To create links relative to the language being used add a // at the start of the link. This will transform your link into a pseudo-absolute link

Assuming the site url is localhost and we are editing a src file located at `content/en/docs/about/

This only applies to <a> tags

[Relative](new-link) => will be converted to localhost/en/docs/about/test/new-link
[Absolute](/new-link) => will be converted to localhost/new-link
[Pseudo Absolute](//new-link) => will be converted to localhost/en/new-link
[Explicit Absolute](http://localhost/en/new-link) => will be kept intact.
