请参阅以下codepen了解我目前拥有的内容:https://codepen.io/anon/pen/GjWYPO
<div class="container">

<div class="col-1-3" style="font-size:0px;">
<div class="col-1-3 bg-green">green 1</div>
<div class="col-1-3 bg-green">green 2</div>

我的问题是,看看codepen,我如何在绿色细胞之间创建一个排水沟。我的研究指出使用负边距和填充,但我不能让它工作。 类似于此处描述的内容:http://www.helloerik.com/the-subtle-magic-behind-why-the-bootstrap-3-grid-works
我的要求是,而不是!创造更多的div。我不想创建一个&#34;行包装器&#34;如果它可以解决当前笔中的html,我真的很高兴。我不介意,并猜测它的一部分解决方案,创建一个&#34;行类&#34;并将其应用于父细胞(此处带有id&#39; batman&#39;),保持绿色细胞。
第二个要求是,即使codepen示例使用3个单元格,该解决方案也适用于任意数量的单元格。所以它不能使用nth-child
第三,我真的不喜欢!使用flex来解决这个问题。
忽略容器类和font-size:0的东西,它只是在使用内联块时删除空格的临时修复。我真正的代码使用php缩小。
我希望这是有道理的。下面是我希望结果如何的图片:
感谢任何帮助, 提前谢谢!

增加了不使用flex的要求。

我认为将此添加到您的CSS中,将为您完成这项工作。
.col-1-3.bg-green{
width:calc(100%/(3/1) - (3-1)*2px);
margin:0px 2px;
}
答案 1 :(得分:1)
您可以选择第二个div并重置宽度和边距:
.col-1-3:nth-child(2) {
margin:0 1em;
width:calc(100% / (3/1) - 2em);
}
.container {
font-size: 0;
}
[class|="col"] {
display: inline-block;
vertical-align: top;
position: relative;
font-size: 20px;
}
.col-1-3 {
width: calc(100% / (3/1));
}
/* here update to overwrite width and add margins rules */
.col-1-3:nth-child(2) {
margin: 0 1em;/* whatever , double it before taking it off from width */
width: calc(100% / (3/1) - 2em);
}
/* end update */
.col-2-3 {
width: calc(100%/(3/2));
}
.col-1 {
width: 100%;
}
.bg-blue {
background-color: #42a5f5;
color: #ffffff;
}
.bg-green {
background-color: #66bb6a;
color: #ffffff;
}
<div class="container">
<div class="col-1-3 bg-blue">blue left</div>
<div class="col-1-3" style="font-size:0px;">
<div class="col-1-3 bg-green">green 1</div>
<div class="col-1-3 bg-green">green 2</div>
<div class="col-1-3 bg-green">green 3</div>
</div>
<div class="col-1-3 bg-blue">blue right</div>
</div>
您可能还想看一下display:flex:
.container{
display:flex;
}
[class|="col"] {
flex:1;/* flex children, spray them evenly */
font-size:20px;
}
.container .container .col-1-3:nth-child(2) {/* select second containere on second level */
margin:0 1em;
}
.bg-blue{
background-color:#42a5f5;
color:#ffffff;
}
.bg-green{
background-color:#66bb6a;
color:#ffffff;
}
<div class="container">
<div class="col-1-3 bg-blue">blue left</div>
<div class="col-1-3 container"><!-- here make it a flex container too -->
<div class="col-1-3 bg-green">green 1</div>
<div class="col-1-3 bg-green">green 2</div>
<div class="col-1-3 bg-green">green 3</div>
</div>
<div class="col-1-3 bg-blue">blue right</div>
</div>
要使用https://codepen.io/anon/pen/xEqQVg
的Codepen第三个选项,float + display:table,bg通过faux column绘制。 这意味着将左右列放在中间容器的前面。
.container{
background-color:#42a5f5;
margin:1em 0;
text-align:center;
font-size:20px;
line-height:30px;
text-shadow:0 0 1px gray;
}
.bg-blue {
width:33%;/* whatever how many of those ? */
background-color:#42a5f5;
color:#ffffff;
}
.float-l {
float:left;
margin-right:-15px;/* cause of border-spacing */
}
.float-r {
float:right;
margin-left:-15px;/* cause of border-spacing */
}
.child-container {
display:table;
table-layout:fixed;/* suppose to spray cells evenly where no width is set to cells */
background:linear-gradient(to left,#42a5f5 15px, transparent 15px),linear-gradient(to right,#42a5f5 15px, transparent 15px) white;/* reproduce blue bg part on white for both sides */
width:calc(34% + 30px);
margin:auto;
border-spacing:15px 0;
}
.bg-green{
display:table-cell;
background-color:#66bb6a;
color:#ffffff;
}
<div class="container">
<div class="float-l bg-blue">blue left</div>

