Tailwind 1.3 added the ability to specify a line-height for each font-size in your config file.

The following example sets the base font-size to 1rem, and the line-height to 1.5.

// tailwind.config.js

module.exports = {
  theme: {
    fontSize: {
      base: ['1rem', '1.5'],
    },
  },
}

Say goodbye to fiddling with leading-* classes in your markup.
