Hex Code
Hex
is short for hexadecimal
, which is a way to represent color values in base-16.
Basic Structure
A hex code starts with the #
symbol, followed by six hexadecimal characters (0-9, A-F).
Examples:
#FFFFFF
→ white#000000
→ black#FF0000
→ red
Color Composition
The six characters of a hex code are grouped into pairs, each representing red (R), green (G), and blue (B) respectively.
For example, in the hex code #FF5733
:
-
FF
represents the intensity of the red color. -
57
represents the intensity of the green color. -
33
represents the intensity of the blue color.
Usage
You can use hex codes in CSS to specify the color of an element.
div { background-color: #ff5733; }
The above code sets the background color of the div
element to #FF5733
.
Short Hex Code
Sometimes, you can use a three-character hex code to represent colors. This is useful when each color component has the same value.
Examples:
#FFF
→#FFFFFF
(white)#000
→#000000
(black)
Follow the highlighted parts of the code as you input it.
