Inheritance and Extends
In this lesson, we'll be looking at how to implement inheritance with the extends directive.
We'll cover the following
Definition #
Another great feature of Sass is inheritance. We implement this using the @extend
directive.
Inheritance is a feature of SASS that allows multiple classes to share a common set of properties with one another.
Example #
Some typical CSS code for styling a button:
.button {
background-color: #0000FF; // Blue
border: none;
color: white;
padding: 15px 32px;
text-align: center;
text-decoration: none;
display: inline-block;
font-size: 1.5rem;
}
If we happen to have a number of buttons on our website, all of which are styled in a similar manner, we would have a good case for inheritance!
We would implement a secondary button via inheritence like so:
.button-secondary {
@extend .button;
background-color: #4CAF50; // Green
}
Our .button-secondary
class will take on all of the properties and values set the .button class
, with the exception of background-color
which we’ve decided to set to green.
