🙋 Introduction

The border-block-style property in CSS is a shorthand property that allows you to define the style of the block-start and block-end borders of an element. In a writing mode, "block" refers to the top and bottom borders in a horizontal writing mode (such as English) or the right and left borders in a vertical writing mode (such as Japanese).

This property is useful for setting the style of borders along the block axis, providing more control and flexibility in your design.

💡 Syntax

The border-block-style property can be used with one or two values. If one value is specified, it applies to both the block-start and block-end borders. If two values are specified, the first applies to the block-start border, and the second applies to the block-end border.

Syntax

Copied

element {
  border-block-style: style;
}

style: Specifies the line style of the border. This can be any valid border style value like solid, dashed, dotted, double, groove, ridge, inset, outset, none, or hidden.

🎛️ Default Value

The default value for border-block-style is none, which means that no border is drawn unless a specific style is defined.
