Alternative Options

• Plain HTML:

  html
  Welcome Nyan CSS!
  Please, welcome Nyan CSS!

• Vue.js:

  js
  import Vue from 'vue';
  import Header, Text from './style.css';
  
  const Announcement = {
      components: {
          'custom-header': Header,
          'custom-text': Text,
      },
      template: `
          
  
              Welcome Nyan CSS!
              Please, welcome Nyan CSS!
          
      `,
  };

• Preact:

  jsx
  import h from 'preact';
  import Header, Text from './style.css';
  
  function Announcement() {
      return (
          
  Welcome Nyan CSS!
          Please, welcome Nyan CSS!
      );
  }

Defining Conventions

Nyan CSS follows a simple convention that helps in creating components efficiently.

• Component: Must be in ClassCase, e.g., .FormInput.
• Boolean Prop: Uses camelCase for class names, e.g., .FormInput-autoFocus.
• Enum Prop: Extensions in camelCase, e.g., .FormInput-borderColor-lightGray.

Troubleshooting Ideas

• Problem with Installation: Ensure that you are following the installation instructions for your specific environment.
• Rendering Issues: Double-check your component imports and class names for typos. Inconsistent naming can lead to components not rendering as expected.
• Props not working: Ensure you’re passing the correct props and that they match the expected naming convention.
