假设我有一些这样的 HTML:
<!DOCTYPE HTML>
<html lang="en-US">
<head>
<meta charset="UTF-8">
<title></title>
<link rel="stylesheet" href="css/styles.css"></link>
</head>
<body>
This is a test
<a class="ribbons-sprite ribbons-exclusive" href="#">Exclusive</a>
<a class="ribbons-sprite ribbons-featured" href="#">Featured</a>
</body>
</html>
我有一些像这样的 SASS (SCSS):
@import "compass/utilities";
@import "ribbons/*.png";
@include all-ribbons-sprites(true);
.ribbons-sprite {
display: inline-block;
text-indent: -9999px;
}
输出的 CSS 是这样的:
.ribbons-sprite, .ribbons-exclusive, .ribbons-featured {
background: url('../images/ribbons-scfb85024fb.png') no-repeat;
}
.ribbons-exclusive {
background-position: 0 -38px;
height: 59px;
width: 59px;
}
.ribbons-featured {
background-position: 0 0;
height: 38px;
width: 70px;
}
.ribbons-sprite, .ribbons-exclusive, .ribbons-featured {
display: inline-block;
text-indent: -9999px;
}
为什么最后一个选择器列表包含所有类,而不仅仅是“.ribbons-sprite”?我可以看看我的精灵中是否有更多的项目,它会变得不必要地臃肿。只有当我使用精灵生成器时才会出现这种情况。如果我删除此行,则内联块和文本缩进行就在共享类名选择器下方。这是我期望的 CSS 输出:
.ribbons-sprite {
background: url('../images/ribbons-scfb85024fb.png') no-repeat;
display: inline-block;
text-indent: -9999px;
}
.ribbons-exclusive {
background-position: 0 -38px;
height: 59px;
width: 59px;
}
.ribbons-featured {
background-position: 0 0;
height: 38px;
width: 70px;
}
