What is the meaning of the “@include” in .css Files?

Question

I don\'t understand , what is the meaning of the @include tag in .css files. For Example :

.wrapper {
display: flex;
width: 100%;
@include display(flex);
@in

@includes are a part of SCSS, it's called Mixin. Here is an example:

@mixin border-radius($radius) {
    -webkit-border-radius: $radius;
       -moz-border-radius: $radius;
        -ms-border-radius: $radius;
            border-radius: $radius;
}

.box { @include border-radius(10px); }

@includes are a shortcut to storing especially things like vendor prefixes. The CSS output of the above will be:

.box {
    -webkit-border-radius: 10px;
       -moz-border-radius: 10px;
        -ms-border-radius: 10px;
            border-radius: 10px;
}
