如何使旁边的列随着平行列中内容的大小而增长

Question

你好，我怎样才能使侧边菜单随着并行容器的内容而增长，它也应该随着它的内容而扩展。

我试图确保包含在 aside 标记中的左侧栏与包含在 div 栏 .right_panel 中的右侧内容的大小相同。根据 Whosebug 上的类似查询，我能够通过将 html 和 body 标记的大小以及 .wrapper class 设置为 height: 100% 来完成此操作。

但是现在当我向 main 添加更多内容时 .wrapper 没有展开。我试图将 height 更改为 min-height，但它会将旁边的内容缩小到其内容大小。

我知道我可以使用 flex 布局来完成此操作，但因为 flex 超出了我的课程范围，还因为我想学习替代方法，以防将来我需要使用它们来与旧浏览器兼容我正在寻找不使用 flex 布局的解决方案。

下面的代码段和 JSFiddle link：

html,
body {
    height: 100%;
}

body {
    font-family: Arial, Helvetica, sans-serif;
    font-size: 16px;
    background-color: blue;
}

h1,
h2,
h3,
h4,
h5,
h6 {
    font-family: 'Franklin Gothic Medium', 'Arial Narrow', Arial, sans-serif;
}

.wrapper {
    margin: 10px auto 30px;
    padding: 0;
    width: 80%;
    background-color: white;
    height: calc(100% - 40px);
    max-height: 100%;
}

aside.left_panel {
    float: left;
    min-height: 100%;
    width: 130px;
    background-color: #9eb9f1;
    padding-left: 30px;
    overflow: auto;
}

.right_panel {
    margin-left: 160px;
}

nav ul {
    list-style-type: none;
    padding: 0;
}

header {
    background-color: #6f90d1;
    padding: 20px;
}

header h1 {

    font-size: 60px;
    color: darkblue;
}

main {
    padding: 20px 20px 0;
}

main h2 {
    color: #6f90d1;
}

main #lantern {
    height: 400px;
    width: 200px;
}

main img {
    margin: 10px;
}

main h2{
    margin-bottom: 30px;
}
main p {
    margin-bottom: 30px;
}

footer {
    text-align: center;
    margin: 10px 0;
}

.f-right {
    float: right;
    overflow: auto;
}

.f-left {
    float: left;
    overflow: auto;
}

Answer 1

使用Table布局

一个解决方案是使用 table 布局 在 wrapper 上使用 display: table 并使 left-section 和 right-section 变成 table-cell - 请看下面的演示：

html,body {
  height: 100%;
}
body {
  font-family: Arial, Helvetica, sans-serif;
  font-size: 16px;
  background-color: blue;
}
h1,h2,h3,h4,h5,h6 {
  font-family: 'Franklin Gothic Medium', 'Arial Narrow', Arial, sans-serif;
}
.wrapper {
  margin: 10px auto 30px;
  padding: 0;
  width: 80%;
  background-color: white;
  height: calc(100% - 40px);
  max-height: 100%;
  display: table; /* added */
}
aside.left_panel {
  /* float: left; */
  min-height: 100%;
  width: 130px;
  background-color: #9eb9f1;
  padding-left: 30px;
  overflow: auto;
  display: table-cell; /* added */
  vertical-align: top; /* added */
}
.right_panel {
  /*margin-left: 160px;*/
  display: table-cell; /* added */
}
nav ul {
  list-style-type: none;
  padding: 0;
}
header {
  background-color: #6f90d1;
  padding: 20px;
}
header h1 {
  font-size: 60px;
  color: darkblue;
}
main {
  padding: 20px 20px 0;
}
main h2 {
  color: #6f90d1;
}
main #lantern {
  height: 400px;
  width: 200px;
}
main img {
  margin: 10px;
}
main h2 {
  margin-bottom: 30px;
}
main p {
  margin-bottom: 30px;
}
footer {
  text-align: center;
  margin: 10px 0;
}
.f-right {
  float: right;
  overflow: auto;
}
.f-left {
  float: left;
  overflow: auto;
}

<div class="wrapper">
  <aside class="left_panel">
    <nav>
      <ul>
        <li>Home</li>
        <li>Manu item 1</li>
        <li>Manu item 2</li>
        <li>Manu item 3</li>
      </ul>
    </nav>
  </aside>
  <div class="right_panel">
    <header>
      <h1>Name of the website</h1>
    </header>
    <main>
      <img id="lantern" class="f-right" src="https://upload.wikimedia.org/wikipedia/commons/thumb/e/e0/PlaceholderLC.png/600px-PlaceholderLC.png" alt="">
      <h2>Subheading 1</h2>

