Overview

sp-divider brings clarity to a layout by grouping and dividing content that exists in close proximity. It can also be used to establish rhythm and hierarchy.

Usage

yarn add @spectrum-web-components/divider

Import the side effectful registration of <sp-divider> via:

import '@spectrum-web-components/divider/sp-divider.js';

import { Divider } from '@spectrum-web-components/divider';

Options

Horizontal dividers are used to separate content stacked vertically.

<h2 class="spectrum-Heading spectrum-Heading--sizeXS">Small</h2>
<sp-divider size="s"></sp-divider>
<p class="spectrum-Body">
  The small divider is used to divide similar components such as table rows,
  action button groups, and components within a panel.
</p>

<h2 class="spectrum-Heading spectrum-Heading--sizeS">Medium</h2>
<sp-divider size="m"></sp-divider>
<p class="spectrum-Body">
  The medium divider is used to divide subsections on a page, or to separate
  different groups of components such as panels, rails, etc.
</p>

<h2 class="spectrum-Heading spectrum-Heading--sizeM">Large</h2>
<sp-divider size="l"></sp-divider>
<p class="spectrum-Body">
  The large divider should be used only for page titles or section titles.
</p>

Vertical

Vertical dividers are used to separate content horizontally.

When a vertical divider is used inside of a flex container, use align-self: stretch; height: auto; on the divider.

<div style="height: 32px; display: flex;">
  <sp-action-button quiet label="Zoom in">
    <sp-icon-magnify slot="icon"></sp-icon-magnify>
  </sp-action-button>
  <sp-divider
    size="s"
    style="align-self: stretch; height: auto;"
    vertical
  ></sp-divider>
  <sp-action-button quiet label="Zoom in">
    <sp-icon-magnify slot="icon"></sp-icon-magnify>
  </sp-action-button>
</div>

<div style="height: 32px; display: flex;">
  <sp-action-button quiet label="Zoom in">
    <sp-icon-magnify slot="icon"></sp-icon-magnify>
  </sp-action-button>
  <sp-divider
    size="m"
    style="align-self: stretch; height: auto;"

  ></sp-divider>
  <sp-action-button quiet label="Zoom in">
    <sp-icon-magnify slot="icon"></sp-icon-magnify>
  </sp-action-button>
</div>

<div style="height: 32px; display: flex;">
  <sp-action-button quiet label="Zoom in">
    <sp-icon-magnify slot="icon"></sp-icon-magnify>
  </sp-action-button>
  <sp-divider
    size="l"
    style="align-self: stretch; height: auto;"
    vertical
  ></sp-divider>
  <sp-action-button quiet label="Zoom in">
    <sp-icon-magnify slot="icon"></sp-icon-magnify>
  </sp-action-button>
</div>

Static color

Use the static color option when a divider needs to be placed on top of a color background or visual. Static color dividers are available in black or white regardless of color theme.

<div
  style="background-color: var(--spectrum-docs-static-black-background-color); color: var(--spectrum-black); padding: 20px"
>
  <h2 class="spectrum-Heading spectrum-Heading--sizeS">
    Static black on light background
  </h2>
  <sp-divider static-color="black" size="m"></sp-divider>
  <p class="spectrum-Body">
    Use static black on light color or image backgrounds.
  </p>
</div>

<div
  style="background-color: var(--spectrum-docs-static-white-background-color); color: var(--spectrum-white); padding: 20px;"
>
  <h2 class="spectrum-Heading spectrum-Heading--sizeS">
    Static white on dark background
  </h2>
  <sp-divider static-color="white" size="m"></sp-divider>
  <p class="spectrum-Body">
    Use static white on dark color or image backgrounds.
  </p>
</div>

Accessibility

The <sp-divider> element implements the following accessibility features:

• ARIA role: Automatically sets role="separator" to ensure proper semantic meaning for assistive technologies
• Orientation support: When vertical is true, automatically sets aria-orientation="vertical" to indicate the divider's orientation

Best practices

• Medium or large dividers can be used with header text to visually create a section or page title. Place the divider below the header for best results.
• Ensure sufficient color contrast when using static-color variants on colored backgrounds.
• Use dividers to create meaningful visual separation, not just decorative lines.
• Use dividers sparingly; excessive use can diminish their visual impact.
