PicoTargetBlank

A PicoCMS Plugin to Open External Links in a New Tab

Inspired by this.

Please consult PicoCMS' generic plugin installation instructions.

The plugin is enabled by default. You can disable it in config.yml:

PicoTargetBlank:
    enabled: false

You can also set the rel= attribute, or disable it with an empty string:

    rel: 'noopener noreferrer nofollow
or
    rel: ''

etc.

defaults to 'noopener noreferrer' if unspecified. See here for an explanation.

How it works

It picks the rendered page apart and compares each anchor's host to the server's value of $_SERVER['HTTP_HOST'] - if they differ, it adds target="_blank", the configurable rel attribute, a mouseover title and the external CSS class to the link.

CSS

CSS is not included with this plugin. If you want to add a small arrow to the link text, add this to your stylesheets:

a.external::after {
   line-height: 100%;
   vertical-align: super;
   font-size: 60%;
   content: "↗"
   }

There's no Unicode symbol for the commonly seen box with the outgoing arrow; you can use the above or do some SVG magic.

If you don't want the arrow on some external links, add the "noarrow" class. CSS:

a.external.noarrow::after { content: '' }
