css - 如何保持我的图标字体上的链接和悬停效果与 CSS 隔离

Question

我有一个自定义字体，用于在我的网页上嵌入人口统计图标，附加信息存储在每个图标的“data-msg”元素周围的链接中。问题是，如果不使用链接属性的通用 CSS 分配，我似乎无法为这些鼠标悬停消息定义 CSS。这使得页面上的所有链接看起来都很奇怪。

如何将 CSS 效果限制在这些图标上？

我已经在 jsfiddle 上为我的问题创建了一个工作示例(即使这是一个纯 css 问题):http://jsfiddle.net/V6vpM/1/

代码如下:

CSS

@font-face {
font-family: 'unicorns';
src: url('http://djotjog.com/font/unicorns.eot');   
src: url('http://djotjog.com/font/unicorns.woff') format('woff'),         
url('http://djotjog.com/font/unicorns.svg#unicorns') format('svg'),
url('http://djotjog.com/font/unicorns.ttf') format('truetype'),
url('http://djotjog.com/font/unicorns.eot?#iefix') format('embedded-opentype');
}

.icon:before {
    font-family: "unicorns", sans-serif !important;
    -webkit-font-smoothing: antialiased;
    -o-transform: scale(1);
}
.boy:before {content: "a";}
.girl:before {content: "b";}
.teen_boy:before {content: "c";}
.teen_girl:before {content: "d";}
.middle_aged_man:before {content: "e";}
.middle_aged_woman:before {content: "f";}

.food_shelter:before {content: "i";}
.phys_need:before {content: "h";}
.security:before {content: "s";}
.family:before {content: "j";}
.knowledge:before {content: "k";}
.respect:before {content: "r";}
.creativity:before {content: "q";}
.self_esteem:before {content: "n";}
.freedom:before {content: "m";}
.fun:before {content: "p";}


.icon-green:before {color: #008000;}
.icon-green-yellow:before {color: #a3b900;}
.icon-yellow:before {color: #e9b800;}
.icon-yellow-red:before {color: #cc6600;}
.icon-red:before {color: #cc0000;}
.icon-pink:before {color: #ff99ff;}
.icon-blue:before {color: #879aaf;}
.icon-gg-green:before {color: #a3b900;}
.icon-orange:before {color: #db8600;}
.icon-brown:before {color: #534400;}
.icon-bright-blue:before {color: #6590AF;}
.icon-black:before {color: #000000;}
.icon-grey:before {color: #505050;}

.icon-5:before {font-size: 5px; margin-right: 1px;} 
.icon-9:before {font-size: 9px; margin-right: 2px;} 
.icon-10:before {font-size: 10px; margin-right: 2px;}
.icon-11:before {font-size: 11px; margin-right: 2px;}
.icon-12:before {font-size: 12px; margin-right: 2px;}
.icon-14:before {font-size: 14px; margin-right: 2px;}
.icon-16:before {font-size: 16px; margin-right: 2px;}
.icon-18:before {font-size: 18px; margin-right: 3px;}
.icon-24:before {font-size: 24px; margin-right: 5px; line-height: 100px;}
.icon-30:before {font-size: 30px; margin-right: 5px;}
.icon-36:before {font-size: 36px; margin-right: 5px;}
.icon-42:before {font-size: 42px; margin-right: 5px;}
.icon-48:before {font-size: 48px; margin-right: 5px; line-height: 100px;}
.icon-54:before {font-size: 54px; margin-right: 5px; line-height: 100px;}
.icon-60:before {font-size: 60px; margin-right: 5px;}
.icon-72:before {font-size: 72px; margin-right: 5px; line-height: 100px;}
.icon-96:before {font-size: 96px; margin-right: 5px; line-height: 100px;}  
.icon-128:before {font-size: 128px; margin-right: 5px; line-height: 130px;}  

CSS -- 这是需要在类中的部分，但是当我这样做时，它会破坏鼠标悬停效果:

a {
position:relative;
  text-decoration:none;
  font-size:x-small;
}
 a:before, a:after {
  bottom:0;
  display:none;
  position:absolute;
}
a:before {
  border-top:1em solid #534400;
  border-left:5px solid transparent;
  border-right:5px solid transparent;
  content:"";
  left:5px;
  margin-bottom:1em;
}
 a:after {
  background-color:#dddddd;
  border-radius:7px;
  color:#534400;        
  content:attr(data-msg);
  left:0;
  margin-bottom:6em;
  padding:7px 7px;
  white-space:pre-wrap;
}       
 a:hover:after,
 a:hover:before {
  display:block;
}

这是 HTML:

<a href="" data-msg="The 0% of stories related to girls, 16 and under were fewer than observed in stories overall. (0.0048/0.05= 0.1)"><span class="icon girl icon-green icon-18 msg"></span></a>
<a href="" data-msg="The 0% of stories related to boys, 16 and under were fewer than observed in stories overall. (0.0048/0.06= 0.08)"><span class="icon boy icon-red icon-18 msg"></span></a>
<a href="" data-msg="The 28% of stories related to girls, age 17 to 30 were about the same as observed in stories overall. (0.2837/0.25= 1.13)"><span class="icon teen_girl icon-red icon-48"></span></a>
<a href="" data-msg="The 25% of stories related to boys, age 17 to 30 were about the same as observed in stories overall. (0.25/0.33= 0.76)"><span class="icon teen_boy icon-green icon-48"></span></a>
<a href="/c/stest?group_select=112&q122=%5B%2731-45%27%2C+%2746-60%27%2C+%27Over+60%27%5D&verbose=complete&submit=Fetch+stories%21&q10=female" data-msg="The 24% of stories related to middle-aged women over 30 were more than observed in stories overall. (0.2452/0.16= 1.53)" ><span class="icon middle_aged_woman icon-green-yellow icon-72 msg"></span></a>
<a href="" data-msg="The 15% of stories related to middle-aged men over 30 were about the same as observed in stories overall. (0.1587/0.16= 0.99)"><span class="icon middle_aged_man icon-green-yellow icon-48"></span></a>

Answer 1

我会创建一个 js 文件并让它更改 data-msg 的值属性，然后您可以将该文件引用回您的 html 页面。

例如:

为您拥有的第一个a 添加一个类

<a href="" class="first notation"><span class="icon girl icon-green icon-18 msg"></span></a>

然后通过js改变data-msg

$(document).ready(function () {
    $(".first").attr("data-msg", "some text");
});

你必须包含JQuery，你可以从here得到它

不要忘记将 css 更新为 a.notation 而不是 a。 Here you go
