浮动左和右div:我想让它更有响应性

Question

我有两个div:左边宽，右边边栏。我想让它更有响应性(在较低宽度的屏幕上:左边的面板应该变薄，但是侧边栏应该是相同的宽度，但是它不应该在宽面板下)。如何修正这段代码？

CSS代码：

section {
  padding-right: 2%;
  width: 70%;
  max-width: 700px;
  float: left;
  box-sizing: border-box;
  display: block;
  background-color: red; }

aside {
  max-width: 250px;
  padding-right: 2%;
  width: 36%;
  display: block;
  float: right;
  background-color: yellow;
  box-sizing: border-box; }

Answer 1

尝试：

body {
  margin:0; padding:0;}

section {
  display: block;
  margin:6px 262px 0 6px;
  padding: 6px;
  max-width: 700px;
  box-sizing: border-box;
  background-color: red; }

aside {
  display: block;
  position: absolute;
  top: 0;
  right: 0;
  width: 250px;
  margin: 6px 6px 0 0;
  padding: 6px;
  background-color: yellow;
  box-sizing: border-box;}

我对你的风格做了很多改变。

即：

1) <section>仍然具有最大宽度，但不再具有指定的宽度。相反，在任何小于700px的页面宽度上，其宽度总是自动重新计算为页面宽度的100%减去左右边距。

2) <section>不再具有float:left;属性。其左右边距的宽度决定了其在页面上的位置。

3) <aside>不再具有float:right;属性。相反，它拥有一个position:absolute; of top:0; right:0;和利润率，以抵消该头寸的影响。

4)将动态宽度填充(padding-right: 2%;)替换为固定宽度的6px填充.实际上，margins和paddings在<section>和<aside>中都是固定宽度的6px。
