Describe your use case and the problem you are facing

A lot of modern tooling (especially in Laravel space) have really pretty looking CLI outputs (mostly thanks to https://github.com/nunomaduro/termwind).

Using Termwind would be great, and could probably be used with WP-CLI, if it wasn't locked to PHP 8.

So the alternative is to have the output of the WP-CLI a bit more customizable. Increasing line height, making some other modifications to the output, etc.

Some styling is possible now, but that's not much.

Describe the solution you'd like

Currently, for instance, the WP_CLI::success method only has one parameter $message. Other commands such as error, line or log could have a second optional parameter $style where these parameters could be added as an array of items:

WP_CLI::success($message,
  [
    'color' => '#FEFEFE',
    'background' => 'green',
    'line-height' => '1.5',
    'style' => 'italic',
    'weight' => 'bold'
  ]
);

I think I'd much prefer adopting Termwind, vs. inventing our own version 😁

This might be a good candidate for a WP-CLI v3.0

So WP-CLI v3.0 would then be locked to PHP 8? 😅

Probably not going to happen but one can wish 😁
