🎨 CSS border-right-style: Styling the Right Edge with Precision

Borders can guide the eye, separate content, and add polish to layouts. The border-right-style property in CSS allows you to define the visual style of an element’s right border — helping you fine-tune your UI down to the edge.

🧾 What is border-right-style?

The border-right-style property defines the line pattern or appearance of the right border of an element. It can be solid, dotted, dashed, or even 3D-looking, depending on the effect you want to achieve.

🧬 Syntax

selector {
  border-right-style: none | solid | dotted | dashed | double | groove | ridge | inset | outset;
}

🔍 Available Style Values

Style	Description
none	No border on the right (invisible, takes up no space).
solid	A single straight solid line.
dotted	A dotted line made of circular dots.
dashed	A dashed line made of short line segments.
double	Two parallel solid lines (thicker than a regular line).
groove	Appears carved into the page (3D inset effect).
ridge	Appears raised from the page (3D outset effect).
inset	Makes the element look embedded (used mostly on input elements).
outset	Makes the element appear raised (opposite of inset).

🎯 Examples

1. A basic solid right border

.box {
  border-right-width: 3px;
  border-right-style: solid;
  border-right-color: #4CAF50;
}

Creates a clean, solid green line on the right side.

---

2. Dotted and dashed styles

.dotted-box {
  border-right: 2px dotted gray;
}

.dashed-box {
  border-right: 2px dashed orange;
}

Commonly used for less intrusive visual separation or decorative effects.

---

3. 3D-like styles

.card {
  border-right: 4px groove #888;
}

Adds a slightly inset, carved appearance to the border — best used for specific themes or vintage UIs.

🛠️ Tips for Effective Use

• Always pair with border-right-width to ensure visibility.
• Avoid overusing 3D effects like groove and ridge — they can look outdated in modern UIs.
• Combine with transitions and pseudo-classes (:hover, :focus) for interactive feedback.
• If you’re using the shorthand border-right, this style can be set directly inline with color and width.
