Pros
Pro Fast
PostCSS is 3-30 times faster than Sass (including libsass), Less, and Stylus
Pro Flexible
PostCSS allows you to opt-in to the features you need with plugins. This allows you to set it up to behave exactly like Sass, with nesting, mixing, extends, and more. On the other hand, it allows you to use plugins by themselves for things like auto-prefixing, minification, and more. You can even set up your own custom "stack" of plugins to do exactly what you like.
Pro Doesn't force designers to learn a new syntax
Rather than learn a different syntax, PostCSS allows you to write in pure CSS.
Pro JavaScript-based out of the box
Since it's basically CSS extended through JavaScript it works in the browser directly without the need to compile it beforehand.
Pro Intuitive selectors
It uses native CSS property:value selectors like color:blue or font-weight:bold as a selector.
Pro Selectors minification
It shrinks long selectors such as font-weight:bold to _ab12.
Pro Small CSS chunks
- CSS can be generated for each file, page, layout or component separately.
- Selector is generated only once and reused when possible.
Pro On demand generated CSS
It can generate CSS on demand for example inside the express request.
Pro No dependencies required
It doesn't require any post or pre processor.
Pro Seamless integration
It can be easily integrated into the Nuxt.js, Next.js. It works well along with Webpack, Rollup and Vite.js. The CSS can be generated easily for Symfony, Nette or Laravel.
Pro Dynamic screens
Screens can be combined using logical operangs like sm&&tolg, xl||landscape and lg&&dark. The value for media queries can be dynamic like minw640px.
Cons
Con Harder to install and keep working
The immense flexibility of PostCSS plus its current rapid evolution makes it harder to install, configure and keep running than the more monolithic and mature preprocessors.
Con Outdatet, plugins are often based on different postcss versions and don't work together properly
Con Some plugins need to run in a certain order
Some plugins can only work if initialized after some other plugins. For example, transforming and applying CSS variables needs to run before running a plugin which uses these variables inside conditional transformations.
