Challenge: Create Reusable CSS with Mixins

Link to the challenge:

When you are including your mixin, you don’t need to use your variable name, just type in the property value like it’s normal css. So example

/* I created a mixin for backdrop-filter */
                                       ↓↓↓↓↓↓/* This is just a parameter */
@mixin backdrop-filter ($filter){
  -webkit-backdrop-filter: $radius;
  -moz-backdrop-filter: $radius;
  -ms-backdrop-filter: $radius;
  backdrop-filter: $radius;

/* Then I'm going to include it in my paragraph */
p {
  @include backdrop-filter(blur(4x));
