🙋 Introduction

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

This property is particularly useful when you want to create a border on only the top side of an element, allowing for more control over the appearance of your content.

💡 Syntax

The border-top property can be used with one, two, or three values depending on what you want to specify. The values correspond to the border's width, style, and color.

Syntax

Copied

element {
  border-top: width style color;
}

width: Specifies the thickness of the border (e.g., 1px, 0.5em, thin, medium, thick).
style: Specifies the line style of the border (e.g., solid, dashed, dotted, double, none).
color: Specifies the color of the border (e.g., red, #000, rgb(0, 0, 0)).

🎛️ Default Value

The default value for the border-top property is medium none color, where:

medium is the default width,
none means no border is shown, and
color defaults to the current text color of the element.
