Sass Variables

Sass variables are used to store information that can be reused throughout the stylesheet when you need. You can store things like colors, font stacks, or any CSS value according to your future reusability.

The $ symbol is used to make something a variable. See the syntax.

SCSS Syntax:

Equivalent Sass Syntax:

When it is processed, it takes the variables we define for the $font-stack and $primary-color and creates a normal CSS with the variable values placed in the CSS.

CSS after processing:


Let's take an example to see the use of Sass variable. We have an HTML file named "simple.html" having the following code:

File: simple.html

Create a SCSS file named "simple.scss", having the following code:

File: simple.scss

Put the both file inside the root folder.

Now, open command prompt and run the watch command to tell SASS to watch the file and update the CSS whenever SASS file is changed.

Execute the following code: sass --watch simple.scss:simple.css

It will create a normal CSS file named "simple.css" in the same directory automatically.

For example:

Sass Variable1

The created CSS file "simple.css" contains the following code:

Now, execute the above html file, it will read the CSS value.


Sass Variable2

In the above example, you can see that The HTML file read the CSS and accordingly display the content in Helvetica font and pink color.
