在弹性框中行换行居中对齐

Question

目前我正在尝试使用 flexbox 将我的列居中，但在调整浏览器大小时它粘在左侧。我已经尝试证明内容中心和对齐项目中心的合理性，但我可能没有将它们放在正确的位置。 如果有人知道如何解决这个问题，将不胜感激！谢谢！

.wrap{
	display:flex;
}
main{
	flex:1;
	display:flex;
}
aside, article{
    padding:2em;	
}
aside{
	flex:1;
}
article{
	flex:1;
}
@media (max-width: 800px) {
  main {
    flex-direction: column;
  }
}

<div class="wrap">
    <main>
        <aside>
            <h1>Do You Want to...</h1>
            <ul>
                <li>Rebrand myself online</li>
                <li>Take my current website and make it modern</li>
                <li>Find a way to make information more accessible for customers</li>
                <li> Improve customer service</li>
                <li> Reach a wider range of people</li>
            </ul>
        </aside>
        <article>
            <h1>Do You Want to...</h1>
            <ul>
                <li>Create forms and documents that customers can fill out online</li>
                <li>Start an email list for recurring customers</li>
                <li>Show relatability with my audience</li>
                <li> Have 24/7 online exposure</li>
                <li>Create a map or a way for customers to find my location</li>
            </ul>
        </article>
    </main>
</div>

Answer 1

要在移动视图上居中堆叠柱形图，请使用 align-items: center on main 。 对于桌面视图，可以通过指定 flex: 0 auto 来折叠列。 这表示不应允许项目增长，并应使用自动宽度。 然后，将justify-content: center添加到main以使折叠的列居中。

.wrap{
	display:flex;
	
}
main{
	flex:1;
	display:flex;
	justify-content: center;
}
aside, article{
padding:2em;	
}
aside{
	flex:0 auto;
}
article{
	flex:0 auto;
}
@media (max-width: 800px) {
  main {
    flex-direction: column;
    align-items: center;
  }
}

<div class="wrap">
<main>
<aside>
	<h1>Do You Want to...</h1>
    <ul>
  <li>Rebrand myself online</li>
  <li>Take my current website and make it modern</li>
  <li>Find a way to make information more accessible for customers</li>
  <li> Improve customer service</li>
  <li> Reach a wider range of people</li>
</ul>
</aside>
<article>
<h1>Do You Want to...</h1>
<ul>
  <li>Create forms and documents that customers can fill out online</li>
  <li>Start an email list for recurring customers</li>
  <li>Show relatability with my audience</li>
  <li> Have 24/7 online exposure</li>
  <li>Create a map or a way for customers to find my location</li>
</ul>
</article>
</main>
</div>
