What stands out

A quick read of the recorded project description.

01

Provides both a Stylus .user.css and a Tampermonkey .user.js installation artifact

02

npm-based build scripts: build, watch, and release commands

03

Supports Stylus Live Reload, automatically refreshing styles after files are saved

04

The README self-describes as an ALPHA version, with content mostly taken from a theme the author is working on, and does not promise completeness

05

Uses the MIT license, permitting use, modification, commercial use, and distribution

Template Details

This is a starter template for a user style theme, intended to help developers write CSS that overrides a website's appearance and package it into .user.css or .user.js files that browser extensions can install. The repository provides two installation methods: Stylus users can install release/theme.user.css directly, and Tampermonkey users can install release/theme.user.js.

The template includes a Node.js-based build workflow. After cloning the repository, run npm install to install dependencies, npm run build to build the theme, npm run watch to continuously watch for changes and rebuild automatically, and npm run release to generate the final release version. During development, using Stylus's Live Reload feature is recommended; check Check for updates and Live reload in the installation window. On Chrome, you must also enable Allow access to file URLs on the extension details page for Live Reload to work.

The README explicitly marks this as an ALPHA version, and most of the content is taken directly from a theme the author is developing. The author states that the current state may be useful but provides no guarantees. It is therefore better suited as a starting point reference than as a complete finished product. The materials do not specify which websites are supported, which style rules are included, or the size and compatibility scope of the build output.

Is it right for your project?

Use Cases

  • Writing custom appearance styles for a website and packaging them into a user style file
  • Using existing theme code as a starting point and adapting it into your own website theme
  • Repeatedly debugging CSS override effects locally with watch and Live Reload
  • Needing to distribute the same theme to both Stylus and Tampermonkey users

Suitable For

  • Developers familiar with CSS who want to override website styles using browser extensions
  • User style authors using Stylus or Tampermonkey
  • Anyone who needs a cloneable, buildable user style project skeleton

Getting started & customization

Use these recorded setup notes alongside the repository instructions for your chosen version.

  1. 1

    Before use, install the Stylus or Tampermonkey extension in your browser; Stylish is no longer supported or recommended

  2. 2

    Modifying the theme requires git and Node.js locally; after cloning the repository, run npm install to install dependencies

  3. 3

    The build command is npm run build, continuous watching uses npm run watch, and release versions use npm run release

  4. 4

    During development, you can check Check for updates and Live reload in the Stylus installation window; on Chrome, enable Allow access to file URLs on the extension details page

  5. 5

    Third-party assets such as demo images must be checked separately under their respective licenses; the MIT license covers only the code

License & source material

Usage conditions & limitations

Free to use · keep license notice

This entry covers the free version under the MIT license in the public repository; the free scope is the code of this version and does not mean external services or third-party assets are free.

Must comply with when using

  • Free use, modification, commercial use, and distribution of this version's code are permitted.
  • When distributing copies or substantial portions of the code, retain the original author's copyright notice and the full MIT license notice.
  • The code is provided as is; warranties and limitations of liability are governed by the original license and applicable law.

Additional costs & items to verify

  • The README explicitly marks this as an ALPHA version, and the author states that most of the content is taken directly from a theme they are developing; the current state may be useful but comes with no guarantees, so it is not suitable as a complete finished product for direct production use.
  • The project does not support and does not recommend the Stylish extension; using this theme requires switching to browser extensions such as Stylus or Tampermonkey.
  • When using Stylus's Live Reload feature in Chrome, you must manually enable the Allow access to file URLs permission on the extension details page, otherwise automatic refresh will not work.
  • Demo images, fonts, icons, and other third-party assets must be checked under their respective licenses and cannot be judged solely by the code's MIT license.
  • External services such as domains, hosting, databases, payments, or AI may incur separate charges.

How this score is calculated

Our heuristic uses license records (up to 30), a demo link (12), a preview (10), stars (15), recorded maintenance (15), description completeness (8), feature records (5) and classification data (5). It is not a code, security or performance test, or a Google score. A link does not establish tested functionality.