答案 2 :(得分:1)
你可以将它添加到CSS中,它应该可以工作(测试):
.bg-green {
width: calc((100% - ((3 - 1)*2%))/(3/1));
margin-right: 2%;
}
.bg-green:last-child{
margin-right: 0;
}
已编辑的代码段:
.container{
font-size: 0;
}
[class|="col"] {
display:inline-block;
vertical-align: top;
position:relative;
font-size:20px;
}
.col-1-3{
width:calc(100%/(3/1));
}
.col-2-3{
width:calc(100%/(3/2));
}
.col-1{
width:100%;
}
.bg-blue{
background-color:#42a5f5;
color:#ffffff;
}
.bg-green{
background-color:#66bb6a;
color:#ffffff;
}
.bg-green {
width: calc((100% - ((3 - 1)*2%))/(3/1));
margin-right: 2%;
}
.bg-green:last-child{
margin-right: 0;
}
&#13;
<div class="container">
<div class="col-1-3 bg-blue">blue left</div>
<div class="col-1-3" style="font-size:0px;">
<div class="col-1-3 bg-green">green 1</div>
<div class="col-1-3 bg-green">green 2</div>
<div class="col-1-3 bg-green">green 3</div>
</div>
<div class="col-1-3 bg-blue">blue right</div>
</div>
&#13;
只需更换&#34; 3&#34;无论您拥有多少列,都可以根据需要更改边距值。
带有负边距的版本
稍微改变标记(与Bootstrap类似的结构):
<div class="col-1-3">
<div class="bg-green">green 1</div>
</div>
<div class="col-1-3">
<div class="bg-green">green 2</div>
</div>
<div class="col-1-3">
<div class="bg-green">green 3</div>
</div>
以及CSS中的部分
.children-has-gutters > div {
padding-left: 15px;
padding-right: 15px;
box-sizing: border-box;
}
.bg-blue {
background-color:#42a5f5;
color:#ffffff;
width:calc((100%/(3/1)) + 15px);
}
.container{
font-size: 0;
}
[class|="col"] {
display:inline-block;
vertical-align: top;
position:relative;
font-size:20px;
}
.col-1-3{
width:calc(100%/(3/1));
}
.col-2-3{

}
.children-has-gutters{
margin-left:-15px;
margin-right:-15px;
width: calc((100% / (3/1)) + 30px);
}
.children-has-gutters > div{
padding-left:15px;
padding-right:15px;
box-sizing: border-box;
}
.bg-blue{
background-color:#42a5f5;
color:#ffffff;
}
.bg-green{
background-color:#66bb6a;
color:#ffffff;
}

<div class="col-1-3 children-has-gutters" style="font-size:0px;">

请注意,您必须为每个蓝色列添加15px,以避免容器宽度出现问题。你可以玩游戏并检查没有它会发生什么 - 容器中元素的宽度将是100% - 30px(负边距)。

这样的东西? 这是使用flexbox布局。如果你想要更多的浏览器兼容性,那么我认为一个好的选择就是使用任何css框架。
