Overview

An <sp-link> allows users to navigate to a different location. They can be presented in-line inside a paragraph or as a standalone text.

Usage

yarn add @spectrum-web-components/link

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

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

When looking to leverage the Link base class as a type and/or for extension purposes, do so via:

import { Link } from '@spectrum-web-components/link';

Variants

This is a <sp-link href="#">primary link</sp-link>.

This is a <sp-link href="#" variant="secondary">secondary link</sp-link>.

<p>This is a <sp-link quiet href="#">quiet primary link</sp-link>.</p>
<p>This is a <sp-link quiet variant="secondary" href="#">quiet secondary link</sp-link>.</p>
<div
    style="background-color: var(--spectrum-docs-static-white-background-color); padding: 15px 20px; display: inline-block;"
>
    <p style="color: var(--spectrum-white);">
        This is a
        <sp-link static-color="white" quiet href="#">quiet link</sp-link>
        over a background.
    </p>
</div>

Static colored links

When a link needs to be placed on top of a colored background or a visual it may be appropriate to ship it with a static color, regardless of the theme settings with which it is delivered. Leverage the static-color attribute with its white or black values to ensure the delivery is the same in all contexts.

<div
    style="background-color: var(--spectrum-docs-static-white-background-color); padding: 15px 20px; display: inline-block;"
>
    <p style="color: var(--spectrum-white);">
        This
        <sp-link static-color="white" href="#">link</sp-link>
        is over a background.
    </p>
</div>

<div
    style="background-color: var(--spectrum-docs-static-black-background-color); padding: 15px 20px; display: inline-block;"
>
    <p style="color: var(--spectrum-black);">
        This
        <sp-link static-color="black" href="#">link</sp-link>
        is over a background.
    </p>
</div>

States

Disabled links

Disabled links are blue, unfocusable, unclickable and should not propagate any events.

This is a <sp-link disabled href="#">disabled link</sp-link>.

Download attribute

The download attribute on an <a> tag prompts a user to download a link as opposed to navigating to it. This attribute has been carried forward to <sp-link> to function the same.

While it functions this way without assigning a value, actually assigning the value allows custom naming of the download link in accordance with standard <a> rules defined by the browser.

This is a <sp-link download="myfile.txt" href="#">download link</sp-link>.

Accessibility

Best Practices

• Use links in body copy and not in titles. For a larger call to action, consider using a button instead.
• Identify the target of each link directly in the link text to communicate context and set clear expectations about where the link will go.
• Be mindful of link placement and language, and create experiences that are inclusive of users navigating with screen readers, who may navigate links without their surrounding language.
• It’s more accessible and inclusive to write link text as unique descriptions of the navigational target or function.
• Implement skip links to improve navigation for keyboard and screen reader users when necessary, especially when the page has many sections and lengthy scroll.
• For links that open in a new tab, add target="_blank", rel="noopener noreferrer" and a UI icon to the link.
• Add aria-label or aria-labelledby to links for screen readers who need additional context. Links can be more concise to lessen visible noise, but adding these attributes can help make the purpose of the link more clear.
• Ensure strong color contrast between the link and its background. For users with low vision,consider using 7:1 ratio for critical links and 21:1 ratio for severe vision impairments.

Keyboard Interaction

• Tab: Move focus to the next focusable element.
• Enter: Activate the link.
• Shift + F10 (Optional): Open the context menu for the link.
