问题描述
我试图列出社交按钮。当一个按钮悬停时亮起,其他按钮应该变暗。我把它部分地工作了。当第一个按钮悬停时,所有的工作都可以正常工作,但是当其他按钮悬停时,它会发生故障。我认为这是因为所有后面的列表项都是第一个和:hover
事件的兄弟,不能导致以前的元素改变样式。
有没有人有任何想法如何让这个工作?
这里的代码():

I am trying to make a list of social buttons. When one button is hovered it lights up, and the other buttons should darken.
I got it to work partially. When the first button is hovered all works fine, but it is malfunctioning when the other buttons are hovered. I think this happens because all the latter list items are siblings of the first and the :hover
event can't cause previous elements to change style.Does anyone have any thoughts on how to get this to work?
Here's the code (jsFiddle live demo):
<div id="bg">
<ul id="social_buttons">
<li id="item_1"><img src="http://i43.tinypic.com/104rasi.png"></li>
<li id="item_2"><img src="http://i43.tinypic.com/k4tide.png"></li>
<li id="item_3"><img src="http://i44.tinypic.com/2ry0gt3.png"></li>
</ul>
</div>
#bg {
height: 100px;
width: 215px;
background-color: black;
position: relative;
}
#social_buttons img {
width: 24px;
height: 24px;
-webkit-transition:all 0.2s ease-in-out;
-moz-transition:all 0.2s ease-in-out;
-o-transition:all 0.2s ease-in-out;
transition:all 0.2s ease-in-out;
}
#social_buttons {
list-style-type: none;
position: absolute;
top: 20px;
right: 70px;
-webkit-transition:all 0.2s ease-in-out;
-moz-transition:all 0.2s ease-in-out;
-o-transition:all 0.2s ease-in-out;
transition:all 0.2s ease-in-out;
}
#social_buttons li {
float: left;
margin-right: 2px;
-webkit-transition:all 0.2s ease-in-out;
-moz-transition:all 0.2s ease-in-out;
-o-transition:all 0.2s ease-in-out;
transition:all 0.2s ease-in-out;
}
/* puur css3 multiple hover animaties */
#item_1 {
opacity: 0.8;
}
#item_1:hover ~ #item_2, :hover ~ #item_3 {
opacity: 0.5;
}
#item_1:hover {
opacity: 0.9;
}
#item_2 {
opacity: 0.8;
}
#item_2:hover ~ #item_1, :hover ~ #item_3 {
opacity: 0.5;
}
#item_2:hover {
opacity: 0.9;
}
#item_3 {
opacity: 0.8;
}
#item_3:hover ~ #item_1, :hover ~ #item_2 {
opacity: 0.5;
}
#item_3:hover {
opacity: 0.9;
}
This is actually pretty easy with the right selectors
ul li {
opacity: 0.8;
}
ul:hover li {
opacity: 0.5;
}
ul li:hover {
opacity: 1.0;
}