使用浮点数

您可以尝试这个 - 但您没有得到正确的溢出或者将无法使列的高度相同 - 请参见示例 fiddle 那个：

html,body {
  height: 100%;
}
body {
  font-family: Arial, Helvetica, sans-serif;
  font-size: 16px;
  background-color: blue;
}
h1,h2,h3,h4,h5,h6 {
  font-family: 'Franklin Gothic Medium', 'Arial Narrow', Arial, sans-serif;
}
.wrapper {
  margin: 10px auto 30px;
  padding: 0;
  width: 80%;
  background-color: white;
  height: calc(100% - 40px);
  max-height: 100%;
  overflow: hidden; /* to clear the float */
}
aside.left_panel {
  float: left;
  min-height: 100%;
  width: 130px;
  background-color: #9eb9f1;
  padding-left: 30px;
  overflow-y: auto; /*changed to overflow-y */
}
.right_panel {
  float: left; /* added */
  width: calc(100% - 160px); /* added */
  /*margin-left: 160px;*/
}
nav ul {
  list-style-type: none;
  padding: 0;
}
header {
  background-color: #6f90d1;
  padding: 20px;
}
header h1 {
  font-size: 60px;
  color: darkblue;
}
main {
  padding: 20px 20px 0;
}
main h2 {
  color: #6f90d1;
}
main #lantern {
  height: 400px;
  width: 200px;
}
main img {
  margin: 10px;
}
main h2 {
  margin-bottom: 30px;
}
main p {
  margin-bottom: 30px;
}
footer {
  text-align: center;
  margin: 10px 0;
}
.f-right {
  float: right;
  overflow: auto;
}
.f-left {
  float: left;
  overflow: auto;
}

<div class="wrapper">
  <aside class="left_panel">

      <ul>
        <li>Home</li>
        <li>Manu item 1</li>
        <li>Manu item 2</li>
        <li>Manu item 3</li>
      </ul>
    </nav>
  </aside>
  <div class="right_panel">

      <h1>Name of the website</h1>
    </header>
    <main>
      <img id="lantern" class="f-right" src="https://upload.wikimedia.org/wikipedia/commons/thumb/e/e0/PlaceholderLC.png/600px-PlaceholderLC.png" alt="">
      <h2>Subheading 1</h2>

但是有一个 hack - 使用 large margin & padding。请注意，您需要删除 wrapper 上设置的 height 和 max-height - 请参阅下面的演示：

html,body {
  height: 100%;
}
body {
  font-family: Arial, Helvetica, sans-serif;
  font-size: 16px;
  background-color: blue;
}
h1,h2,h3,h4,h5,h6 {
  font-family: 'Franklin Gothic Medium', 'Arial Narrow', Arial, sans-serif;
}
.wrapper {
  margin: 10px auto 30px;
  padding: 0;
  width: 80%;
  background-color: white;
  /*height: calc(100% - 40px);
  max-height: 100%;*/
  overflow: hidden; /* to clear the float */
}
aside.left_panel {
  float: left;
  min-height: 100%;
  width: 130px;
  background-color: #9eb9f1;
  padding-left: 30px;
  overflow-y: auto; /*changed to overflow-y */
  margin-bottom: -100000px; /* a large value */
  padding-bottom: 100000px; /* a large value */
}
.right_panel {
  float: left; /* added */
  width: calc(100% - 160px); /* added */
  /*margin-left: 160px;*/
  margin-bottom: -100000px; /* a large value */
  padding-bottom: 100000px; /* a large value */
}
nav ul {
  list-style-type: none;
  padding: 0;
}
header {
  background-color: #6f90d1;
  padding: 20px;
}
header h1 {
  font-size: 60px;
  color: darkblue;
}
main {
  padding: 20px 20px 0;
}
main h2 {
  color: #6f90d1;
}
main #lantern {
  height: 400px;
  width: 200px;
}
main img {
  margin: 10px;
}
main h2 {
  margin-bottom: 30px;
}
main p {
  margin-bottom: 30px;
}
footer {
  text-align: center;
  margin: 10px 0;
}
.f-right {
  float: right;
  overflow: auto;
}
.f-left {
  float: left;
  overflow: auto;
}

使用 flexboxes

最后但并非最不重要的；因为 flexboxes 有 IE11+ 并且在所有现代浏览器中都支持，所以我更喜欢它 - 感谢你让我也复习了我的知识。 :)

html,body {
  height: 100%;
}

}
.wrapper {
  margin: 10px auto 30px;
  padding: 0;
  width: 80%;
  background-color: white;
  /*height: calc(100% - 40px);*/
  /*max-height: 100%;*/
  display: flex; /* added */
}
aside.left_panel {
  /* float: left; */
  min-height: 100%;
  width: 130px;
  background-color: #9eb9f1;
  padding-left: 30px;
  overflow-y: auto; /* changed to overflow-y*/
}
.right_panel {
  /*margin-left: 160px;*/
}
nav ul {
  list-style-type: none;
  padding: 0;
}
header {
  background-color: #6f90d1;

Answer 2

您可以删除浮动并将包装器设置为 display: flex。同时删除 wrapper 的高度属性和右列的 margin-left。
