使用&符号时遇到一些困难。如果我这样使用它:
.form-standard {
...
.form--group {
&.has-error {
border-color: $form-error-color;
color: $form-error-color;
.form--feedback::before {content: '*';} // <-- here
&.has-focus {
box-shadow: inset 0 1px 3px rgba(#000, 0.06), 0 0 5px rgba($form-error-color, 0.7);
color: $form-error-color;
}// has-focus
}// has-error
}// form--group
}// form-standard
然后我实现了我想要的,即:
.form-standard .form--group.has-error .form--feedback::before {
content: '*';
}
但是linter抱怨伪元素应该嵌套在它的父类中。我试过这个:
.form-standard {
...
.form--group {
.form--feedback {
clear: left;
font-size: 12px;
margin: 0;
padding: 0;
padding-left: 5px;
.has-error & { //
&::before {content: '*';} // produces same output
} //
&::before { //
.has-error & {content: '*';} // produces same output
} //
}// form--feedback
}// form--group
}// form-standard
但结果并非我想要的结果:
.has-error .form-standard .form--group .form--feedback::before {
content: '*';
}
这是HTML:
<form class="form form-standard" role="form">
<div class="form--group">
<label>category</label>
<input id="category" type="text" name="category">
</div>
</form>
答案 0 :(得分:1)
根据Harry建议将伪元素向下移动一级解决了lint警告并且根本不需要&符号:
&.has-error {
border-color: $form-error-color;
color: $form-error-color;
//.form--feedback::before {content: '*';} // before had a warning
// after
.form--feedback {
&::before {content: '*';}
}
}
