Just another mask! 
A very lightweight extension for the core/group gutenberg block. 
This adds an option, under the group blocks style tab, to add different top or bottom masks to a group block. 
You will love it. 🙂

You can use this plugin to prevent your site from appearing in the server logs of referred pages as a referrer. The operators of the referred pages cannot see where their visitors come from any more.
For example, this plugin will automatically convert all external links to this format
https://href.li/?http://example.com/
This is an anonymous link to example.com which prevents the original site from appearing as a referrer in the log files of the referred page.
Plugin based on the WP Blank Referer by blackhatzen.

Anonymize Links

Anonymize all your external links with the href.li service.
