初学CSS，在写logo图片背景加链接的时候发现下面2种代码都可以实现，哪种更合适一些呢？

第一个是这样写：

logo {
float: left;
width: 160px;
height: 50px;
background-image: url(./images/[email protected]);
background-image: -webkit-image-set(
url(./images/[email protected]) 1x,
url(./images/[email protected]) 2x);
}

logo a {
display: block;
width: 160px;
height: 50px;
text-indent: -9999em;
}

第二个是这样写：

logo {
float: left;
}

logo a {
display: block;
width: 160px;
height: 50px;
background-image: url(./images/[email protected]);
background-image: -webkit-image-set(
url(./images/[email protected]) 1x,
url(./images/[email protected]) 2x);
text-indent: -9999em;
}

谢谢，请指教。

images/[email protected]

50px

第二个简洁，没有重复的，float 和 display:block 不需要同时设
