使用minmax（）函数

标签： html css grid css-grid

我正在尝试创建一个响应式页面，其中包含＆＃34;框＆＃34;当浏览器窗口变小时，换行到另一行。我用过：

grid-template-columns: repeat(auto-fit, minmax(200px, 1fr));

在下面的笔中完成此操作。 请参阅链接，例如所需行为。

注意当窗口变小时图标/文本将如何包裹到下面的行，直到有一个网格项位于另一个上面。

但是，在以下链接中创建的整页上有一些禁止此行为的内容;我无法找到禁止此行为的内容。

在上面的链接中，当窗口变小时，最后的div会包含在下面，但是当窗口进一步最小化时，其他网格项仍保留在同一行上。

我稍微使用了代码，并注意到当我为包装类注释掉以下样式时，网格项的行为符合要求。 

.wrapper {
  display: grid;
  grid-gap: 20px;

有人可以告诉我，封装类的网格显示禁止下面的网格项目正确包装吗？

1 个答案:

答案 0 :(得分：0)

由于主.boxes块中的其他更广泛的兄弟块，您的.wrapper网格不会进一步包裹。

默认情况下，当您为块添加display: grid时，它将成为网格容器。您的.wrapper网格容器只有一列，此列的最小宽度由最小大小的子项定义。您的案例中最大的孩子是.main-nav ul，因为它有4列，无论分辨率如何都不会缩小。下一个大容器是.top-container，它也有大量不可收缩的内容。

因此，要解决您的问题，只需使.main-nav ul和.top-container块以任何方式缩小。

另请注意，对于1D布局，您可以使用Flexbox。
