我的页面文本以不透明图像为中心。在悬停时，文本和不透明度消失，显示清晰的图像。在Chrome和Firefox中，文本以图像为中心，但在Safari中它会偏移。

铬/火狐： chrome

Safari中： safari

font-size: 14px;
text-transform: uppercase;
}

.btn{
letter-spacing: 1px;
}

.btn-default {
border: none;
padding: 10px 15px

}

.btn-default:hover,{

Answer 1

您缺少CSS3属性transform的供应商前缀。在这种情况下，-webkit-transform缺失。

将您的.address定义更改为：

    .address {
        text-align: center;
        font-family: 'Raleway', sans-serif;
        font-size: 40px;
        color: #626262;
        font-weight: 100;
        opacity: 1;
        position: absolute;
        top: 50%;
        left: 50%;
        -moz-transform: translate(-50%,-50%);
        -ms-transform: translate(-50%,-50%);
        -o-transform: translate(-50%,-50%);
        -webkit-transform: translate(-50%,-50%);
        transform: translate(-50%,-50%);
        -moz-transition: opacity 0.5s ease;
        -o-transition: opacity 0.5s ease;
        -webkit-transition: opacity 0.5s ease;
        transition: opacity 0.5s ease;
    }

以Chrome / Firefox为中心的图片上的文字，但不是Safari
