styled-jsx VS less.js

You'd rather use this over tailwind? Na...

styled-jsx -> A library with a lot of similar features like styled-components. Has some extra features here and there.

This isn't a new idea. CSS in JS is obviously a thing, but that usually implies having component code with CSS right alongside it in some sort of JS based syntax. There's also JSS which is a library for writing CSS with JS.

The CSS we'll use for the Gantt chart is included in the starter code. We've used Styled JSX, which comes with Next.js, to write scoped-styled components. There are some global styles in styles/globals.js. These global styles are added to our app in the Layout component in the components folder. The entire app is wrapped in this Layout component in the _app.js file, which is in the pages folder.

Styled JSX is what we're using at work right now, since we're using Next.js and it comes with this out of the box. We're actually using both SCSS modules for static styles and Styled JSX for dynamic styles. It's been great so far.

The previous three methods covered the best styling options if you prefer Utility CSS. But perhaps you are more of a CSS-in-JS kind of person. In which case, Styled-JSX might be up your alley.

LESS [ https://lesscss.org ]

Traditionally CSS lacked features such as variables, nesting, mixins, and functions. This was frustrating for Developers as it often led to CSS quickly becoming complex and cumbersome. In an attempt to make code easier and less repetitive CSS pre-processors were born. You would write CSS in the format the pre-processor understood and, at build time, you'd have some nice CSS. The most common pre-processors these days are Sass, Less, and Stylus. Any examples I give going forward will be about Sass as that's what I'm most familiar with.

In the past, you’d need to rely on pre-processors such as SaSS or Less, but not anymore… Native CSS nesting has landed on all major modern browsers.

Consider using CSS preprocessors like Sass or Less not only for better code organization but also for potential performance improvements.

Extensions of CSS: for example, Sass, Less, Tailwind, CSS Modules, to make stuff look a certain way on your own.

LiveCodes provides many of the commonly used developer tools. These include Monaco editor (that powers VS Code), Prettier, Emmet, Vim/Emacs modes, Babel, TypeScript, SCSS, Less, PostCSS, Jest and Testing Library, among others. All these tools run seamlessly in the browser without any installations or configurations. It feels like a very light-weight version of your own local development environment including the keyboard shortcuts, IntelliSense and code navigation features.

LESS

The CSS Working Group had been aware of the need for CSS variables since its inception in 1997. By the late 2000s, developers had created various workarounds like custom PHP scripts and preprocessors like Less and Sass to compensate for this deficiency.

He could do with LESS

While we may disagree whether Sass is still relevant today, Mayank's case for using Sass in 2022 sums up the many use cases for Sass/SCSS including a timeline from 2006 (Sass) to "2022+" (nesting). Nesting CSS used to one of the few good reasons left to choose Sass, SCSS (or less) in a new web project.
