In this tutorial, we’ll explore the basics of Sass variables, including how to create variables, reference them in your code, perform operations on variables, and use variables within other variables. By the end of this tutorial, you should understand how to use Sass variables to simplify your CSS code and create more efficient maintainable designs.
Variables allow you to store values, such as colors, font sizes, or spacing and reference them throughout your Sass code. This means that you can easily change the value of a property across your entire codebase by updating the value of a single variable. Variables can also be used within other variables, making it easy to create complex designs and maintain a consistent style across your website or application.
To create a variable, use the $ symbol followed by the variable name and the value you want to store. For example, if you’re going to make a variable for the primary color of your website, you could write ;
$primary-color: #007bff;This sets the value of $primary-color to the hexadecimal color code #007bff.
To use the variable, you can reference it in your Sass file using the same syntax as a regular CSS property. For example, if you want to use the $primary-color variable as the background color for a button, you could write;
button {
background-color: $primary-color;
}This sets the background color of all button elements to the value of $primary color.
You can also perform operations on variables. For example, you might want to create a variable for a darker version of your primary color. To do this, you can use the darken() function;
$dark-primary-color: darken($primary-color, 10%);This sets the value of $dark-primary-color to 10% darker than the value of $primary-color.
Finally, you can also use variables within other variables. For example, you might want to create a variable for the border radius of your buttons, and then use that variable to set the border radius of other elements;
$button-border-radius: 5px;
button {
border-radius: $button-border-radius;
}
input[type="text"] {
border-radius: $button-border-radius / 2;
}This sets the border radius of all button elements to 5px, and the border radius of all input elements with a type attribute of “text” to half of that value ( 2.5px ).
Conclusion
Sass variables allow you to store values that you’ll use throughout your CSS and reference them with ease. By using variables, you can create consistent designs and easily change the value of a property across your entire codebase by updating the value of a single variable. You can also perform operations on variables, such as adjusting their brightness or combining them with other values and use them within other variables to create more complex designs. By using Sass variables effectively, you can make your CSS code more organized, efficient, and maintainable.
