html - 当用于根据内容改变宽度时，内联 block 不适用于网格

Question

我正在使用网格，但我面临的问题是行内 block 无法使用它。即我希望我的 div 的高度和宽度随其中的内容而变化。如果我不使用网格那么它工作正常但是使用网格它会拉伸(stretch)到列的宽度

.BotWrapper {
  position: relative;
  width: 100%;
  display: grid;
  grid-template-columns: repeat(2, 1fr);
  grid-gap: 1em;
  grid-auto-rows: minmax(20px, auto);
  margin-top: 0.8em;
  word-wrap: break-word;
}

.BotWrapper > div {
  margin-left: 2%;

}

.speech-bubble {
  padding: 5rem;
  border: 2px solid #376996;
  border-top-right-radius: .6em;
  border-bottom-right-radius: .6em;
  border-bottom-left-radius: .6em;
}

.speech-bubble1 {
  position: relative;
  background: #62B6CB;
  border: 2px solid #376996;

.timeRight {
  font-size: 0.52em;
  float: right;
  margin-top: -1em;
  margin-bottom: 0;
  font-family: 'Mina', sans-serif;
}

.timeLeft {
  font-size: 0.52em;
  float: right;
  margin-top: -1em;
  margin-bottom: 0;
  font-family: 'Mina', sans-serif;
}

<div class="msgContainer" id="chat">
  <div class="BotWrapper">
    <div class="speech-bubble z-depth-5">
      <p>Hi</p>
      <p class="timeLeft">02:12:02</p>
    </div>
    <div class=""></div>
  </div>

  <div class="UserWrapper">
    <div class=""></div>
    <div class="speech-bubble1 z-depth-5">
      <p>Bye</p>
      <p class="timeRight">02:12:03</p>
    </div>
  </div>
</div>

第一个 div 是我使用网格的时候，第二个是我从 UserWrapper 中删除了 . 所以它不是作为 grid 执行。为什么会这样？

Answer 1

我认为您正在寻找的是容器上的justify-items: start。这会将元素对齐到与其单元格的起始边缘齐平，而默认设置是 stretch 这会强制子项填充单元格的整个宽度
