jekyll-loading-lazy

This plugin adds loading="lazy" to all img and iframe tags on your Jekyll site. No configuration needed.
If a loading attribute is already present nothing is changed.

loading="lazy" causes images and iframes to load lazily without any JavaScript. Browser support is growing.
If a browser does not support the loading attribute, it will load the resource just like it would normally.

⭐ If you like it, star it or sponsor it. 💓

1. Add the following to your site's Gemfile:

   gem 'jekyll-loading-lazy'

2. add the following to your site's _config.yml:

   plugins:
     - jekyll-loading-lazy

   Note: if jekyll --version is less than 3.5 use:

   gems:
     - jekyll-loading-lazy

3. In your terminal, execute:

   bundle

4. (re)start your Jekyll server with:

   jekyll serve

Install the plugin as described above. That's basically all there is.

💡 Tip: Note that the github-pages gem runs in safe mode and only allows a defined set of plugins. To use this gem in GitHub Pages, you need to build your site locally or use a CI (e.g. Github Workflow) and deploy to your gh-pages branch. Click here for more information.

In case you want to prevent loading some images/iframes lazily, add loading="eager" to their tags. This might be useful to prevent flickering of images during navigation (e.g. the site's logo).

See the following examples to prevent lazy loading.

![an example](/image.jpg){:loading='eager'}

This example assumes you're using Kramdown (Jekyll is using it by default).

<img src="/image.jpg" alt="an example" loading="eager" />
