通过CSS调整背景图片的大小 [英] Resizing a background image via CSS

问题描述

我有这个背景图片是175x175，但我想做一个CD封面。在下面的代码中（ jsFiddle可用），您会看到它未调整大小，而只是裁剪。如何解决此问题？

I have this background image that is 175x175 but I am trying to make a "CD" cover out of it. In the code below (jsFiddle available), you will see it is not resized but merely "cropped". How do I fix this?

HTML：

<div class="cd"><div class="hole"></div></div>
<p>I want the image above to be resized to 75x75... but it's not</p>

<img src="http://userserve-ak.last.fm/serve/126/23679395.jpg" alt="Test" />
<p>Actual image size above.</p>

CSS：

.cd {
    -moz-border-radius: 63px;
    -webkit-border-radius: 63px;
    border-radius: 63px;
    background-image: url('http://userserve-ak.last.fm/serve/126/23679395.jpg');
    width: 75px;
    height: 75px;
    position: relative;
    border:1px solid #A1A1A1;
}
.cd .hole {
    width: 20px;
    height: 20px;
    position: absolute;
    background-color: #ddd;
    border:1px solid #A1A1A1;
    left: 28px;
    top: 28px;
    -moz-border-radius: 15px;
    -webkit-border-radius: 15px;
    border-radius: 15px;
}

推荐答案

https://developer.mozilla.org/en/CSS/background-size =nofollow noreferrer> background-size CSS属性：

Use the background-size CSS property:

background-size: 75px 75px;

或者：

background-size: 100% 100%;

还有缩写 背景 属性：

There's also the shorthand background property:

background: url('http://userserve-ak.last.fm/serve/126/23679395.jpg') 100% 100%;
