使用flexbox将元素对齐到底部

Question

我正在尝试使用align-content: flex-end（并尝试align-self: flex-end）使用Flexbox将DIV与底部对齐，但没有运气。

我在这里做错了什么？我认为align-content已经对齐......以及允许的高度/宽度的内容。

＆＃13;

＆＃13;

html, body {
  height: 100%;
}

div.slots {
  background: white;
  display: flex;
  flex-direction: column;
  width: 250px;
  align-content: flex-end;
}
div.slots div.top_slots {
  display: grid;
  grid-template-columns: 25% 50% 25%;
}
div.slots div.bottom_slots {
  display: grid;
  grid-template-columns: 25% 25% 25% 25%;
}
div.slots div.slot {
  display: flex;
  align-items: center;
  justify-content: center;
  cursor: pointer;
  background: #676767;
  height: 35px;
}
div.slots div.slot svg {
  fill: #272727;
}
div.slots div.slot:hover {
  background-color: #8d8d8d;
}
div.slots div.pane {
  background: grey;
  height: 100px;
  width: auto;
  text-align: center;
}

Answer 1

目前，.slots是包含弹性项目的弹性容器。使用flexbox将其与底部对齐的一种方法是将其放在另一个flexbox容器中。这可以通过询问问题来显示：＆＃34;将其与底部对齐？＆＃34;答案是：＆＃34;到另一个弹性容器的底部＆＃34;。

因此，除了作为flex 容器之外，.slots也可以是另一个Flex容器中的flex 项。然后，您可以将.slots与其容器的底部对齐。

下面，我已将其容器<body>设置为.slots元素的灵活容器。这类似于"sticky footer", detailed at CSS-Tricks的方法之一。

Michael_B's Scenario #2可能是一种更有效的解决方案（更少的容器）。它将所有弹性项目放在.slots的底部，通过height:100vh扩展页面的整个高度。

我说这个决定部分取决于网页上还有什么。

Answer 2

场景1

align-content属性以及align-items和align-self仅适用于Flex容器的交叉轴。

在flex-direction: column的容器中，主轴是垂直的，横轴是水平的。这意味着align-*属性会向左/向右移动项目，而不是向上/向下移动。

因此align-content不会在列方向容器中对齐Flex项目。

要考虑的下一个问题是Flex项目及其内容不是一个元素。它们代表两个要素。因此，要对齐Flex项的内容，请使用嵌套的Flex容器。

如果目标是将整个元素对齐到底部，则使用justify-content: flex-end（主轴），而不是align-content: flex-end（仅限横轴和多线容器）。

Answer 3

对齐内容将项目与横轴对齐。通常是垂直的，因此＆＃34;身高＆＃34;。

但是如果使用flex-direction：列轴开关，那么主轴是垂直的，横轴是水平的。

因此，您可以使用justify-content调整flex项目上flex项目的垂直对齐方式：column flex-container。

Answer 4

将flex-grow: 1添加到中间元素并删除其height: 100px以允许它变高，并将margin-top: auto添加到底部元素以将其移至底部：

html, body {
  height: 100%;
}

div.slots {
  background: white;
  display: flex;
  flex-direction: column;
  width: 250px;
  height: 100vh;
}
div.slots div.top_slots {
  display: grid;
  grid-template-columns: 25% 50% 25%;
}
div.slots div.bottom_slots {
  display: grid;
  grid-template-columns: 25% 25% 25% 25%;
  margin-top: auto;
}
div.slots div.slot {
  display: flex;
  align-items: center;
  justify-content: center;
  cursor: pointer;
  background: #676767;
  height: 35px;
}
div.slots div.slot svg {
  fill: #272727;
}
div.slots div.slot:hover {
  background-color: #8d8d8d;
}
div.slots div.pane {
  background: grey;

  text-align: center;
  flex-grow: 1;
