两列布局，右列有3行

Question

我正在学习css网格，但我发现网格-模板-区域，列和行很难理解。我试图设计聊天屏幕布局，其中将有两列。左列将有对话列表，右列将有三行。一个作为聊天标题，它将被修复，另一行将用于消息列表，第三行将是发送消息的表单，该表单也将被修复。我试着按以下方式做，但它没有像预期的那样起作用

​

.chat-container {
  display: grid;
  grid-template-areas: "chat-list chat-title chat-title" "chat-list message-list message-list" "chat-list chat-form chat-form";
  grid-template-columns: 200px 1fr;
  border-radius: 10px;
  height: 95vh;
  width: 100%;
}

.chat-title {
  padding: 10px;
  background: blue;
}

.chat-list {
  padding: 10px;
  background: red;
}

.message-list {
  padding: 10px;
  background: green;
}

.chat-form {
  padding: 10px;
  background: yellow;
}

<div class="chat-container">
  <section class="chat-list">
    Chat List
  </section>
  <section class="chat-title">Chat title</section>
  <section class="message-list">
    Message List
  </section>
  <section class="chat-form">Chat form</section>
</div>

我已经三次提到聊天列表的每一行，但我仍然没有看到聊天列表块与聊天形式。如何在右列有3行的情况下布局2列？

Answer 1

您需要将这些区域分配给类：

​

.chat-container {
  display: grid;
  grid-template-areas: "chat-list chat-title chat-title" "chat-list message-list message-list" "chat-list chat-form chat-form";
  grid-template-columns: 200px 1fr;
  border-radius: 10px;
  height: 95vh;
  width: 100%;
}

.chat-title {
  padding: 10px;
  background: blue;
  grid-area: chat-title;   /*  added */
}

.chat-list {
  padding: 10px;
  background: red;
  grid-area: chat-list;   /*  added */
}

.message-list {
  padding: 10px;
  background: green;
  grid-area: message-list;   /*  added */
}

.chat-form {
  padding: 10px;
  background: yellow;
  grid-area: chat-form;   /*  added */
}

<div class="chat-container">
  <section class="chat-list">
    Chat List
  </section>
  <section class="chat-title">Chat title</section>
  <section class="message-list">
    Message List
  </section>
  <section class="chat-form">Chat form</section>
</div>
