网站整体布局变灰，如何修改？

只需要在页面加入一段css

<style type="text/css">
	html{ 
		filter: grayscale(100%); 
		-webkit-filter: grayscale(100%); 
		-moz-filter: grayscale(100%); 
		-ms-filter: grayscale(100%); 
		-o-filter: grayscale(100%); 
		filter: url("data:image/svg+xml;utf8,#grayscale"); 
		filter:progid:DXImageTransform.Microsoft.BasicImage(grayscale=1); 
		-webkit-filter: grayscale(1);
	} 
</style>
