响应式卡片布局 CSS 设计未修复

Question

我想制作响应式但不固定的卡片。我应该对 CSS 进行哪些更改，以便相应地更改它们的大小。

这是Working Fiddle的小提琴链接

汽车应该通过调整窗口大小来改变它的大小，但是按钮的位置应该只在底部，并且不管内容如何，​​所有卡片的大小应该相同。

Answer 1

我相信您需要做的就是将卡的width 更改为min-width。这将强制卡片的宽度为100%，直到230px。正如您在我修改后的 JSFiddle 版本中看到的那样。

您应该记住的是，您的卡片内容被分解为多行内容。每行看起来应该是卡片的 100% 宽度，因此您不需要实际应用内容的宽度，只需提供 display: block。这将迫使它成为其父级的 100% 宽度。内容是其父级的 100% 宽度，它的灵活性将始终取决于父级。因此，您可以将父母的宽度设置为 100%、50%、200px 等等，内容将始终跟随。

如果您需要我澄清任何事情，请告诉我:)
