Styling Your Factor App

Styling your Factor applications is simple and standard. Factor uses native conventions allowed in Vite which means anything that works there will work in Factor.

Custom CSS

Including custom CSS works as normal in Vite. This means you can include .css files or any preprocessor files natively from your components.

Factor natively supports the Less preprocessor so you should be able to work with .less files and syntax natively. Note that we recommend only using the nesting functionality of pre-processors while using standard CSS for everything else.

In the near future, CSS nesting will become native, and therefore we won't need pre-processors at all.


Factor natively supports TailwindCSS and we recommend you use it although it's not required.

To set up Tailwind, just add a tailwind.config.ts to the root of your application and configure it according to their documentation.

Factor Tailwind Colors and Config

If you are using Factor UI or UI from Factor plugins, we recommend you configure at least two custom Tailwind color schemes: color and primary.

  • "color" scheme: The contrast color scheme associated with text and borders. Allowing standard classes for these common elements: text-slate-500 or border-slate-200.
  • "primary" scheme Typically applications pick a primary color (purple in Factor's case) and use this often. Setting this scheme allows UI libraries to stylize according to your brand.

Here is how tailwind.config.ts might look:

// tailwind.config.ts
module.exports = {
  // ...other config...
  theme: {
    colors: {
      transparent: "transparent",
      primary: {
        50: "#f6f5ff",
        100: "#eeebff",
        200: "#d4ccff",
        300: "#baadff",
        400: "#8670ff",
        500: "#5233ff",
        600: "#4a2ee6",
        700: "#3e26bf",
        800: "#311f99",
        900: "#220082",

      color: {
        25: "#fafafa",
        50: "#F8FAFC",
        75: "#F8FAFC",
        100: "#e3eaf3",
        200: "#E3E8EE",
        300: "#d1dce5",
        400: "#aec2d2",
        500: "#8ba8bf",
        600: "#7d97ac",
        700: "#687e8f",
        800: "#536573",
        900: "#44525e",
