What is SCSS ?
SCSS (Sass Cascading Style Sheets) is a type of preprocessor for CSS that allows developers to write more efficient and maintainable CSS code. It extends the syntax of CSS with features such as variables, nesting, and functions, which can help reduce code duplication and improve the readability of stylesheets.
Here’s an example of a simple SCSS rule that sets the font size and color of all h1 elements in a web page:
SCSS Code
$base-font-size: 24px;
$base-color: #333333;
h1 {
font-size: $base-font-size;
color: $base-color;
} In this example, we define two variables using the $ syntax: $base-font-size and $base-color. These variables are then used in the font-size and color declarations for the h1 element.
SCSS also supports nesting, which allows us to write more readable and maintainable CSS code by organizing related styles together. Here’s an example of how we might use nesting to define styles for a navigation menu:
nav {
ul {
list-style: none;
margin: 0;
padding: 0;
}
li {
display: inline-block;
margin: 0 10px;
}
a {
color: $base-color;
text-decoration: none;
&:hover {
text-decoration: underline;
}
}
} In this example, we use nesting to define styles for the ul , li , and a elements inside the nav element. The & syntax is used to refer to the parent selector ( a.hover in this case).
SCSS files are typically compiled to standard CSS code using a build tool or command line tool. This allows the browser to interpret the CSS code as normal.
