Required Scripts

<script async custom-element="amp-story" src="https://cdn.ampproject.org/v0/amp-story-1.0.js"></script>

Usage

amp-story-page-outlink provide a UI for a one-tap outlink experience. The outlink can be opened by users through a "swipe up" gesture, or a tap on the call to action element. A UI button prompting the viewer to open the attachment will appear at the bottom of every page with a amp-story-page-outlink element. It must have the layout="nodisplay" attribute.

amp-story-page-outlink requires a single a element child.


<amp-story-page id="page-outlink-example">
  <amp-story-grid-layer template="fill">
    <amp-img src="https://example.ampproject.org/helloworld/bg1.jpg" width="900" height="1600">
  </amp-story-grid-layer>
  <amp-story-page-outlink layout="nodisplay">
    <a href="https://www.google.com" title="Link Description"></a>
  </amp-story-page-outlink>
</amp-story-page>

Placement

The <amp-story-page-outlink> element must be the last child of <amp-story-page>, and must have the layout="nodisplay" attribute.

Both amp-story-page-outlink and amp-story-page-attachment must be the last child tag of an amp-story-page. Because of this, you may include neither or one, but not both.

Attributes

When no attributes are set, the default UI will render:

amp-story-page-outlink-default

<amp-story-page-outlink layout="nodisplay">
    <a href="https://www.google.com"></a>
</amp-story-page-outlink>

cta-text (optional)

String that customizes the button text. The default is "Swipe up".

amp-story-page-outlink-cta-text

<amp-story-page-outlink
  layout="nodisplay"
  cta-text="Read More">
  ...
</amp-story-page-outlink>

theme (optional)

String representing the color theme, default is light. Accepts values light, dark, and custom.

theme="custom" requires two additional attributes:

  • `cta-accent-color`: String that represents the custom theme’s color.
  • `cta-accent-element`: String that represents the element to apply the custom theme to. Accepts values `text` and `background`.

Contrast protection is automatically applied to ensure readability and a11y compliance. For example, when the accent element is "background", the higher contrast color (black or white) is applied to the text.
