CSS issue with background button

这个问题已经有了答案：

如何在同一元素上结合背景图像和CSS3渐变？

我有一个按钮，上面有一个渐变。我还需要一个图像箭头放在上面，但当我将它放在背景上并且有两个类的按钮时，它似乎无法工作。下面是一个例子:


.btn{
    background: rgb(0,166,255); /* Old browsers */
    background: -moz-linear-gradient(top,  rgba(0,166,255,1) 0%, rgba(0,166,255,1) 50%, rgba(2,154,236,1) 53%, rgba(2,154,236,1) 100%); /* FF3.6+ */
    background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,rgba(0,166,255,1)), color-stop(50%,rgba(0,166,255,1)), color-stop(53%,rgba(2,154,236,1)), color-stop(100%,rgba(2,154,236,1))); /* Chrome,Safari4+ */
    background: -webkit-linear-gradient(top,  rgba(0,166,255,1) 0%,rgba(0,166,255,1) 50%,rgba(2,154,236,1) 53%,rgba(2,154,236,1) 100%); /* Chrome10+,Safari5.1+ */
    background: -o-linear-gradient(top,  rgba(0,166,255,1) 0%,rgba(0,166,255,1) 50%,rgba(2,154,236,1) 53%,rgba(2,154,236,1) 100%); /* Opera 11.10+ */
    background: -ms-linear-gradient(top,  rgba(0,166,255,1) 0%,rgba(0,166,255,1) 50%,rgba(2,154,236,1) 53%,rgba(2,154,236,1) 100%); /* IE10+ */
    background: linear-gradient(to bottom,  rgba(0,166,255,1) 0%,rgba(0,166,255,1) 50%,rgba(2,154,236,1) 53%,rgba(2,154,236,1) 100%); /* W3C */
    filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#00a6ff', endColorstr='#029aec',GradientType=0 ); /* IE6-9 */
    border:0px;
    color:white;
    font-family: HelveticaNarrow;
    font-weight: bold;
    font-size: 12pt;
    text-transform: uppercase;
    cursor: pointer;
}
.btn-wide{
    width:728px;
    height:45px;
    background-image: url('images/white-arrow-down.png') no-repeat;
    background-position: 50% 50%;
}

我猜是因为.btn类，导致.btn-wide类中的背景被忽略了。

在这个例子中，什么是最好的标记解决方案？ 🙂

我更新了css。

.btn{
background: rgb(0,166,255); /* Old browsers */
background: -moz-linear-gradient(top,  rgba(0,166,255,1) 0%, rgba(0,166,255,1) 50%, rgba(2,154,236,1) 53%, rgba(2,154,236,1) 100%); /* FF3.6+ */
background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,rgba(0,166,255,1)), color-stop(50%,rgba(0,166,255,1)), color-stop(53%,rgba(2,154,236,1)), color-stop(100%,rgba(2,154,236,1))); /* Chrome,Safari4+ */
background: -webkit-linear-gradient(top,  rgba(0,166,255,1) 0%,rgba(0,166,255,1) 50%,rgba(2,154,236,1) 53%,rgba(2,154,236,1) 100%); /* Chrome10+,Safari5.1+ */
background: -o-linear-gradient(top,  rgba(0,166,255,1) 0%,rgba(0,166,255,1) 50%,rgba(2,154,236,1) 53%,rgba(2,154,236,1) 100%); /* Opera 11.10+ */

filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#00a6ff', endColorstr='#029aec',GradientType=0 ); /* IE6-9 */
border:0px;
color:white;
font-family: HelveticaNarrow;
font-weight: bold;
font-size: 12pt;
text-transform: uppercase;
cursor: pointer;
position:relative;
width:728px;
height:45px;
}
.btn div{
position:absolute;
top:0;
left:0;
right:0;
bottom:0;
background-image: url('https://cdn4.iconfinder.com/data/icons/ionicons/512/icon-ios7-arrow-right-128.png');
background-position: right;
background-repeat:no-repeat;
background-size:32px 32px;
}

根据您的图片更改箭头图片路径。

问题在于您正在使用background简写属性，因此尝试应用第二个背景图像只会覆盖之前的语句（渐变）。
您可以使用逗号分隔的背景图像语句，如下所示。
CSS

.btn{
    background-image: /* note bg image */
        url(http://lorempixel.com/output/abstract-q-c-32-32-2.jpg),
        linear-gradient(to bottom,  rgba(0,166,255,1) 0%,rgba(0,166,255,1) 50%,rgba(2,154,236,1) 53%,rgba(2,154,236,1) 100%); /* W3C */
    background-repeat:no-repeat;
    border:0px;
    color:white;
    font-family: HelveticaNarrow;
    font-weight: bold;
    font-size: 12pt;
    text-transform: uppercase;
    cursor: pointer;
    background-position:50% 50%;
}
.btn-wide{
    width:728px;
    height:45px;
}
