{{ $usage := `lazyimg:

Usage like:
|
|
- {{ partial "lazyimg" "image.jpg" }}
|
|
- {{ partial "lazyimg" (resources.Get "image.jpg") }}
|
|
|
|
...or more verbose by specifying a dict overriding the site.Params.lazyimg, e.g.:
|
|
- {{ partial "lazyimg" (dict "resizer" "auto" "renderer" "lqip") }}
|
|
- {{ partial "lazyimg" (dict "img" "image.jpg" "responsiveSizes" (slice "320px" "640px") "resizer" "responsive") }}
|
|
|
|
Please ensure that image exists in ./assets directory.
