Unlock the Power of Stylelint: Take Your CSS to the Next Level

What is Stylelint?

Stylelint is a versatile tool that understands the latest CSS syntax and parses CSS-like syntaxes such as SCSS, Sass, and Less. It can extract embedded styles from HTML, Markdown, CSS-in-JS objects, and template literals, making it an essential tool for any developer.

Getting Started with Stylelint

To integrate Stylelint into your workflow, start by installing it along with the stylelint-config-standard, which enables a core set of rules based on common stylistic conventions. Create a configuration file in the root of your project, and you’re ready to run Stylelint on the command line.

npm install stylelint stylelint-config-standard

Create a .stylelintrc file in the root of your project with the following content:

{
  "extends": "stylelint-config-standard"
}

Beyond the Basics: Advanced Stylelint Features

While Stylelint is an excellent tool for catching errors, it can do so much more. With plugins like stylelint-order, you can automatically sort properties in an order of your choosing, making your CSS code easier to scan and comprehend.

/* example.css */
.color {
  color: red;
  background-color: blue;
}

With the stylelint-order plugin, the properties will be sorted alphabetically:

/* example.css */
.color {
  background-color: blue;
  color: red;
}

The stylelint-a11y plugin helps make accessibility a key part of your dev process, while the stylelint-color-format plugin normalizes all colors to RGB(A) or HSL(A).

Improve Code Quality with Stylelint

Stylelint can also help you transition to newer recommended features like logical properties, which offer a way to describe the layout of web pages in a universal vocabulary that’s unambiguous across different languages.

/* example.css */
.container {
  margin-inline-start: 10px;
  margin-inline-end: 20px;
}

Additionally, plugins like stylelint-declaration-block-no-ignored-properties can catch easy-to-make mistakes, such as properties being ignored when used in conjunction with other property-value combinations.

Common Ways to Use Stylelint

So, how can you incorporate Stylelint into your workflow? Here are a few common ways:

• Use Stylelint and Prettier to lint and format your CSS
• Use VS Code with the Stylelint extension to provide squiggly underlines for errors
• Add the Stylelint plugin to your webpack configuration to lint styles for each build
• Integrate Stylelint into your Vue CLI configuration

By incorporating Stylelint into your workflow, you can save yourself headaches and maintain a high level of code quality. With its advanced features and plugins, Stylelint is an essential tool for any developer looking to take their CSS to the next level.
