Add tailwindcss to your ABP MVC UI

Table of Contents


In this post we will explore how to add TailWind CSS to your ABP MVC application. We will configure tailwind and create a new landing page with tailwind. Tailwind comes with the JIT mode. so you will only use the css need not the whole library. This will result in smaller css file compared to another framework.


Make sure to install node, npm, .net6 and abp

Create an abp App and Run Migrations

Create the App

Run the following command to create the abp app.

abp new AbpTailwindMvc

Run Migrations

change directory to src/AbpTailwindMvc.DbMigrator and run the migration project

dotnet run

This will create the migrations and seed the data for your project.

Install Tailwind

Navigate to src/AbpTailwindMvc.Web project and then init npm.

Install npm packages

Lets add the required packages for the tailwind css.

npm install -D tailwindcss postcss autoprefixer

Initialize Tailwind

To initialize tailwind run the following command.

npx tailwindcss init --postcss

This will create tailwind config file tailwind.config.js and postcss config file postcss.config.js

Update the tailwind config

module.exports = {
  content: ['!**/{bin,obj,node_modules}/**', '**/*.{cshtml,html}'],
  theme: {
    extend: {},
  corePlugins: {
    preflight: false,
  //prefix: 'tw-',
  plugins: [],

We have make 2 changes in the default config.

  • We have updated the content to look for cshtml and html files
  • We have remove the preflight

Create Tailwind css files

We need to create 2 css files

  • /Style/tailwind.css // This is the input
  • /wwwroot/tailwind.css // This is the output

Update the input file with the imports

@import 'tailwindcss/components';
@import 'tailwindcss/utilities';

Update the package.json

We will update the scripts section of the package.json

"scripts": {
"test": "echo \"Error: no test specified\" && exit 1",
"buildcss:dev": "npx tailwindcss --config tailwind.config.js --postcss postcss.config.js -i ./Style/tailwind.css -o ./wwwroot/tailwind.css",
"buildcss:release": "npx tailwindcss --config tailwind.config.js --postcss postcss.config.js -i ./Style/tailwind.css -o ./wwwroot/tailwind.css --minify",
"watch": "npx tailwindcss --config tailwind.config.js --postcss postcss.config.js -i ./Style/tailwind.css -o ./wwwroot/tailwind.css --watch"

We have add the 3 new scripts to the our package.json

  • buildcss:dev this will build the css based on the tailwind config
  • buildcss:release this will build minified css based on the tailwind config
  • watch will watch for the new changes and create update the output file

Add tailwindcss to you MVC app bundle

In the AbpTailwindMvcWebModule update the ConfigureBundles method

Configure<AbpBundlingOptions>(options =>
                    bundle =>

Update csproj

We need to build the css before the project is launched. To do that we will update the csproj and create a build task.

<Target Name="BuildCSS" BeforeTargets="Compile">
    <Exec Command="npm run buildcss:dev" Condition=" '$(Configuration)' == 'Debug' " />
    <Exec Command="npm run buildcss:release" Condition=" '$(Configuration)' == 'Release' " />

This command will run the npm command before the build so that we will have our css complied and ready to be displayed.


To apply a background color use bg-gray-200 you will see the color change.
