Autoprefixer vs Sass: What are the differences?

1. Autoprefixer Features: Autoprefixer is a post-processor that parses CSS files and adds necessary vendor prefixes. It automatically adds vendor prefixes to CSS properties based on the latest specifications, ensuring compatibility across different browsers. It does not require any additional syntax or code changes, making it a convenient tool for developers.
2. Sass Features: Sass, on the other hand, is a preprocessor that extends the functionality of CSS by introducing features like variables, nesting, mixins, and functions. It allows developers to write more maintainable and reusable CSS code by enabling them to use variables for color schemes, nest selectors for better organization, and create reusable code snippets using mixins and functions.
3. Compilation Process: When it comes to the compilation process, Autoprefixer is a post-processor, which means it is applied after the CSS has been generated. It analyzes the CSS code and adds prefixes without modifying the source code. Sass, on the other hand, is a preprocessor that compiles Sass code into CSS code before it is used in a project. It requires a separate compilation step to generate the final CSS file.
4. Language Syntax: Autoprefixer works directly with CSS, meaning it follows the same syntax and rules as CSS. It doesn't introduce any new syntax or require any additional learning curve. Sass, however, has its own syntax that is similar to CSS but with some additional features. Developers need to learn the Sass syntax and follow its rules in order to use it effectively.
5. Browser Compatibility: Autoprefixer focuses on ensuring compatibility across different browsers by automatically adding vendor prefixes. It analyzes the browser compatibility data and adds the necessary prefixes accordingly. Sass, on the other hand, does not directly address browser compatibility. It provides features like variables and mixins that can be used to write more compatible CSS, but it doesn't handle the prefixing aspect directly.
6. Use Cases: Autoprefixer is primarily used to improve browser compatibility by adding necessary vendor prefixes. It is a useful tool for web developers who want to ensure their CSS works seamlessly across different browsers. Sass, on the other hand, is used to enhance the development process by introducing features that make CSS code more maintainable and reusable. It is commonly used in larger projects where managing and maintaining CSS code becomes more complex.

In Summary, Autoprefixer focuses on browser compatibility by automatically adding vendor prefixes, while Sass extends the functionality of CSS and enhances the development process with features like variables, nesting, and mixins.

Sass

Stylus

PostCSS

Originally, I was going to start using Sass with Parcel, but then I learned about Stylus, which looked interesting because it can get the property values of something directly instead of through variables, and PostCSS, which looked interesting because you can customize your Pre/Post-processing. Which tool would you recommend?

Detailed Comparison

Sass	Autoprefixer
Sass is an extension of CSS3, adding nested rules, variables, mixins, selector inheritance, and more. It's translated to well-formatted, standard CSS using the command line tool or a web-framework plugin.	It is a CSS post processor. It combs through compiled CSS files to add or remove vendor prefixes like -webkit and -moz after checking the code.

What are some alternatives to Sass, Autoprefixer?

Less

Less is a CSS pre-processor, meaning that it extends the CSS language, adding features that allow variables, mixins, functions and many other techniques that allow you to make CSS that is more maintainable, themable and extendable.

Stylus

Stylus is a revolutionary new language, providing an efficient, dynamic, and expressive way to generate CSS. Supporting both an indented syntax and regular CSS style.

PostCSS

PostCSS is a tool for transforming CSS with JS plugins. These plugins can support variables and mixins, transpile future CSS syntax, inline images, and more.

Bourbon

Bourbon is a library of pure sass mixins that are designed to be simple and easy to use. No configuration required. The mixins aim to be as vanilla as possible, meaning they should be as close to the original CSS syntax as possible.

Compass

The compass core framework is a design-agnostic framework that provides common code that would otherwise be duplicated across other frameworks and extensions.

CSS Modules

It is a CSS file in which all class names and animation names are scoped locally by default. The key words here are scoped locally. With this, your CSS class names become similar to local variables in JavaScript. It goes into the compiler, and CSS comes out the other side.

astroturf

It lets you write CSS in your JavaScript files without adding any runtime layer, and with your existing CSS processing pipeline.

PreCSS

It combines Sass-like syntactical sugar — like variables, conditionals, and iterators — with emerging CSS features — like logical and custom properties, media query ranges, and image sets.

Animate.css

It is a bunch of cool, fun, and cross-browser animations for you to use in your projects. Great for emphasis, home pages, sliders, and general just-add-water-awesomeness.
