@include vs @extend in SASS (original) (raw)
Last Updated : 12 Jul, 2025
@include keyword is used to include the code written in a mixin block. @mixin is used to group css code that has to be reused a no of times. Whereas the @extend is used in SASS to inherit(share) the properties from another css selector. @extend is most useful when the elements are almost same or identical. The main difference between the two is in their compiled CSS file.
- @include example SCSS file: css
@mixin text { color: black; font-size: 30px; font-weight: bold; } .hello{ @include text; } .world{ @include text; }Mixin duplicates the styles over all classes in the CSS.Compiles CSS file:
.hello{
color: black;
font-size: 30px;
font-weight: bold;
}
.world{
color: black;
font-size: 30px;
font-weight: bold;
}
Mixin can also accept parameters if required, whereas this is not possible with extend. for more details of @mixin visit here - @extend example: Here in this example, the two buttons will share the general properties for a button but they differ in background color only so using extend in cases like these where the elements are almost the same and only differ some properties using @extend is a good idea.SCSS file: css
%button-format { padding: 10px 20px; border-radius: 15px; color: black; } .toolbar-button { @extend %button-format; background-color: lightpink; &:hover { background-color: rgb(155, 106, 114); } } .status-bar-button { @extend %button-format; background-color: lightblue; &:hover { background-color: blue; } }compiled CSS file:
.status-bar-button, .toolbar-button {
padding: 10px 20px;
border-radius: 15px;
color: black;
}
.toolbar-button {
background-color: lightpink;
}
.toolbar-button:hover {
background-color: #9b6a72;
}
.status-bar-button {
background-color: lightblue;
}
.status-bar-button:hover {
background-color: blue;
}
**Conclusion:**SASS is a fantastic style sheet language and its both features @include and @extend both have pros and cons despite this, if used in the exact situation these can prove to be the best tools of SASS.