## Using the Theme

### Install A Browser Plugin

There are a couple of options for installing the theme in your browser.

[![Stylus](https://github.com/openstyles/stylus/raw/master/images/icon/32.png) Stylus](https://add0n.com/stylus.html) is a browser extension for Chrome, Firefox, and Opera that allows you to override the styling of websites, to change their appearance.

  * [Stylus for Chrome](https://chrome.google.com/webstore/detail/clngdbkpkpeebahjckkjfobafhncgmne)
  * [Stylus for Firefox](https://addons.mozilla.org/firefox/addon/styl-us/)
  * [Stylus for Opera](https://addons.opera.com/extensions/details/stylus/)


[![Tampermonkey](https://github.com/Tampermonkey/tampermonkey/raw/master/images/icon.png) Tampermonkey](http://tampermonkey.net/) is a browser extension for Chrome, Firefox, Edge, Opera, and Safari that allows running scripts to change the behavior of websites and add new functionality.

  * [Tampermonkey for Chrome](https://chrome.google.com/webstore/detail/dhdgffkkebhmkfjojejmpbldmpobfkfo)
  * [Tampermonkey for Firefox](https://addons.mozilla.org/en-US/firefox/addon/tampermonkey/)
  * [Tampermonkey for Edge](https://www.microsoft.com/store/apps/9NBLGGH5162S)
  * [Tampermonkey for Opera](https://addons.opera.com/en/extensions/details/tampermonkey-beta/)
  * [Tampermonkey for Safari](https://safari.tampermonkey.net/tampermonkey.safariextz)

> **Note:**
> Stylish is no longer supported, nor endorsed. What used to be a well known and respected extension was sold and resold and ended up in the hands of an analytics company that captures and transmits your browsing history. Fortunately there are now better options. The Stylish extension and the UserStyles.org website are no longer needed for this theme.


### Install the Theme

Once you've installed one of the extensions above, you are ready to install the theme:

  * From its home page at [OpenUserCSS](https://openusercss.org/)

Or directly from here:

  * For Stylus users:<br>
[![Install with Stylus](https://img.shields.io/badge/Install%20with-Stylus-00adad.svg)](https://github.com/simsrw73/boilerplate-userstyle-theme/raw/master/release/theme.user.css)

  * For Tampermonkey users:<br>
[![Install with Tampermonkey](https://img.shields.io/badge/Install%20with-Tampermonkey-00485b.svg)](https://github.com/simsrw73/boilerplate-userstyle-theme/raw/master/release/theme.user.js)

## Modifying the Theme

### Install Build Tools

  - [git](https://git-scm.com/downloads)
  - [Node.js](https://nodejs.org/en/)

### Clone the Repository

```shell
git clone https://github.com/simsrw73/boilerplate-userstyle-theme.git my-theme
```

### Install Build Dependencies

```shell
cd my-theme
npm install
```

### Build your Theme

```shell
npm run build
```

Or, to continuously monitor changes and automatically rebuild:

```shell
npm run watch
```

### Test your Theme

Load the theme in to your browser with the Stylus extension by either: dragging the file **"theme.user.css"** to your browser or using the Open Dialog in the browser (Ctrl-o). When Stylus opens the install window, check the options ***Check for updates*** and ***Live reload***, and then click the **Install style** button.


### Release your Theme

Build the final relase version of the theme:

```shell
npm run release
```


### Import the Theme to the Browser Plugin

Stylus is the best option for development. It has a feature, Live Reload, that detects changes to the file on disk and reloads the changes.

See [Installation](https://github.com/openstyles/stylus/wiki/Usercss#installation) in Stylus documentation.

> **Note:***
> For Chrome, permissions need to be enabled for Live Reload to work. Go to the Extensions page and Click on "Details" for the Stylus extension. Scroll down and enable "Allow access to file URLs"
