New to sass, expecting expected selector
提问by John Smith
Im new to sass and tried some code:
我刚接触 sass 并尝试了一些代码：
$blue: #3bbfce
$margin: 16px
.content-navigation
border-color: $blue
color: darken($blue, 9%)
.border
padding: $margin / 2
margin: $margin / 2
border-color: $blue
But now in my rails app i get this error:
但现在在我的 rails 应用程序中，我收到此错误：
Invalid CSS after "$margin": expected selector or at-rule, was ": 16px"
Whats wrong?
怎么了？
Now i tried something with zurb:
现在我用 zurb 尝试了一些东西：
.your-class-name {
@include button;
@include dropdown-button($padding, $pip-color, $base-style);
}
But now i get the error
但现在我得到了错误
Undefined mixin 'dropdown-button'.

You're missing semicolons after your style declarations. You also need to encapsulate selector declarations within curly brackets:
您在样式声明后缺少分号。您还需要将选择器声明封装在大括号中：
$blue: #3bbfce;
$margin: 16px;
.content-navigation {
border-color: $blue;
color: darken($blue, 9%);
}
.border {
padding: $margin / 2;
margin: $margin / 2;
border-color: $blue;
}
You might like to read over this primerfrom the creators of SASS.
