
Example: 24-bit (16.7 million colors)
What it reveals: How many colors your screen can display.
Modern screens all support millions of colors.
Older or specialized hardware may have less.
Language

Websites use this to show content in your language.
You can change this in browser settings.

Languages: en-US
Interpretation: High-end Windows desktop.
Website can serve large images safely.
Example 2: Mobile Safari User
User agent: Contains “iPhone” and “Safari”
Screen: 390 x 844 (small screen)
Viewport: 390 x 700 (after address bar)
