What does sass mean when vue creates a project?

Vue is an open source JavaScript framework for building user interfaces. It provides functions such as componentization, two-way data binding, and modularization, allowing developers to build single-page applications (SPA) and complex user interfaces more easily and quickly.

When creating a project using Vue, you will often see the option to use Sass. So, what does Sass mean?

Sass is a CSS preprocessor that extends the CSS language to better organize and manage CSS files. Using Sass makes it easier to write stylesheets, making your project more maintainable and scalable.

Specifically, Sass provides the following advantages:

1. Variables: Global variables can be defined for easy use throughout the project, reducing duplicate code in style sheets, and Allows quick changes to the values ​​of certain properties.
2. Nesting rules: You can nest selectors in CSS just like HTML tag nesting, thereby simplifying the code hierarchy and improving code readability.
3. Modularization: Sass can merge multiple CSS files into one file, thereby reducing the number of HTTP requests and improving page performance.
4. Mixin: Sass’s Mixin is similar to the function in CSS and can reuse some commonly used styles.
5. Inheritance: Sass’s inheritance function allows some selectors to inherit the properties of other selectors.

Using Sass in Vue can improve the maintainability and readability of the project style sheet. At the same time, Sass also supports custom functions and plug-ins, which can provide more scalability for projects.

In short, Sass is a very practical CSS preprocessor that can improve the readability, maintainability and scalability of CSS code. Choosing to use Sass when creating a Vue project can improve the efficiency and quality of the project.
