Hex Code

Hex is short for hexadecimal, which refers to a base-16 numbering system used to represent color values.

A hex code starts with a # followed by six hexadecimal characters (0-9, A-F).

Examples:

• #FFFFFF → White
• #000000 → Black
• #FF0000 → Red

The six characters in a hex code are grouped into pairs, representing Red (R), Green (G), and Blue (B).

For instance, in the hex code #FF5733:

• FF represents the intensity of red.

• 57 represents the intensity of green.

• 33 represents the intensity of blue.

In CSS, hex codes can be used to specify the color of elements.

Copy
div {
  background-color: #ff5733;
}

The code above sets the background color of the div element to #FF5733.

Sometimes, a 3-digit hex code is used to represent colors. This is useful when each color component has the same value.

Examples:

• #FFF → #FFFFFF (White)

• #000 → #000000 (Black)

Type the emphasized parts of the code as instructed.
