SCSS (short for "Sassy CSS") is a CSS preprocessor. A CSS preprocessor is a tool that allows you to write styles for your website using a special syntax that is then compiled into regular CSS that can be used in a web browser.
SCSS is an extension of the CSS syntax, and it uses curly braces and semicolons like regular CSS. It allows you to use features such as variables, nested selectors, mixins, and other features that make it easier to write and maintain CSS styles. SCSS also supports features such as functions and loops, which are not present in regular CSS.
Here is an example of SCSS syntax:
$font-stack: Helvetica, sans-serif;
$primary-color: #333;
body {
font: 100% $font-stack;
color: $primary-color;
}
In this example, we define two variables: $font-stack, which holds the value of a font stack, and $primary-color, which holds the value of a color. We then use these variables in the body selector to set the font and color of the body element.
SCSS is required when you want to use features that are not available in regular CSS, such as variables and mixins. It is particularly useful when you are working on a large or complex project and need to reuse styles or customize them for different environments or devices.
To use SCSS, you need to install a SCSS compiler, such as node-sass or sass-loader, and configure your build process to compile your SCSS files into CSS files. You can then include the generated CSS files in your HTML files using the link element.
I hope this helps to give you an understanding of what SCSS is and why it is useful! Let me know if you have any questions or need further assistance.
