Enhance visual clarity with CSS Outline! Explore examples for precise styling, mastering the art of defining and highlighting elements in your web projects effortlessly.

An outline is a line drawn outside the element's border.

CSS Outline

An outline is a line that is drawn around elements, OUTSIDE the borders, to make the element "stand out".

CSS has the following outline properties:

  • outline-style
  • outline-color
  • outline-width
  • outline-offset
  • outline

Note: Outline differs from borders! Unlike border, the outline is drawn outside the element's border, and may overlap other content. Also, the outline is NOT a part of the element's dimensions; the element's total width and height is not affected by the width of the outline.

CSS Outline Style

The outline-style property specifies the style of the outline, and can have one of the following values:

  • dotted - Defines a dotted outline
  • dashed - Defines a dashed outline
  • solid - Defines a solid outline
  • double - Defines a double outline
  • groove - Defines a 3D grooved outline
  • ridge - Defines a 3D ridged outline
  • inset - Defines a 3D inset outline
  • outset - Defines a 3D outset outline
  • none - Defines no outline
  • hidden - Defines a hidden outline

The following example shows the different outline-style values:


Demonstration of the different outline styles:

p.dotted {outline-style: dotted;}
p.dashed {outline-style: dashed;}
p.solid {outline-style: solid;}
p.double {outline-style: double;}
p.groove {outline-style: groove;}
p.ridge {outline-style: ridge;}
p.inset {outline-style: inset;}
p.outset {outline-style: outset;}


Note: None of the other outline properties (which you will learn more about in the next chapters) will have ANY effect unless the outline-style property is set!
