明确地说，我不想删除内联块元素之间的空间 - 我想添加它。
我想要的是有一个菜单项网格，一行可以有 2、3 或 4 个项目，我想使用媒体查询来实现。
如何在我的 li 项目之间添加空间，但每行的左侧和右侧也没有边距？（填充不会解决这个问题。）我可以只使用 CSS 来实现吗？
* {
-webkit-box-sizing: border-box;
-moz-box-sizing: border-box;
box-sizing: border-box;
border: solid 1px;
font-size: 0;
}
#main {
max-width: 450px;
margin: 0 auto;
}
.item {
display: inline-block;
width: 200px;
}
.item img {
width: 200px;
}
.clearfix {
overflow: auto;
}
li {
list-style-type: none;
}<div id="main">
