Installation

Red Hat CDN

CDN Prerelease

We are currently working on our CDN, which will be soon moving into beta. This will be the preferred method of installation in the near future. If you are a Red Hat associate and have questions or comments about the CDN or installation process please join us in our Red Hat Design System Google chat.

In the meantime, install this component using npm

The recommended way to load RHDS is via the Red Hat Digital Experience CDN, and using an import map.

If you have full control over the page you are using, add an import map to the <head>, pointing to the CDN, or update any existing import map. If you are not responsible for the page's <head>, request that the page owner makes the change on your behalf.

<script type="importmap">
  {
    "imports": {
      "@rhds/elements/": "https://www.redhatstatic.com/dx/v1-alpha/@rhds/elements@1.1.0/elements/",
      "@patternfly/elements/": "https://www.redhatstatic.com/dx/v1-alpha/@patternfly/elements@2.2.2/"
    }
  }
</script>

Once the import map is established, you can load the element with the following module, containing a bare module specifier:

<script type="module">
  import '@rhds/elements/rh-cta/rh-cta.js';
</script>

Note that Modules may be placed in the <head>: since they are deferred by default, they will not block rendering.

Lightdom CSS

Lightdom CSS is required for this element to ensure a reduced Cumulative Layout Shift (CLS) experience before the element has fully initialized.

<link rel="stylesheet" href="https://www.redhatstatic.com/dx/v1-alpha/@rhds/elements@1.1.0/rh-cta/rh-cta-lightdom.css">
 NPM

Install RHDS using your team's preferred NPM package manager, e.g.

npm install @rhds/elements

Once that's been accomplished, you will need to use a bundler to resolve the bare module specifiers and optionally optimize the package for your site's particular use case and needs. Comprehensive guides to bundling are beyond the scope of this page; read more about bundlers on their websites:

Lightdom CSS

Lightdom CSS is required for this element to ensure a reduced Cumulative Layout Shift (CLS) experience before the element has fully initialized.

<link rel="stylesheet" href="/path/to/@rhds/elements/elements/rh-cta/rh-cta-lightdom.css">

Replace /path/to in the href attribute with the installation path to the rh-cta directory in your project.

 JSPM

Public CDNs

JSPM and other public CDNs should not be used on corporate domains. Use them for development purposes only!

Add an import map to the <head>, pointing to the CDN, or update any existing import map.

<script type="importmap">
  {
    "imports": {
      "@rhds/elements/": "https://jspm.dev/@rhds/elements/",
      "@patternfly/elements/": "https://jspm.dev/@patternfly/elements/"
    }
  }
</script>

Once the import map is established, you can load the element with the following module, containing a bare module specifier:

<script type="module">
  import '@rhds/elements/rh-cta/rh-cta.js';
</script>

Note that Modules may be placed in the <head>: since they are deferred by default, they will not block rendering.

Usage 

<rh-cta href="#default">Default</rh-cta>

rh-cta

Slots 1
Slot Name Description
undefined

The default slot contains the link text when the href attribute is set. In case there is no href attribute, an anchor tag (<a href="...">) should be the first child inside rh-cta element. Less preferred but allowed for specific use-cases include: <button> (note however that the button tag is not supported for the default CTA styles).
Attributes 8
DOM Property Description Type Default
variant

Indicates the importance of this call-to-action in the context of the page. Will also influence how the call-to-action is styled.

  • Primary: Use for the primary or most important link. This variant is the highest in hierarchy and can also be used to play a video in a Modal or large container.
  • Secondary: Use for secondary or general links. This variant is lower in hierarchy than the Primary variant and can be used multiple times in the same container or layout.
  • Brick: Use to group links together. Only the Brick variant can stretch to fit a container or grid, otherwise the text label padding in other variants stays the same.
  • Default (no variant): Use for tertiary or the least important links. This variant is the lowest in hierarchy and can be used multiple times in the same container or layout.
