Less extends CSS with dynamic behavior such as variables, mixins, operations and functions. Less runs on both the server-side (with Node. js and Rhino) or client-side (modern browsers only).

Less features and specs

  • Simplifies CSS
    Less extends CSS with dynamic behavior like variables, mixins, operations, and functions, making stylesheets more maintainable and less repetitive.
  • Preprocessing
    Allows developers to write easier and cleaner code which then gets compiled into standard CSS, facilitating better performance and compatibility.
  • Variables and Mixins
    With the ability to use variables and mixins, code becomes modular and reusable, reducing the potential for errors and simplifying updates.
  • Nested Syntax
    Supports nested syntax which allows CSS to be structured in a manner that follows the same visual hierarchy, making it easier to read and understand.
  • Compatibility
    Compatible with all versions of CSS, making it easier to integrate with existing projects and frameworks without breaking them.

Possible disadvantages of Less

  • Learning Curve
    Requires developers to learn new syntax and concepts, which can be a barrier for those who are accustomed to traditional CSS.
  • Compilation Requirement
    Code written in Less needs to be compiled to CSS, adding an extra step in the development process.
  • Performance Overhead
    While not significant, the preprocessing step can add to development time and require additional configuration and tools.
  • Debugging
    Debugging Less can be more challenging compared to plain CSS because source maps need to be set up properly to map the compiled CSS back to the Less files.
  • Dependency
    Relies on Node.js or another JavaScript runtime for compiling the Less code, adding another dependency to the project.

CSS Next features and specs

  • Future CSS Features
    CSS Next allows developers to use the latest CSS syntax and features that may not yet be supported by all browsers, enabling progressive enhancement and future-proofing stylesheets.
  • Simplified Syntax
    By using future CSS features, developers can write more concise and expressive code, making stylesheets easier to read and maintain.
  • Polyfills and Transpilation
    CSS Next automatically provides polyfills and transpiles CSS so that the latest features can be used even in environments that do not yet support them natively.
  • Improved Workflow
    With CSS Next, developers can directly utilize tools that help improve styling workflows, such as variables, custom selectors, and media queries, more conveniently.

Possible disadvantages of CSS Next

  • Dependency on Tooling
    CSS Next requires a build process for transpilation, which adds complexity and dependencies to project setup and maintenance.
  • Potential Performance Overhead
    The polyfills and transpilation process can introduce a performance overhead during development and build times, affecting the speed of initial setup.
  • Limited Support for Older Browsers
    While CSS Next helps bring future features to more browsers, it might not fully support significantly older browsers, necessitating additional fallbacks or workarounds.
  • Project Activity and Maintenance
    Due to changes in the web development landscape and focus shifts, CSS Next might not be actively maintained, potentially leading developers to use alternatives like PostCSS or native CSS features as they become available.

  • PostCSS - my initial experience
    The author of the most popular PostCSS plugin himself recommended the postcss-preset-env over his own creation which is cssnex, and. - Source: dev.to / over 2 years ago
  • Vanilla+PostCSS as an Alternative to SCSS
    Switching from a ready-made tool like Sass or a recommendation package like cssnext (deprecated since 2019) or PostCSS Preset Env (archived in 2022), to the modular PostCSS Preset Env plugin set we can choose a helpful and convenient set of future CSS features beyond the current stable client CSS. - Source: dev.to / about 2 years ago
