如何使CSS粘性与Flex问题一起工作

Question

我有一个HTML结构，我似乎无法使CSS位置粘性工作。

我认为是因为它在aside容器内。如果我aside坚持下去，它就会起作用。

我希望div.product-info是粘性的，当它击中div 时.content-other它会解开粘。

除非使用flex，否则我可以从aside内移出.personal-info和.product-info，并让它们坐在彼此的右侧？喜欢

content | Personal info | Product info

然后不费心把包装放在一边？不确定如何使用flex堆叠这些。

body {
padding: 20px;
}
.container {
margin-left: auto;
margin-right: auto;
position: relative;
padding-bottom: 16px;
padding-top: 16px;
width: 100%;
display: flex;
}
.content {
position: relative;
max-width: 100%;
flex-basis: 74%;
border: 1px solid black;
width: 300px;
margin-right: 20px;
height: 540px;
}
.right-side {
align-self: flex-start;
background-color: #ffffff;
border: 2px solid #e8e8e3;
border-radius: 0 4px 4px 4px;
flex: 1 1;
flex-basis: 40%;
min-width: 338px;
padding: 16px 16px 0;
display: block;
width: 400px;
}
.personal-info {
height: 250px;
}
.product-info {
position: sticky;
position: -webkit-sticky;
top: 24px;
border: 1px solid red;
}
.content-other {
width: 100%;
background: #f5f5f5;
height: 400px;
}

<div class="container">
<div class="content">content area here</div>
<aside class="right-side">
<div class="personal-info">some info</div>
<div class="product-info">sticky info</div>
</aside>
</div>
<div class="content-other">.product-info unsticks when it hits here</div>

干杯

只需删除align-self: flex-start;

body {
padding: 20px;
}
.container {
margin-left: auto;
margin-right: auto;
position: relative;
padding-bottom: 16px;
padding-top: 16px;
width: 100%;
display: flex;
}
.content {
position: relative;
max-width: 100%;
flex-basis: 74%;
border: 1px solid black;
width: 300px;
margin-right: 20px;
height: 540px;
}
.right-side {
/*align-self: flex-start;*/
background-color: #ffffff;
border: 2px solid #e8e8e3;
border-radius: 0 4px 4px 4px;
flex: 1 1;
flex-basis: 40%;
min-width: 338px;
padding: 16px 16px 0;
display: block;
width: 400px;
}
.personal-info {
height: 250px;
}
.product-info {
position: sticky;
position: -webkit-sticky;
top: 24px;
border: 1px solid red;
}
.content-other {
width: 100%;
background: #f5f5f5;
height: 400px;
}

<div class="container">
<div class="content">content area here</div>
<aside class="right-side">
<div class="personal-info">some info</div>
<div class="product-info">sticky info</div>
</aside>
</div>
<div class="content-other">.product-info unsticks when it hits here</div>
