CSS Sass Basics Improve Your Workflow with Sass Write Nested Selectors

``` .icn { font-size:1.25em &-success { color:green } } ```

I thought we can make '.icn-success' after compile them, but system said it doesn't work. Please tell me some tips to solve this question. Thanks.

.banner {
  padding: 1em;
  background-color: lightgrey;
    .button {
    font-size: 1.5em;

.icn {
    &-success {

Hi Ryohei, have you tried adding a semicolon after your font size and color styles?

.icn { font-size:1.25em; &-success { color:green; } }

Stuart, Thank you, I was able to solve the problem.
