ITCSS Cascading Style Sheets
Inverted Triangle CSS (ITCSS) is a modular, scalable and maintainable approach to writing CSS that prioritizes specificity and helps avoid CSS bloat.
#What is ITCSS?
ITCSS is a methodology for organizing CSS code that helps developers create more scalable and maintainable stylesheets. This approach aims to address some of the challenges of traditional CSS, such as global namespace pollution, specificity issues, and poor performance.
#ITCSS Key Features
Most-recognizable ITCSS features include:
- ITCSS divides CSS code into layers based on the specificity and scope of selectors, starting with the most generic styles at the top and moving to the most specific styles at the bottom.
- It promotes the use of reusable and modular CSS components, with styles that are scoped to specific components and can be easily reused across different parts of the application.
- ITCSS encourages the use of variables and mixins to help developers create consistent and maintainable styles, with support for theming and customization.
- It provides a clear and consistent structure for CSS code, making it easier for developers to understand and maintain, even as the codebase grows and evolves.
- ITCSS supports the use of CSS preprocessors, such as Sass and Less, to help streamline the development process and reduce code duplication.
- It promotes performance optimization, with a focus on reducing the size of the CSS file and minimizing the use of complex selectors.
- ITCSS has a variety of use cases, including:
