In this lesson, we learn how to generate custom utility classes in tailwind. We add new properties to our JavaScript config object to generate new helper classes to suit our needs.

Update gulpfile.js:

const gulp = require("gulp"); const postcss = require("gulp-postcss"); const tailwindcss = require("tailwindcss"); const PATHS = { css: "./src/styles.css", config: "./tailwind.js", dist: "./" }; gulp.task("css", () => { return gulp .src(PATHS.css) .pipe(postcss([tailwindcss(PATHS.config), require("autoprefixer")])) .pipe(gulp.dest(PATHS.dist)); }); gulp.task("default", ["css"], () => { gulp.watch(PATHS.config, ["css"]); });

For example, you want to add some custom margin and padding in tailwind.js file:

margin: { ‘auto‘: ‘auto‘, ‘px‘: ‘1px‘, ‘0‘: ‘0‘, ‘1‘: ‘0.25rem‘, ‘2‘: ‘0.5rem‘, ‘3‘: ‘0.75rem‘, ‘4‘: ‘1rem‘, ‘6‘: ‘1.5rem‘, ‘8‘: ‘2rem‘, ‘16‘: ‘4rem‘, //added ‘crazy‘: ‘8rem‘, //added }, padding: { ‘px‘: ‘1px‘, ‘0‘: ‘0‘, ‘1‘: ‘0.25rem‘, ‘2‘: ‘0.5rem‘, ‘3‘: ‘0.75rem‘, ‘4‘: ‘1rem‘, ‘6‘: ‘1.5rem‘, ‘8‘: ‘2rem‘, ‘16‘: ‘4rem‘, //added ‘crazy‘: ‘16rem‘, //added },

After run ‘gulp‘ command.
