🙋 Introduction

The border-style property in CSS is used to define the style of the border around an element. It controls the appearance of the border, allowing you to choose from a variety of predefined styles, such as solid, dashed, dotted, and more.

This property is essential for adding visual structure and emphasis to elements on your web page.

💡 Syntax

The syntax for the border-style property allows you to specify one or more styles for the border sides.

Syntax

Copied

element {
  border-style: style;
}

You can define the style for all four sides of the border simultaneously, or specify them individually.

One value: Applies to all four sides (top, right, bottom, left).
Two values: The first value applies to the top and bottom, the second to the right and left.
Three values: The first value applies to the top, the second to the right and left, the third to the bottom.
Four values: Applies to the top, right, bottom, and left, respectively.

🎛️ Default Value

The default value of the border-style property is none, which means no border will be displayed.
