html - 如何在未指定高度的情况下保持 SVG 线与父 div 相同的高度？

问题描述

所以我试图在两列之间放置一条 SVG 线，但该线没有占用父容器的高度。父容器没有指定高度，因为我希望它自动缩放到最高列。

示例： https ://jsfiddle.net/Lye0z5wx/4/

代码

html,
body {
  width: 100%;
  height: 100%;
}

div.container {
  margin: 40px auto;
  width: 70%;
  display: flex;
  align-items: center;
}

.column {
  display: inline-block;
  width: 40%;
}

svg {
  display: block;
  height: 100%;
  width: 20%;
}
<body>
  <div class="container">
    <div class="column">
      <h3>Content</h3>
      <p>Easily change/switch/swap every placeholder inside every image on Sedna with the included Sketch files. You’ll have this template customised to suit your business in no time!</p>
      <p>Nam vehicula malesuada lectus, interdum fringilla nibh. Duis aliquam vitae metus a pharetra. Lorem ipsum dolor sit amet, consectetur adipiscing elit. Donec fermentum augue quis augue ornare, eget faucibus felis pharetra. Proin condimentum et leo
        quis fringilla.</p>
    </div>
    <svg viewbox="0 0 100 100" preserveAspectRatio="none">
      <line x1="50%" x2="50%" y1="0" y2="100%" style="stroke:rgb(235,235,235);stroke-width:1" />
      Sorry, your browser does not support inline SVG.
    </svg>
    <div class="column">

我一直在尝试几件事来完成这项工作，但 SVG 线在调整浏览器大小时会不断缩小。当我希望它包含父 div 的完整高度时。

谢谢您的帮助！

解决方案

您可以使用填充黑客：

.svgDiv在这种情况下，您将 svg 包装在容器上。拥有.svgDiv并使其与容器一样高height:0。padding-top:100%然后你可以给你的 svg 容器的宽度和高度。

html, body {
  width: 100%;
  height: 100%;
}
div.container {
  margin: 40px auto;
  width: 70%;
  display: flex;
  align-items: center;
  outline:1px solid;
}

.column {
  display: inline-block;
  width: 40%;

}

.column h3{
  color: #1c3653;
  font-size: 20px;
  margin: 0px;
}

.column p {
  color: #1c3653;
  font-size: 15px;
}

svg {
    display: block;
    position: absolute;
    top: 0;
    left: 0;
    width: 100%;
    height: 100%;
}

.svgDiv{ 
   width: 10%;
   height:0;
   padding-top:100%;
   position: relative;
}
  
<div class="container">
		<div class="column">

    <div class="svgDiv">

    </svg>
    </div>

另一种方法是

  • .svgDiv在这种情况下，您将 svg 包装在容器上

  • 您更改align-items: center;为 align-items: stretch;容器

  • 要将文本保持在您align-self:center;为列添加的中心。

  • 接下来你给你的 SVG 的宽度和高度.svgDiv（100%）

html, body {
  width: 100%;
  height: 100%;
}
div.container {
  margin: 40px auto;
  width: 70%;
  display: flex;
  align-items: stretch;
  outline:1px solid;
}

.column {
  display: inline-block;
  width: 40%;
  align-self:center;
}

.column h3{
  color: #1c3653;
  font-size: 20px;
  margin: 0px;
}

.column p {
  color: #1c3653;
  font-size: 15px;
}

svg {
display: block;
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;

}

.svgDiv{ 
width: 10%;
position:relative;
}
<div class="container">
		<div class="column">

我希望这有帮助。
