I've written this code, but it does not work. What is my problem?
.class { margin:20px; :hover { color:yellow; } } 0 2 Answers
For concatenating selectors together when nesting, you need to use the parent selector (&):
.class { margin:20px; &:hover { color:yellow; }
} 1 You can easily debug such things when you go through the generated CSS. In this case the pseudo-selector after conversion has to be attached to the class. Which is not the case. Use "&".
.class { margin:20px; &:hover { color:yellow; }
}
