Carousel Image

Use the lightning-carousel-image component to specify images for the lightning-carousel component. You can specify up to six images, which then appear in the order that you list them in the lightning-carousel component.

For each image, use the src attribute to specify the path to the image. Optionally use header and description attributes to provide a header and descriptive text that the carousel shows below the image. You can also hyperlink the images with the href attribute.

Use the alternative-text attribute to supply assistive text for each image.

1<lightning-carousel-image
2        src = "https://v1.lightningdesignsystem.com/assets/images/carousel/carousel-01.jpg"
3        header = "First Card"
4        description = "First card description."
5        alternative-text = "First card accessible description."
6        href = "https://www.example.com">
7    </lightning-carousel-image>

Use lightning-carousel-image within lightning-carousel, which implements the carousel blueprint in the Salesforce Lightning Design System (SLDS). The carousel adapts to SLDS 1 or SLDS 2 styling based on the org’s theme or the container app that you use.

To use images in your org, upload them as static resources in the Static Resources page in Setup. To reference a resource in lightning-carousel-image, use {property} syntax in your src attribute.

If the image path is invalid or the image doesn’t load because the user is offline or another reason, the description and alternative text replace the image.

This example uses static resources uploaded as a single image, and images uploaded in a zip file.

19                src={product2Url}
20                header="Fantastic product 2"
21                description="Fantastic product image in a zip file"
22                alternative-text="Fantastic product 2"
23            >
24            </lightning-carousel-image>
25        </lightning-carousel>

27</template>

The company logo was uploaded as a single image to a static resource named company_logo and imported as companyLogo. The Product1 and Product2 images were uploaded in a zip file to a static resource named company_products and imported as companyProducts.

1import { LightningElement } from "lwc";
2import companyLogo from "@salesforce/resourceUrl/company_logo";
3import companyProducts from "@salesforce/resourceUrl/company_products";

5export default class CarouselStaticResources extends LightningElement {
6  // Expose the static resource URL for use in the template
7  companyLogoUrl = companyLogo;
8
9  // Expose URL of assets included inside an archive file
10  product1Url = companyProducts + "/product1.png";
11  product2Url = companyProducts + "/product2.png";

lightning-carousel-image includes accessibility features provided by lightning-carousel. A carousel image appears with header text and a description. Use the alternative-text attribute to specify assistive text for each image.

lightning-carousel-image observes these roles, states, and properties.

• The indicator button (tab’s anchor) of a selected image has aria-selected="true", and all other tabs have aria-selected="false".
• The tab’s anchor of a selected image has tabindex="0", and all other tabs have tabindex="-1".
• Each image container (tab panel) contains an element with role="tabpanel".
• Each tab panel has an aria-labelledby attribute whose value is the ID of its associated indicator button.
• Each tab panel has an aria-hidden attribute whose value is toggled based on whether the panel is visible.
