使用CSS将背景图像添加到按钮

Question

我正在尝试将背景图像添加到已具有背景颜色的按钮(或具有相同类的链接).

这是jsfiddle:http://jsfiddle.net/BNvke/

该按钮本身看起来很棒,但我试图这样做,以便如果我添加某个类,将调整填充并显示背景图像,但图像不显示.这是CSS/HTML:

.button {
padding: 10px; 
margin-right: 8px;
margin-bottom:10px;
font-family: Arial, Tahoma, Verdana, FreeSans, sans-serif;
text-shadow:0 1px 1px rgba(0, 0, 0, 0.25);
display: inline-block;
white-space: nowrap;
line-height:1em;
position:relative;
outline: none;
overflow: visible;
cursor: pointer;
border-radius: 4px;
-moz-border-radius: 4px; 
-webkit-border-radius:4px; 
box-shadow:1px 1px 2px 0 #CCCCCC;
-moz-box-shadow: 1px 1px 2px 0 #CCCCCC;
-webkit-box-shadow: 1px 1px 2px 0 #CCCCCC;
}

.button_blue {
border: 1px solid #305875;
color: #FBFBFB;
background-color: #3D6E97;
}

.button_blue:hover {
color: #FBFBFB;
opacity:0.9; 
filter:alpha(opacity=90);        
}

.button_about { 
background-image: url(http://i47.tinypic.com/2ni0ahd.png) 3px 5px no-repeat;
padding-left: 35px;
padding-right: 15px;
}?

-

<p><a class="button button_blue">Without Background</a></p>

<p><a class="button button_blue button_about">With Background</a></p>?

如何才能显示该背景图像？

Answer 1

见http://jsfiddle.net/BNvke/1/

只是改变

background-image url(http://i47.tinypic.com/2ni0ahd.png) 3px 5px no-repeat;

同

background: url(http://i47.tinypic.com/2ni0ahd.png) 3px 5px no-repeat;

并向上移动最后一条规则,以便可以在级联上应用有关已background-color定义的规则.button_blue
