Tailwind CSS best practices

Utility classes

1. When writing a string of multiple utility classes, always do so in an order with meaning. The "Concentric CSS" approach works well with utility classes (i.e,. 1. positioning/visibility 2. box model 3. borders 4. backgrounds 5. typography 6. other visual adjustments). Once you establish a familiar pattern of ordering, parsing through long strings of utility classes will become much, much faster so a little more effort up front goes a long way!

2. Always use fewer utility classes when possible. For example, use mx-2 instead of ml-2 mr-2 and don't be afraid to use the simpler p-4 lg:pt-8 instead of the longer, more complicated pt-4 lg:pt-8 pr-4 pb-4 pl-4.

3. Prefix all utility classes that will only apply at a certain breakpoint with that breakpoint's prefix. For example, use block lg:flex lg:flex-col lg:justify-center instead of block lg:flex flex-col justify-center to make it very clear that the flexbox utilities are only applicable at the

# Proof of concept - import maps with JSX transpilation.  Can trivially
# be extended to TypeScript and all the languages currently supported

#  * Have `find_javascript_files_in_tree` in importmap-rails to not only
#      find JS files, but also files that can be transpiled to JS.  
#  * Add sprockets JSX transformer, making use of esbuild
