css - 如何使 CSS Grid 调整内容的大小

Question

我想要一个包含 4 个框的列，它们是响应式的并且也位于页面的中心，其余的在代码的注释中解释

我找到了一个解决方案，但它阻止了它位于中心，我将所有内容都包含在我尝试的代码中。

• 这会调整它的大小，但由于某种原因它会阻止它位于中心。

/* THIS RESIZES IT, BUT PREVENTS IT FROM BEING IN THE CENTER FOR SOME REASON */

.wrapper {
  display: grid;
  grid-template-columns: 1fr;
  grid-template-rows: 1fr 1fr 1fr 1fr;
  grid-template-areas: "1" "2" "3" "4";
  position: relative;
  top: 25rem;
  left: 50%;
  transform: translate(-50%, -50%);
}

.wrap {
  min-width: 30rem;
  max-width: 60rem;
  padding: 2rem;
  margin: 1rem;
  border: 3px solid #fff;
  background-color: #c8e6c9;
}

<div class="wrapper">
  <div class="wrap">1</div>
  <div class="wrap">2</div>
  <div class="wrap">3</div>
  <div class="wrap">4</div>
</div>

• 这是完美的，但没有调整它的大小

/*  THIS IS PERFECT, EXCEPT IT DOESN'T RESIZE IT */

.wrapper {
  display: grid;
  grid-template-columns: 1fr;
  grid-template-rows: 1fr 1fr 1fr 1fr;
  grid-template-areas: "1" "2" "3" "4";
  position: fixed;
  top: 50%;
  left: 50%;
  transform: translate(-50%, -50%);
}

.wrap {
  min-width: 30rem;
  max-width: 60rem;
  padding: 2rem;
  margin: 1rem;
  border: 3px solid #fff;
  background-color: #c8e6c9;
}

<div class="wrapper">
  <div class="wrap">1</div>
  <div class="wrap">2</div>
  <div class="wrap">3</div>
  <div class="wrap">4</div>
</div>

非常感谢。

How I would like to have it

Answer 1

您可以使用 html 和 body 通过 flex 将您的内容居中:

body {
  min-height: 100vh;
  display: flex;
  margin: 0;
}

.wrapper {
  margin: auto;
  display: grid;
  grid-template-columns: 1fr;
  grid-template-rows: 1fr 1fr 1fr 1fr;
  grid-template-areas: "1" "2" "3" "4";
}

.wrap {
  min-width: 30rem;
  max-width: 60rem;
  padding: 2rem;
  margin: 1rem;
  border: 3px solid #fff;
  background-color: #c8e6c9;
}

<div class="wrapper">
  <div class="wrap">1</div>
  <div class="wrap">2</div>
  <div class="wrap">3</div>
  <div class="wrap">4</div>
</div>
