如何防止孩子的内容拉伸父母的宽度 [英] How to prevent child's content from stretching parent's width

问题描述

我有一个组件 (Container)，它包含一个图标(下面用 X 标记)、一个标题和一个子组件(Message>) 包含长消息.我希望 Container's 的宽度环绕图标和标题，因此两者都在一行上，只要窗口的宽度允许.

消息组件有一个按钮，可以切换长文本的显示.此文本不应拉伸父 Container，并且应与标题的宽度对齐.消息内容可以在任何时候被破坏和包装:

我使用了一个 flex-grow: 1;width: 0; 样式在 Message 中的虚拟 div 上按照建议

如何在 MS Edge 上解决此问题?是否有仅使用 CSS 的替代方法可以防止消息内容拉伸其父级?

Style.css:

.box {显示:表；保证金:自动；边框:1px纯黑色；}.容器 {显示:弹性；对齐内容:居中；}.图标 {右边距:10px；}.信息 {显示:弹性；}.message >div {弹性增长:1；宽度:0；断字:断断续续；}

Container.jsx:

export const Container = () =>{返回 (
X
一些标题
<消息>不应使父级更宽的长消息</消息>
);}

Message.jsx:

export const Message = ({children}) =>{const [isExpanded, setExpanded] = React.useState(false);const handleClick = () =>setExpanded(!isExpanded);返回 (<div><div><button onClick={handleClick}>点击</button>

{isExpanded &&

<div>{儿童}</div>

}

);}

解决方案

在消息容器上试试width:0;min-width:100%;:

.box {显示:表；保证金:自动；边框:1px纯黑色；}.容器 {显示:弹性；对齐内容:居中；}.图标 {右边距:10px；}信息 {显示:块；宽度:0；最小宽度:100%；}

<div class='container'>
X
<div class='content'>
一些标题
<留言><div>不应使父级变宽的长消息

或者到消息里面的div:

.box {显示:表；保证金:自动；边框:1px纯黑色；}.容器 {显示:弹性；对齐内容:居中；}.图标 {右边距:10px；}信息 {显示:块；}消息 >div {宽度:0；最小宽度:100%；}

<div class='container'>
X
<div class='content'>
一些标题
<留言><div>不应使父级变宽的长消息

I have a component (Container) that contains an icon (marked with an X below), a title and a child component (Message) that contains a long message. I would like Container's width to wrap around the icon and the title so both are on one line as much as window's width allows for it.

Message component has a button that toggles display of a long text. This text should not stretch the parent Container and it should be aligned with title's width. The message content can be broken and wrapped at any point:

I used a flex-grow: 1; width: 0; style on a dummy div in Message as suggested here to prevent it from growing. This works well on all browsers except for MS Edge, where the message content stretches the parent:

How can I fix this issue on MS Edge? Is there alternative way using only CSS that I can prevent the message content from stretching its parent?

Style.css:

.box {
  display: table;
  margin: auto;
  border: 1px solid black;
}

.container {
  display: flex;
  justify-content: center;
}

.icon {
  margin-right: 10px;
}

.message {
  display: flex;
}

.message > div {
  flex-grow: 1;
  width: 0;
  word-break: break-all;
}

Container.jsx:

export const Container = () => {
  return (
    <div className='box'>
      <div className='container'>
        <div className='icon'>
          X
        </div>
        <div className='content'>
          <div className='title'>
            Some title
          </div>
          <Message>
            Long message that should not make parent wider
          </Message>
        </div>
      </div>
    </div>
  );
}

Message.jsx:

export const Message = ({children}) => {
  const [isExpanded, setExpanded] = React.useState(false);

  const handleClick = () => setExpanded(!isExpanded);

  return (
    <div>
      <div>
        <button onClick={handleClick}>Click</button>
      </div>
      {isExpanded &&
        <div className='message'>
          <div>{children}</div>
        </div>
      }
    </div>
  );
}

解决方案

Try width:0;min-width:100%; on the message container:

.box {
  display: table;
  margin: auto;
  border: 1px solid black;
}

.container {
  display: flex;
  justify-content: center;
}

.icon {
  margin-right: 10px;
}

message {
  display:block;
  width:0;
  min-width:100%;
}

<div class='box'>
  <div class='container'>
    <div class='icon'>
      X
    </div>
    <div class='content'>
      <div class='title'>
        Some title
      </div>
      <message>
        <div>Long message that should not make parent wider</div>
      </message>
    </div>
  </div>
</div>

Or to the div inside the message:

.box {
  display: table;
  margin: auto;
  border: 1px solid black;
}

.container {
  display: flex;
  justify-content: center;
}

.icon {
  margin-right: 10px;
}

message {
  display:block;
}
message  > div {
  width:0;
  min-width:100%;
}

<div class='box'>
  <div class='container'>
    <div class='icon'>
      X
    </div>
    <div class='content'>
      <div class='title'>
        Some title
      </div>
      <message>
        <div>Long message that should not make parent wider</div>
      </message>
    </div>
  </div>
</div>
