在最近工作中，开发过程中需要设定一个图片变为灰色，刚开始我以为是更换图片，可是做了一段时间发现CSS就可以设定图片颜色变回灰色。具体的代码如下：

图片如下：

具体的实现由两种方法：一个是CSS3的滤镜功能。具体代码如下：

<span style="font-size:18px;">.gray {      -webkit-filter: grayscale(100%);     -moz-filter: grayscale(100%);     -ms-filter: grayscale(100%);     -o-filter: grayscale(100%);          filter: grayscale(100%); 	     filter: gray; }</span>

只要把上面代码拷过去，设定成你想修改的图片样式就可以了。例如

<img  src="/static/imghwm/default1.png" data-src="1.jpg" class="lazy" alt="CSS设定图片变灰色_html/css_WEB-ITnose" > <img  class="gray lazy" src="/static/imghwm/default1.png" data-src="1.jpg" alt="CSS设定图片变灰色_html/css_WEB-ITnose" >
