Unlock the Power of CSS Outlines
When it comes to adding visual flair to your website, CSS outlines are a game-changer. But what exactly are they, and how do they differ from borders?
The Difference Between Outlines and Borders
At first glance, outlines may seem similar to borders. However, there’s a key difference: outlines draw a line around the entire element, whereas borders can be customized to appear on specific sides. Additionally, outlines aren’t part of the box model, meaning the line is drawn outside of the element itself.

Mastering the Outline Shorthand Property
The outline shorthand property can be declared with one, two, or three values. For example:
outline: 1px solid #000;outline: dotted;outline: 2px dashed #f00;
Understanding Component Properties
The outline property is comprised of three individual properties: outline-color, outline-style, and outline-width. Let’s dive deeper into each:
outline-color
Sets the color of the textual and decorative parts of the outline. It can be specified via keywords, hex values, RGB/RGBA values, and HSL/HSLA values. Its default value is invert if the browser supports it; otherwise, its default value is currentColor.
outline-style
Specifies the type of line to be drawn. Its value can be any of the following keywords: auto, dotted, dashed, solid, double, groove, ridge, inset, outset, or none (no outline).
outline-width
Specifies the thickness of the line to be drawn. Its value can be any length value, or any of the following keywords: thin, medium, or thick.
