Implementation

Open Vimeo Lightbox

Add [data-vimeo-lightbox-control="open"] to any element. When the user clicks this element that will open the lightbox.
To load the correct Vimeo video, locate the numeric ID in the Vimeo URL (e.g., 1019191082). Ensure the video is allowed to be embedded under its Vimeo settings. Add this ID to the attribute [data-vimeo-lightbox-id=“1019191082”].
To show a placeholder image when loading the Vimeo video add a <img> element with the attr [data-vimeo-lightbox-placeholder] attached as a child of the [data-vimeo-lightbox-control="open"]. This image can be hidden with display: none; and will only be used as data.

<button data-vimeo-lightbox-control="open" data-vimeo-lightbox-id="1019191082">
  <img data-vimeo-lightbox-placeholder="" src="image.jpg" alt="">
  <span>Open Video</span>
</button>

Close Vimeo Lightbox

Add [data-vimeo-lightbox-control="close"] to any element. When the user clicks this element it will close the lightbox and pause the video. Clicking the esc button on your keyboard will also close the lightbox.

<button data-vimeo-lightbox-control="close">Close Video</button>

Update Size (Aspect Ratio)

When the attribute [data-vimeo-update-size=“true”] is set to true, the player will retrieve the video’s dimensions and update the .vimeo-lightbox__before element’s padding-top to maintain the correct aspect ratio in percentages. Example: padding-top: 56.25%; = 16:9 ratio.

When the attribute [data-vimeo-update-size="cover"] is set the video player will cover the parent element. Make sure to put position: relative; on the parent.

Muted

Set the attribute [data-vimeo-muted=“true”] to start the video muted. The user can toggle the mute state by clicking an element with the attribute [data-vimeo-control=“mute”].

More information

Activated

When the lightbox is active it will set the [data-vimeo-activated="loading"], this will already show the dark background via CSS. When the information of the video is fetched it will change to [data-vimeo-activated="true"] and show the video player via CSS.

Play/Pause

The elements with the attributes [data-vimeo-control=“play”] and [data-vimeo-control=“pause”] allow the user to play or pause the video. These actions update the [data-vimeo-playing="false"] attribute from “false” to “true” or vice versa. You can use this attribute to control the visibility of the player interface during playback.

Fullscreen

The user can enter fullscreen mode by clicking an element with the attribute [data-vimeo-control=“fullscreen”]. If fullscreen is not supported on a device or browser (e.g., some mobile devices), the fullscreen button will not be displayed.

Loading

While the video is loading, the element with the class .vimeo-lightbox__loading is visible. Once the video finishes loading, the attribute [data-vimeo-loaded=“true”] is set to true, allowing you to hide the loading indicator.

Placeholder

Before the video loads, a placeholder image with the class .vimeo-lightbox__placeholder is displayed. When the attribute [data-vimeo-loaded=“true”] is true, the placeholder is hidden.

Duration

On load, the attribute [data-vimeo-duration] displays the total duration of the video. Once the video starts playing, it updates to show the current elapsed time.

Timeline

The timeline consists of an <input type="range"> element and a <progress> element. These components allow the user to control the video timeline. Dragging or clicking the timeline enables the user to skip to a specific point in the video.

Hover Player

When the user hovers over the video while it is playing but does not move the mouse for three seconds, the attribute [data-vimeo-hover=“false”] is set. This can be used to automatically hide the interface even if the mouse remains over the video player.
