outline-width

Utilities for controlling the width of an element's outline.

Class	Styles
`outline`
`outline-width: 1px;`

| | outline-<number> |

outline-width: <number>px;

| | outline-(length:<custom-property>) |

outline-width: var(<custom-property>);

| | outline-[<value>] |

outline-width: <value>;

Use outline or outline-<number> utilities like outline-2 and outline-4 to set the width of an element's outline:

outline

outline-2

outline-4

<button class="outline outline-offset-2 ...">Button A</button><button class="outline-2 outline-offset-2 ...">Button B</button><button class="outline-4 outline-offset-2 ...">Button C</button>

Prefix an outline-width utility with a variant like focus:* to only apply the utility in that state:

Focus the button to see the outline added

<button class="outline-offset-2 outline-sky-500 focus:outline-2 ...">Save Changes</button>

Learn more about using variants in the variants documentation.

Use the outline-[<value>] syntax to set the outline width based on a completely custom value:

<div class="outline-[2vw] ...">  <!-- ... --></div>

For CSS variables, you can also use the outline-(length:<custom-property>) syntax:

<div class="outline-(length:--my-outline-width) ...">  <!-- ... --></div>

This is just a shorthand for outline-[length:var(<custom-property>)] that adds the var() function for you automatically.

Prefix an outline-width utility with a breakpoint variant like md: to only apply the utility at medium screen sizes and above:

<div class="outline md:outline-2 ...">  <!-- ... --></div>
