元素不会完全出现在顶部

Question

我有问题，当添加大量数据时，元素隐藏在屏幕中，请查看下面的图像。

你可以专注于顶部你会注意到没有完全出现的元素。

.container {
  width: 100%;
  height: 100vh;
  display: flex;
  flex-direction: column;
  justify-content: center;
  align-items: center;
}

.container div:first-of-type {
  width: 100%;
  height: 100vh;
  position: fixed;
  background-color: #f4f4f4;
}

.container .card {
  width: fit-content;
  height: auto;
  display: table;
  background-color: #00bce9;
  border-radius: 10px;
  box-shadow: 5px 5px 10px #e6e6e7;
}

.container .card h1:first-of-type {
  width: auto;
  height: fit-content;
  margin: 5px 25px 10px 25px;
  text-align: right;
  color: #606060;
}

.container .card table {
  width: 100%;
  height: 100%;
}

.container .card table tr {
  width: 100%;
  height: 100%;
}

.container .card table tr td {
  padding: 25px;
  color: #606060;
  font-size: 1em;
  cursor: pointer;
}

.container h3:first-of-type {
  width: fit-content;
  height: auto;
  padding: 10px;
  background-color: #b8e986;
  border-radius: 0 0 10px 10px;
  box-shadow: 5px 5px 10px #e6e6e7;
  color: #606060;
  cursor: pointer;
}

在发布之前我发现这个Issue when centering vertically with flexbox when heights are unknown 但它不能和我合作从来没有我会很高兴如果你帮助我因为我在2天前搜索过

Answer 1

尝试：

 .container {
   width: 100%;
  /* removed height */
   display: flex;
   flex-direction: column;
   justify-content: center;
   align-items: center
}

此外，看起来你有一个额外的</tr>高于你的结束</table>
