The example of stylus getting started is detailed

Stylus is an expressive, dynamic, and robust CSS preprocessor that lets you write CSS in a more efficient and concise way. Similar to other CSS preprocessors such as Sass and Less, Stylus provides features such as variables, mixins, functions, conditional statements, and loops to make CSS development more flexible and powerful.

Install Stylus

First, you need to install Node.js in your development environment, as Stylus is installed through Node.js' package manager npm.

The command to install Stylus is as follows:

npm install stylus -g

The -g argument is used to install Stylus globally, so you can use it anywhere.

Write code for Stylus

Create a new.styl file, such as style.styl, and you can start writing styles in Stylus syntax. Stylus has a very flexible syntax. You can choose to use indents and colons to organize your code, or you can use braces and semicolons as you would in normal CSS.

Here is a simple example of Stylus code:

border-radius()
  -webkit-border-radius arguments
  border-radius arguments
box
  border-radius 10px

Compile the Stylus code

Once you have written Stylus code, you need to compile it into CSS code for use in web pages. You can do this through command line tools.

On the command line, navigate to the directory where your.styl file is located and run the following command to compile it:

stylus style.styl

This generates a CSS file with the same name (style.css) that contains the compiled CSS code.

You can also specify the output directory using the -o argument:

stylus style.styl -o ./css

This will output the compiled CSS file to the./css directory.

Use Stylus's advanced features

Stylus offers a number of advanced features, including but not limited to:

• Variables: Common values such as colors and fonts can be stored for reuse.
• Mixins: A set of attributes can be included or mixed in from one rule set to another.
• Functions: Blocks of logic code can be defined for reuse.
• Conditional statements and loops: You can apply styles or generate repeated style rules based on conditions.

Example: Using variables and mixing

// Define variable main-color = #333 // Define hybrid border-radius(radius) -webkit-border-radius: radius border-radius: radius // Use variables and blend button background-color: main-color border-radius(5px)

conclusion

Stylus is a powerful CSS preprocessor that makes your style sheet development more efficient and fun. With Stylus, you can write cleaner, modular code by taking advantage of features like variables, blends, functions, and more. The above introduction and examples are just the tip of the iceberg of Stylus's capabilities, and more advanced features and usage can be found in the official Stylus documentation.
