In the realm of web development, maintenance of clean and efficient CSS (Cascading Style Sheets) is crucial. Enter CSS Checker – a tool designed to streamline your CSS styles by checking for duplications and finding similarities in classes. Let’s explore how to use this tool and tackle common issues that may arise in the process.

Purpose of CSS Checker

CSS Checker helps in reducing redundancy in your CSS files, saving time and enhancing performance. By checking for similarities, duplicative styles, and unused CSS selectors, it clears the clutter from your stylesheet, facilitating smoother local development and automation in Continuous Integration (CI) environments.

Installation: Get Started

To install CSS Checker, you have two options:

• Using Go: Run go install github.com/ruilisi/css-checker@latest (For Go versions before 1.17, use go get github.com/ruilisi/css-checker).
• Using npm: Install globally with npm install -g css-checker-kit.

Usage Instructions

After installation, you can run CSS Checker in the following way:

• Navigate to your project directory that contains CSS files using cd PROJECT_WITH_CSS_FILES.
• Then execute css-checker to start the analysis.

You can also enable a styled components check by running: css-checker -styled.

Understanding the Output with an Analogy

Think of CSS Checker as a neat housekeeper for your web project. When you invite this housekeeper in, they don’t just clean the surfaces—they examine every corner, identifying every duplicate item (similar CSS classes) and unused clutter (unused CSS). They even suggest consolidating your color palettes (colors check) to make your project feel more organized. The advanced features are like having a personal organizer who helps you find spots where you can store items more cleverly (like combining similar styles into one). This process results in a more efficient living space (your CSS files), which ultimately translates into better performance for your website!

Troubleshooting Tips

Here are some common issues you might encounter while using CSS Checker, along with their possible solutions:

• Issue: PowerShell outputs are messy or hard to read.
  Solution: To activate ANSI escape sequences in PowerShell, run the command: Set-ItemProperty HKCU:Console VirtualTerminalLevel -Type DWORD 1 and then restart PowerShell.
• Issue: CSS Checker fails to find unused classes.
  Solution: Ensure that you use the alpha feature by running css-checker -unused
• Issue: Configuration issues.
  Solution: Make sure your css-checker.yaml file is correctly placed in your project path, and parameters are set correctly as outlined in the documentation.

Advanced Features

CSS Checker includes several advanced functionalities:

• Check styled components without verifying CSS files: css-checker -css=false -styled
• Search for paths you want to ignore in the analysis by modifying the ignores list in your config file.
