Hello @nbeck415 I got tailwind to work with pug, but from a development standpoint, every time I make a change I must stop the container, run the script for postcss. Not sure how to make it so that it executes the script every time I save. I assume because the styles.css is being edited by postcss the container must always be rebuilt.

p.s. relies on the updated makefile

@nbeck415
This works

• The makefile build step is updated to run the postcss to generate the tailwind css styling in style.css

• Because the build step generates the style.css file, new tailwind styling will require to rerun make develop so the image containers the relevant updated styling.

  • Should add a note to readme about rerunning make develop
  • Docker Compose watch would be a good use here.

@nbeck415 Where you able to take a look at the makefile and see this would be the best place to add the custom npm tailwind css script?

If so, this PR is ready to be reviewed.
