我正在做一个项目，我到了我应该将块之间的间隙减小到3px的部分。最近2天我已经尽力了，但是我无法获得想要的显示。
这是完成操作的屏幕截图：

最佳答案
我真的相信您不能在这里发布您的代码。甚至我也无法在jsfiddle上克隆它！但是规则就是规则！
无论如何，您可以通过以下方式解决问题：
.ca-item-main {
position: absolute;
width: 405px;
top: 5px;
left: 5px;
right: 5px;
bottom: 5px;
background: #fff;
overflow: hidden;
-moz-box-shadow: 1px 1px 2px rgba(0,0,0,0.2);
-webkit-box-shadow: 1px 1px 2px rgba(0,0,0,0.2);
box-shadow: 1px 1px 2px rgba(0,0,0,0.2);
}
.wrapper {
display: inline-block;
position: relative;
width: 100%;
}
.wrapper img {
display: block;
min-width: 100%;
}
.ca-container {
position: relative;
margin: 25px auto 20px auto;
width: 1230px;
height: 650px;
}
