Tailwind Config

How to configure your tailwind.config file

The tailwind.config.js file is used in Tailwind CSS to configure and customize various aspects of the framework. It serves as the central configuration file for your Tailwind CSS project.

Here are some common use cases for the tailwind.config.js file:

  • Customizing colors: You can define or override the default color palette used in your project by modifying the theme section in the configuration file. This allows you to specify your own colors or modify existing color values.

  • Adding or extending utility classes: Tailwind CSS provides a vast set of utility classes out of the box. However, you can further extend or customize these classes by using the variants and plugins sections in the configuration file. This allows you to add new utility classes or modify existing ones to fit your project's needs.

  • Enabling or disabling features: Tailwind CSS offers various features and modules that you can enable or disable based on your requirements. The configuration file allows you to control which features are included in your project, such as typography, spacing, gradients, etc.

  • Defining breakpoints: Tailwind CSS utilizes responsive design principles, and you can define your own breakpoints for different screen sizes. The configuration file allows you to specify breakpoints and customize the responsive behavior of utility classes like margin, padding, and display.

The tailwind.config.js file provides flexibility and control over various aspects of the Tailwind CSS framework, allowing you to tailor it to your specific project requirements.

In Vactory 4, You tailwind config file might look like this

tailwind.config.js

const content = ["./pages/**/*.{js,ts,jsx,tsx}", "./components/**/*.{js,ts,jsx,tsx}"]


module.exports = {
    mode: "jit",
    content: content,
    corePlugins: {
        preflight: false,
    },
    theme: {
        container: {
            center: true,
        },
        extend: {
            fontFamily: {
                rtl: process.env.POSTCSS_CONFIG
                    ? ["Cairo"]
                    : ["Cairo", ...defaultTheme.fontFamily.sans],
            },
            colors: {
                primary: {
                    DEFAULT: "#1552EF",
                    25: "#F5F8FE",
                    50: "#E7EDFD",
                },
            },
            screens: {
                xs: "576px",
                sm: "640px",
            },
        },
    },
    plugins: [],
}

Let's break down the important elements of the file:

  • mode: "jit": To Enabling JIT mode which (stands for Just-In-Time) that generates your styles on-demand as you author your templates instead of generating everything in advance at initial build time.

  • content: The content section of your tailwind.config.js file is where you configure the paths to all of your HTML templates, JavaScript components, and any other source files that contain Tailwind class names.

  • preflight: refers to CSS reset and normalize styles, which aim to ensure consistent rendering across different browsers by removing any inherent styling and inconsistencies. They also include some sensible default styles for typography, headings, lists, etc. In our Vactory project, we are disabling preflight and importing a customized file which we called it preflight.css

  • theme: The theme section of your tailwind.config.js file is where you define your project’s color palette, type scale, fonts, breakpoints, border radius values, and more. Check more about this section here: https://tailwindcss.com/docs/theme

  • plugins: Plugins let you register new styles for Tailwind to inject into the user’s stylesheet using JavaScript instead of CSS. Read more about plugins here: https://tailwindcss.com/docs/plugins
