amp-inline-gallery
Description
Displays multiple similar pieces of content along a horizontal axis, with optional pagination dots and thumbnails.
Required Scripts
<script async custom-element="amp-inline-gallery" src="https://cdn.ampproject.org/v0/amp-inline-gallery-0.1.js"></script>
Supported Layouts
Usage
The <amp-inline-gallery>
component uses an <amp-base-carousel>
to display slides. The page must have the required scripts for both components in the document head. Typical usage might look like:
<amp-inline-gallery layout="container"> <amp-base-carousel class="gallery" layout="responsive" width="3.6" height="2" snap-align="center" loop visible-count="1.2" lightbox > <amp-img src="/static/inline-examples/images/image1.jpg" layout="responsive" width="450" height="300" ></amp-img> <amp-img src="/static/inline-examples/images/image2.jpg" layout="responsive" width="450" height="300" ></amp-img> <amp-img src="/static/inline-examples/images/image3.jpg" layout="responsive" width="450" height="300" ></amp-img> </amp-base-carousel> <amp-inline-gallery-pagination layout="nodisplay" inset> </amp-inline-gallery-pagination> </amp-inline-gallery>
The above example shows slides using an aspect ratio of 3:2, with 10% of a slide peeking on either side. An aspect ratio of 3.6:2 is used on the amp-base-carousel
to show 1.2 slides at a time.
Include pagination indicators
The <amp-inline-gallery-pagination>
component determines how a pagination idicator should be displayed. By default, no pagination indicator is displayed.
The pagination indicator renders as dots when there are eight or fewer slides in the amp-base-carousel
. For nine or more slides, the pagination indicator renders the current slide number and total number of slides, aligned to the right.
The pagination indicator location defaults to underneath the carousel. Adding the inset attribute to the <amp-inline-gallery-pagination>
tag will overlay the pagination indicator on the carousel. To use different styles for different screen sizes, use the media attribute:
<amp-inline-gallery layout="container"> <amp-base-carousel>…</amp-base-carousel> <amp-inline-gallery-pagination media="(max-width: 599px)" layout="nodisplay" inset > </amp-inline-gallery-pagination> <amp-inline-gallery-pagination media="(min-width: 600px)" layout="fixed-height" height="24" > </amp-inline-gallery-pagination> </amp-inline-gallery>
amp-inline-gallery-pagination
attributes
inset
(optional)
Displays the pagination indicator as inset, overlaying the carousel itself. When using inset
, you should give the <amp-inline-gallery-pagination>
element layout="nodisplay"
.
common attributes
The <amp-inline-gallery-pagination>
element includes common attributes extended to AMP components.
Include thumbnails
The amp-inline-gallery
component can display thumbnail preview in addition to, or instead of, the pagination indicators. By default, no thumbnails are shown in the gallery. Keep in mind the following best practices when using thumbnails:
- Avoid using both pagination indicators and thumbnails with less than eight slides. The indicator dots are redundant in smaller galleries.
- When using both pagination indicators and thumbnails, inset the pagination indicators to overlap the slides. View the code sample below to see an example.
- Use the
media
attribute to show pagination indicators on smaller mobile devices and thumbnails on larger screens. - Load lower resolution images at thumbnails by using
srcset
. You can omit thesizes
on<amp-img>
, it will be automatically generated based on the rendered width.
The example below demonstrates a gallery with thumbnails visible at larger resolutions.
<amp-inline-gallery layout="container"> <!-- The amp-layout with layout="container" is used to display the pagination on top of the carousel instead of the thumbnails. You can also use a div with `position: relative;` --> <amp-layout layout="container"> <amp-base-carousel class="gallery" layout="responsive" width="3" height="2" snap-align="center" loop > <amp-img class="slide" layout="flex-item" src="https://picsum.photos/id/779/600/400" srcset="https://picsum.photos/id/779/150/100 150w, https://picsum.photos/id/779/600/400 600w, https://picsum.photos/id/779/1200/800 1200w" > </amp-img> <amp-img class="slide" layout="flex-item" src="https://picsum.photos/id/1048/600/400" srcset="https://picsum.photos/id/1048/150/100 150w, https://picsum.photos/id/1048/600/400 600w, https://picsum.photos/id/1048/1200/800 1200w" > </amp-img> <amp-img class="slide" layout="flex-item" src="https://picsum.photos/id/108/600/400" srcset="https://picsum.photos/id/108/150/100 150w, https://picsum.photos/id/108/600/400 600w, https://picsum.photos/id/108/1200/800 1200w" > </amp-img> <amp-img class="slide" layout="flex-item" src="https://picsum.photos/id/130/600/400" srcset="https://picsum.photos/id/130/150/100 150w, https://picsum.photos/id/130/600/400 600w, https://picsum.photos/id/130/1200/800 1200w" > </amp-img> <amp-img class="slide" layout="flex-item" src="https://picsum.photos/id/14/600/400" srcset="https://picsum.photos/id/14/150/100 150w, https://picsum.photos/id/14/600/400 600w, https://picsum.photos/id/14/1200/800 1200w" > </amp-img> <amp-img class="slide" layout="flex-item" src="https://picsum.photos/id/165/600/400" srcset="https://picsum.photos/id/165/150/100 150w, https://picsum.photos/id/165/600/400 600w, https://picsum.photos/id/165/1200/800 1200w" > </amp-img> <amp-img class="slide" layout="flex-item" src="https://picsum.photos/id/179/600/400" srcset="https://picsum.photos/id/179/150/100 150w, https://picsum.photos/id/179/600/400 600w, https://picsum.photos/id/179/1200/800 1200w" > </amp-img> <amp-img class="slide" layout="flex-item" src="https://picsum.photos/id/392/600/400" srcset="https://picsum.photos/id/392/150/100 150w, https://picsum.photos/id/392/600/400 600w, https://picsum.photos/id/392/1200/800 1200w" > </amp-img> <amp-img class="slide" layout="flex-item" src="https://picsum.photos/id/468/600/400" srcset="https://picsum.photos/id/468/150/100 150w, https://picsum.photos/id/468/600/400 600w, https://picsum.photos/id/468/1200/800 1200w" > </amp-img> </amp-base-carousel> <!-- If using fewer than 8 slides, consider adding something like media="(max-width: 799px)". --> <amp-inline-gallery-pagination layout="nodisplay" inset> </amp-inline-gallery-pagination> </amp-layout> <amp-inline-gallery-thumbnails media="(min-width: 800px)" layout="fixed-height" height="96" > </amp-inline-gallery-thumbnails> </amp-inline-gallery>
