+ Importing components depends on how your application works. If you intend
+ to use the Tailwind Elements ES
format, you must first import
+ the component and then initialize it with the initTE
method.
+ If you are going to use the UMD
format, just import the
+ tw-elements
package.
+
+ Using the Lightbox component doesn't require any additional JavaScript
+ code - simply add a div
wrapper with a
+ data-te-lightbox-init
attribute and use other data attributes
+ to set all options. For ES
format, you must first import and
+ call the initTE
method.
+
+ Options can be passed via data attributes or JavaScript. For data
+ attributes, append the option name to data-te-
, as in
+ data-te-caption=""
.

+
+ To ensure the proper performance of the page, it is recommended to include
+ thumbnails of images in the src attribute. Then in the
+ data-te-img
+ attribute add the path to the image with higher resolution. If the
+ data-te-img
attribute is omitted, the lightbox will display the
+ same image as in the reduced size.
+
+ You can improve the look of the images by adding + shadows + and rounded corners. +
+ + + {{< twsnippet/demo id="example3" >}} ++ Loaded images can have any aspect ratio. Their size will be automatically + adjusted to the window when you open the lightbox. +
+ + + {{< twsnippet/demo id="example4" >}} +
+ The data-te-zoom-level
attribute allows you to define the size
+ of a single zoom in / zoom out.
+
+ By adding a data-te-lightbox-disabled
attribute to any image,
+ you can exclude it from your lightbox. In the example below, the third image
+ has been disabled.
+
+ Image captions can be added using the
+ data-te-caption
attribute. If it is not set, the data is taken
+ from the alt
attribute. When you want to disable caption, leave
+ the data-te-caption
empty.
+
+ The lightbox can be successfully operated via JavaScript. There are many
+ public methods available such as open
, slide
,
+ zoomIn
, zoomOut
, or close
. All are
+ described in the API tab.
+
+ If you are looking for more advanced options, try + Bootstrap Lightbox + from MDBootstrap. +
