Question

我有3个flex项：标题，内容和页脚。我想要一切都要弯曲但是标题恰好是250px ...我添加了一个样式.height-250 {max-height: 250px;}但是它没有用。

/* GRID */
.grid {
  display: flex;
}
.col {
  background-color: rgba(100, 255, 255, 0.1);
  border: 1px solid rgb(100, 255, 225);
  padding: 5px;
}
.col-1-12 {
  flex-basis: 8.3333%;
}
.col-2-12 {
  flex-basis: 16.6666%;
}
.flex-column {
  flex-direction: column;
}
.full-width {
  flex-grow: 100;
}
.wrapper,
html,
body {
  height: 100%;
  margin: 0;
}
.wrapper {
  display: flex;
  flex-direction: column;
}
.height-250 {
  max-height: 250px;
}

<div class="wrapper grid flex-column">
  <div class="col col-1-12 height-250">Header</div>
  <div class="grid col full-width col-2-12">Content</div>
  <div class="col col-1-12">Footer</div>
</div>

Answer 1

您应该使用max-height: 250px而不是flex: 0 0 250px而不是flex-direction: column，而是将元素的高度设置为250px。

.grid {
  display: flex;
}
.col {
  background-color: rgba(100, 255, 255, 0.1);
  border: 1px solid rgb(100, 255, 225);
  padding: 5px;
}
.col-1-12 {
  flex-basis: 8.3333%;
}
.col-2-12 {
  flex-basis: 16.6666%;
}
.flex-column {
  flex-direction: column;
}
.full-width {
  flex-grow: 100;
}
.wrapper,
html,
body {
  height: 100%;
  margin: 0;
}
.wrapper {
  display: flex;
  flex-direction: column;
}
.height-250 {
  flex: 0 0 250px;
}

<div class="wrapper grid flex-column">
  <div class="col col-1-12 height-250">Header</div>
  <div class="grid col full-width col-2-12">Content</div>
  <div class="col col-1-12">Footer</div>
  </div

将特定高度设置为弹性项目
