Color Values
HTML me colors RGB, HEX, HSL, RGBA, aur HSLA values se bhi specify kiye ja sakte hain.
RGB, HEX, aur HSL se background color set karne ka example:
RGBA aur HSLA me alpha channel add hota hai (transparency ke liye).
Example:
HTML RGB and RGBA Colors
RGB color value RED, GREEN, aur BLUE light sources ko represent karta hai. RGBA color value, RGB ka extension hai jisme ek extra Alpha channel (opacity) hota hai.
RGB Color Values
HTML me color ko RGB value se specify kiya ja sakta hai is formula se:
rgb(red, green, blue)
Har parameter (red, green, blue) ki value 0 se 255 ke beech hoti hai.
Iska matlab total possible colors:
256 × 256 × 256 = 16,777,216 colors
Examples:
- rgb(255, 0, 0) → Red (red highest, baaki 0)
- rgb(0, 255, 0) → Green
- rgb(0, 0, 0) → Black
- rgb(255, 255, 255) → White
Mix Value:
rgb(255, 99, 71)
RGBA Color Values
RGBA, RGB ka extended version hai jisme Alpha channel hota hai jo opacity define karta hai.
rgba(red, green, blue, alpha)
Alpha value 0.0 se 1.0 ke beech hoti hai:
- 0.0 → Fully transparent
- 1.0 → Fully visible
Examples:
- rgb(255, 99, 71, 0)
- rgb(255, 99, 71, 0.2)
HTML HEX Colors
Hexadecimal color is format me specify hota hai:
#RRGGBB
Yaha:
- RR → Red
- GG → Green
- BB → Blue
Ye sab hexadecimal integers hote hain jo color ke components define karte hain. 00 se ff ke beech hoti hain numbers.
Examples:
- #ff0000 → Red (red highest = ff, baaki 00)
- #00ff00 → Green
- #000000 → Black (sab 00)
- #ffffff → White (sab ff)
HTML HSL and HSLA Colors
HSL ka full form hai Hue, Saturation, Lightness. HSLA, HSL ka extended version hai jisme Alpha channel (opacity) add hota hai.
HSL Format
- Hue → 0–360 (0=Red, 120=Green, 240=Blue)
- Saturation → 0% (gray) to 100% (pure color)
- Lightness → 0% (black) to 100% (white)
Example:
HSLA Format
Syntax:
- Alpha → 0.0 (transparent) to 1.0 (solid)
