Outline Color

The outline-color property is utilized to define the color of the outline.

Color can be specified using:

Name: Indicate a color name, such as “red”
HEX: Specify a hexadecimal value, like “#ff0000”
RGB: Define an RGB value, such as “rgb(255,0,0)”
HSL: Specify an HSL value, like “hsl(0, 100%, 50%)”
Invert: Utilize color inversion (ensuring the outline remains visible irrespective of the background color).

The subsequent example displays various outlines in different colors. Additionally, observe that these elements feature a narrow black border within the outline.

Example

p.ex1 {
border: 2px solid black;
outline-style: solid;
  outline-color: red;
}

p.ex2 {
  border: 2px solid black;
outline-style: dotted;
outline-color: blue;
}

p.ex3 {
  border: 2px solid black;
  outline-style: outset;
  outline-color: grey;
}

HEX Values

The color of the outline can alternatively be specified using a hexadecimal value (HEX).

Example

p.ex1 {
outline-style: solid;
outline-color: #ff0000; /* red */
}

RGB Values

Alternatively, RGB values can be used to specify the outline color.

Example

p.ex1 {
outline-style: solid;
outline-color: rgb(255, 0, 0); /* red */
}

HSL Values

HSL values are also an option for specifying the outline color.

Example

p.ex1 {
outline-style: solid;
outline-color: hsl(0, 100%, 50%); /* red */
}
