Question

我只需要使用CSS的复选框帮助。

首先它正常运作。但是，我想在单击按钮时将选中的图像叠加在未检查的图像上。怎么做到这一点？

.gchoice_1_1_3 {border: 1px solid red;}

.gchoice_1_1_3 input[type="checkbox"] {display: none; }

.gchoice_1_1_3 input[type="checkbox"] + label:before {
	background: url('http://www.uswebcompany.com/plugins/gravityforms/wp-content/uploads/2016/01/christmasLights.png') 0 0px no-repeat;
    z-index: 10;
	content: "";
	display: inline-block;
	font-size: 12px;
	height: 75px;
	width: 75px;
	line-height: 16px;
	margin: -2px 6px 0 0;
	text-align: center;
	vertical-align: middle;
	positionL relative;
	border-radius: 10px;
	background-color: #6283B2;

.gchoice_1_1_3 input[type="checkbox"]:checked + label:before {

您可以使用多个背景但请务必检查浏览器支持以及应用背景的顺序问题。
