调整窗口大小时CSS浮动div重叠或不向下移动

Question

I need 2 div with one is floated left so when we resize the window into a small window the second div will move downward. 我需要2个div，其中一个向左浮动，因此当我们将窗口调整为小窗口时，第二个div将向下移动。

 body, html { width: 100%; height: 100%; } .container { overflow: hidden; } .container div { width: 500px; height: 500px; border: 1px solid black; }

 <!DOCTYPE html> <html> <head> <title>Home</title> </head> <body> <div class="container"> <div style="float: left"> aaa </div> <div> bbb </div> </div> </body> </html>

this code will make the second div overlap with the first div, if I add display:flex in the container it won't overlap anymore but the div size is resizing with the windows size and the second div won't go downward. 这段代码将使第二个div与第一个div重叠，如果我在容器中添加display：flex，它将不再重叠，但是div的大小将随着窗口大小而调整，并且第二个div不会向下移动。

What is wrong? 怎么了？ I need my div to be exactly 500px. 我需要我的div正好是500px。 Thanks :) 谢谢：）

Answer 1

From what I understand, you want to make the second div go down after resizing the browser. 据我了解，您想在调整浏览器大小后使第二个div变小。 So you can use media queries for that: 因此，您可以为此使用媒体查询：

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

.container {
  overflow: hidden;
}

.container div:first-child {
  float: left;
  width: 500px;
  height: 500px;
  border: 1px solid red;
}

.container div:last-child {
  width: 500px;
  height: 500px;
  border: 1px solid black;
}

@media (max-width: 500px) {
    .container div:last-child {
        clear: both;
    }
}

<!DOCTYPE html>
<html>

<head>
  <title>Home</title>
  <meta name="viewport" content="width=device-width, initial-scale=1">

</head>

<body>
  <div class="container">
    <div>
      aaa
    </div>
    <div>
      bbb
    </div>
  </div>
</body>

</html>

I separated the style of the two divs, and removed the float:left from the inline style. 我分离了两个div的样式，并从内联样式中删除了float:left 。 The <meta> is also important for the media query to work. <meta>对于媒体查询的工作也很重要。 I used clear:both to clear the float of the first div from the second, thus not affecting the second div. 我使用clear:both来清除第二个div的第一个div的浮动，因此不影响第二个div。

I didn't put this in a snippet because the media does not seem to work there, but is working in my computer 我没有将其放在代码段中，因为该媒体似乎在这里不起作用，但是在我的计算机上可以工作

Answer 2

You have to set float in second div also. 您还必须在第二个div中设置float 。 Or in media query you have to set the display: block in both div. 或在媒体查询中，您必须在两个div中都设置display: block 。 check updated snippet below.. 检查下面的更新的片段。

 body, html { width: 100%; height: 100%; } .container { overflow: hidden; } .container div { width: 500px; height: 500px; border: 1px solid black; }

 <!DOCTYPE html> <html> <head> <title>Home</title> </head> <body> <div class="container"> <div style="float: left"> aaa </div> <div style="float: right"> bbb </div> </div> </body> </html>
