We removes the less compiler in j4 for 2 reasons.

Joomla switched to scss and the less compiler was out of date.

So you have to compile your less on your local machine and upload the CSS file.

There is some good documentation on Joomla 4 and the use of SCSS. https://docs.joomla.org/J4.x:SCSS_and_Sass/en

You can compile all Joomlaǃ core css files with the command npm run build:css or if someone needs to build a specific folder: npm run build:css -- templates/cassiopeia/scss or if they want to watch a folder: npm run watch -- templates/cassiopeia/scss
