我使用mobile-first方法创建了一个响应式四列布局。最小的屏幕显示1列,较大的屏幕显示2列,最大的屏幕显示4列。
到目前为止,它似乎是有效的,但我想让你看看我的代码,告诉我我的方法是否有什么问题。我很感激你的意见。

最佳答案

如果你想从css中删除calc,你可以这样做。

<!DOCTYPE html>
<html lang="en-US">
<head>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>FlexBox Test</title>
  <style>
  :root {
    box-sizing: border-box;
  }

  *, *::before, *::after {
    box-sizing: inherit;
  }

  /* mobile phone */
  .flex-container {
    display: flex;
    flex-wrap: wrap;
    max-width: 1400px;
    margin: 0 auto;
    border: 1px solid red;
    padding: 1em;
  }

  .flex-item-1 {
    background: indianred;
  }

  .flex-item-2 {
    background: blue;
  }

  .flex-item-3 {
    background: tomato;
  }

  .flex-item-4 {
    background: coral;
  }

  .flex-item {
    flex: 100%;
    height: 100px;
  }

  /* tablet */
  @media screen and (min-width: 675px) and (max-width: 960px) {
    .flex-item {
      flex: 1 0 19em;
    }

    .flex-item:nth-child(2n) {
	  margin-left: 1em;
    }
  }

  /* desktop */
  @media screen and (min-width: 960px) {
    .flex-item {
	  flex: 1 0;
    }

    .flex-container > * + * {
      margin-left: 1em;
    }
  }
  </style>
</head>
<body>
  <div class="flex-container">
    <div class="flex-item flex-item-1">
      1
    </div>

    <div class="flex-item flex-item-2">
      2
    </div>

    <div class="flex-item flex-item-3">
      3
    </div>

    <div class="flex-item flex-item-4">
      4
    </div>
  </div>
</body>
</html>

不过,要保持初始示例中的边距,我必须更改tablet屏幕的@media screen and (min-width: 675px) and (max-width: 960px)。如果不是,则在第一行显示特定浏览器宽度的三个块(与您所需的行为不同)。
你觉得怎么样?
