在两个div之间绘制一条静态线

I have three divs on the same line and want to connect them with a line:

我在同一行有三个div,想要用一行连接它们:

Unfortunately, every way I tried collided with the method of display, e.g. inline-block and vertically aligned spacer divs of height 50% with bottom-border.

不幸的是,我试过的每一种方式都与显示方法相冲突,例如内嵌块和垂直对齐的间隔div高度为50%,带有底边。

if it stands on 1 line, you could add pseudo element and filter first and last box, to draw or not a line aside.

如果它站在1行,你可以添加伪元素并过滤第一个和最后一个框,以绘制或不绘制一条线。

div.boxItem { 
  display: inline-block;
  border: 1px solid black;
  padding: 1em;  
  margin-right: 5em;
  position:relative
}

.boxItem:before,
.boxItem:after
{
  content:'';
  width:5em;/* size of your margin */
  border-bottom:1px solid;
  position:absolute;
  top:50%;

}
:after {
  left:100%;
}
:before {
  right:100%;
}
.boxItem:first-of-type:before,
.boxItem:last-of-type:after {
  display:none;
}
.myBox {
  white-space:nowrap; 
/* */ text-align:center;
  }
body {

}

<div class="myBox">
  <div class="boxItem">1</div>
  <div class="boxItem">2</div>
  <div class="boxItem">3</div>
  <div class="boxItem">4</div>
</div>
<div class="myBox">
  <div class="boxItem">1</div>
  <div class="boxItem">2</div>
  <div class="boxItem">3</div>
</div>
<div class="myBox">
  <div class="boxItem">1</div>
  <div class="boxItem">2</div>
</div>
<div class="myBox">
  <div class="boxItem">1</div>
</div>

Try this:

div.boxItem { 
  display: inline-block;
  border: 1px solid black;
  padding: 1em;
}

div.line {
  display: inline-block;
  border-top: 1px solid black;
  width: 2em;
}

<div class="boxItem">1</div><!--
--><div class="line"></div><!--
--><div class="boxItem">2</div><!--
--><div class="line"></div><!--
--><div class="boxItem">3</div>

Note: I used  to comment out the white space ensuring the line actually touches the divs. More info on that bit: https://*.com/a/19038859/2037924

注意:我使用注释掉空白区域,确保线条实际触及div。有关该位的更多信息:https://*.com/a/19038859/2037924

You could add a div with the width of your margin:

您可以添加一个带有边距宽度的div:

<div class="boxItem">1</div>
<div class="emptyDiv"></div>
<div class="boxItem">2</div>
<div class="emptyDiv"></div>
<div class="boxItem">3</div>

CSS:

div {
  display: inline-block;
}

div.emptyDiv{
 border: 1px solid black;
 width:25em;
}

div.boxItem { 
  border: 1px solid black;
  padding: 1em;
}
