一组属性的多个CSS选择器

Question

如何为一组CSS属性选择多个元素？

例如，我该如何正确地执行此操作？：

.facebook:hover,twitter:hover {
    padding-left: 50px;
    opacity: 1.0;
    -webkit-transition: all .7s ease;
    -moz-transition: all .7s ease;
    -ms-transition: all .7s ease;
    -o-transition: all .7s ease;
    transition: all .7s ease;
    border-radius: 0px 10px 10px 0px;
}

Answer 1

这是可能的。你在twitter之前只缺少.facebook:hover, .twitter:hover { padding-left: 50px; opacity: 1.0; -webkit-transition: all .7s ease; -moz-transition: all .7s ease; -ms-transition: all .7s ease; -o-transition: all .7s ease; transition: all .7s ease; border-radius: 0px 10px 10px 0px; } ：

Date()

Answer 2

你必须在twitter课程之前使用 dot（。）。

.facebook:hover, .twitter:hover {
padding-left: 50px;
opacity: 1.0;
-webkit-transition: all .7s ease;
-moz-transition: all .7s ease;
-ms-transition: all .7s ease;
-o-transition: all .7s ease;
transition: all .7s ease;
border-radius: 0px 10px 10px 0px;
}
