使flex容器占用内容的宽度，而不是宽度的100％

问题描述

在下面的例子中，我有一个按钮，样式如下：

  .button-flexbox-approach { 
 / *其他按钮样式* / 
 display：flex; 
 justify-content：center; 
 align-items：center; 
填充：1.5rem 2rem; 
 
  

但它会自动缩放到100％内容的宽度。你可以设置一个明确的宽度，但不允许你的文本自然地包装。

如何制作一个按钮，其中的内部文本以flexbox为中心，但不会增长以适应容器的大小？

.container {width：100％;高度：100％;}。button {/ *只需弯曲按钮使其长到容器的大小...我们如何才能使其内容的大小只有它的内容？ * / display：flex; justify-content：center; align-items：center; -webkit-appearance：none; border-radius：0;边框式：坚固; border-width：0;光标：指针; font-weight：正常; line-height：正常;保证金：0;位置：相对; text-align：center;文字修饰：无;填充：1rem 2rem 1.0625rem 2rem; font-size：1rem; background-color：＃D60C8B; border-color：＃ab0a6f;颜色：#fff;}一个{margin-bottom：1rem;}。两个{/ *你可以放一个明确的宽度，但是你失去了灵活性的内容* /宽度：250px;} < div class =container>

解决方案在容器上使用 display：inline-flex 来代替显示：flex / p>

这将容器从块级别切换到内联级别（取其内容的宽度）。

这个尺寸行为类似于 display：block vs display：inline-block

In the below example, I have a button with the following styles...

.button-flexbox-approach {
    /* other button styles */
    display: flex;
    justify-content: center;
    align-items: center;
    padding: 1.5rem 2rem;
}

But it automatically scales to 100% instead of the width of the content. You can set an explicit width, but then that doesn't allow your text to wrap naturally.

How can I make a button that has the inner text centered with flexbox, but doesn't grow to fit the size of the container?

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

.button {
/*   Simply flexing the button makes it grow to the size of the container... How do we make it only the size of the content inside it? */
  display: flex;
  justify-content: center;
  align-items: center;
  -webkit-appearance: none;
  border-radius: 0;
  border-style: solid;
  border-width: 0;
  cursor: pointer;
  font-weight: normal;
  line-height: normal;
  margin: 0;
  position: relative;
  text-align: center;
  text-decoration: none;
  padding: 1rem 2rem 1.0625rem 2rem;
  font-size: 1rem;
  background-color: #D60C8B;
  border-color: #ab0a6f;
  color: #fff;
}

.one {
  margin-bottom: 1rem;
}

.two {
/* You can put an explicit width on that, but then you lose the flexibility with the content inside */
  width: 250px;
}

<div class="container">
  <p>
    Button one is flexed with no width and it grows to the size of its container
  </p>
  <p>
    <a class="button one" href="#">Button</a>
  </p>
  <p>
    Button two is flexed with an explicit width which makes it smaller, but we have no flexibility for changing the content
  </p>
  <p>
    <a class="button two" href="#">Button 2</a>
  </p>
</div>

解决方案

Instead of display: flex on the container, use display: inline-flex.

This switches the container from block-level (which takes the full width of its parent) to inline-level (which takes the width of its content).

This sizing behavior is similar to display: block vs. display: inline-block.
