🙋 Introduction

The border-left property in CSS is used to set the style, width, and color of the left border of an element.

This property allows you to control the appearance of the left edge of an element, enabling you to create visual separation or emphasis on specific parts of your content. The border-left property is a shorthand for setting border-left-width, border-left-style, and border-left-color in one declaration.

💡 Syntax

The syntax for the border-left property is as follows:

Syntax

Copied

element {
  border-left: width style color;
}

width: Specifies the thickness of the border (e.g., 2px, 0.1em, thin).
style: Specifies the style of the border (e.g., solid, dashed, dotted).
color: Specifies the color of the border (e.g., #000, red, rgba(0, 0, 0, 0.5)).

🎛️ Default Value

The default value of the border-left property is:

Syntax

Copied

element{
  border-left: medium none currentcolor;
}

This means that, by default, the left border is not displayed (none), with a medium thickness and using the current text color if it were to be applied.

🏠 Property Values

width: The thickness of the border. This can be a specific measurement (e.g., 2px), a relative size (e.g., thin, medium, thick), or a percentage.
style: The style of the border. Common values include:
- none: No border.
- solid: A solid line.
- dotted: A series of dots.
- dashed: A series of dashes.
- double: Two solid lines.
- groove: A 3D grooved border.
- ridge: A 3D ridged border.
- inset: A 3D inset border.
- outset: A 3D outset border.
color: The color of the border, which can be any valid CSS color value.
