Understanding the Two Syntaxes of Sass: SCSS and Indented Syntax

Sass, which stands for Syntactically Awesome Style Sheets, is a CSS preprocessor script that makes CSS-based stylesheets more structured, reusable, and easier to maintain. It's a useful tool for web designers and developers, offering improved functionality compared to standard CSS.

One of the noteworthy elements of Sass is its dual syntax. There are two types of syntax available when using Sass: SCSS and indented syntax, sometimes referred to as just "Sass".

SCSS Syntax

SCSS, standing for Sassy CSS, closely mirrors CSS syntax. This syntax uses semicolons and curly braces, much like CSS does. This makes SCSS a lot more similar to regular CSS, and is probably the easier syntax to pick up if you're already familiar with CSS.

Here's an example of the SCSS syntax:

.div {
  background-color: lightblue;
  &:hover {
    background-color: lightgray;
  }
}

Indented Syntax (Sass)

In contrast, the original indented syntax (what some might call "Sass syntax") relies on indentation rather than semicolons and braces. Some developers argue this syntax is cleaner and more concise compared to SCSS, however, it has a steeper learning curve for those experienced with CSS.

Here's an example:

.div
  background-color: lightblue
  &:hover
    background-color: lightgray

By offering SCSS and the indented syntax, Sass provides developers with flexibility in code formatting. But it's important to note that most new users of Sass tend to use the SCSS syntax due to its close resemblance to CSS. This makes transitioning to the use of a CSS preprocessor like Sass less daunting, and aids in building more complex, well-structured, and reusable stylesheet code.

Understanding the different syntaxes used in Sass is the first step in effectively using this powerful tool for your web design projects. You can choose the version most comfortable to you, but being fluent in both will make your stylesheet management more versatile and robust.
