Question

我试图＆＃34;堆叠＆＃34;当新的div框（.dialog-box）被添加到父容器（.dialog-container）时，div彼此重叠。

要堆叠元素，请在父级上使用以下内容：

display: flex;
flex-direction: column;
justify-content: flex-end;

我想滚动那个溢出的.dialog-box容器，但是使用flex-box overflow-y: scroll;不会滚动。

两个方框:(按预期从下到上填充容器）：

六个盒子（在容器的高度之外扩展并且应该滚动）：

SCSS：

.dialog-container {
    border: 4px solid rgba(255, 255, 255, .4);
    border-radius: 5px;
    width: 300px;
    height: 340px;
    position: relative;
    top: -50px;
    margin: 0 auto;
    overflow-y: scroll;
    z-index: 5;
    display: flex;
    flex-direction: column;
    justify-content: flex-end;

    .dialog-box {
        width: 90%;
        background: $dialogBoxWhite;
        margin-bottom: 20px;
        border-radius: 8px;
        border: 5px solid $dialogBoxGreenBorder;
        color: $dialogBoxGreenFont;
        text-align: center;
        margin-left: 5px;
        padding: 5px;
        display: inline-block;
        p {}
    }
}

HTML：

<div class="dialog-container">
   <div class="dialog-box"></div>
   <div class="dialog-box"></div>
   <div class="dialog-box"></div>
   <div class="dialog-box"></div>
   <div class="dialog-box"></div>
   <div class="dialog-box"></div>
</div>

Answer 1

您只需删除 justify-content：flex-end;

两个框：（按预期从底部到顶部填充容器）：为此，您将以下代码添加到您的scss文件：

display: flex;
flex-direction: column-reverse;
justify-content: flex-start;

.dialog-container {
    border: 4px solid rgba(0, 0, 0, .4);
    border-radius: 5px;
    width: 300px;
    height: 350px;
    position: relative;
    margin: 0 auto;
    overflow-y: scroll;
    z-index: 5;
    display: flex;
    flex-direction: column-reverse;
    justify-content: flex-start;
}
    .dialog-box {
        width: 90%;
        background:white;
        margin-bottom: 20px;
        border-radius: 8px;
        border: 5px solid green;
        color: green;
        text-align: center;
        margin-left: 5px;
        padding: 3px;
        display: inline-block;
        }

<div class="dialog-container">
   <div class="dialog-box">Box 1</div>
   <div class="dialog-box">Box 2</div>
   <div class="dialog-box">Box 3</div>
   <div class="dialog-box">Box 4</div>
   <div class="dialog-box">Box 5</div>
   <div class="dialog-box">Box 6</div>
    <div class="dialog-box">Box 7</div>
</div>

还在scroll-y working with flex-column

中显示示例

Answer 2

更新答案，我混淆了flex-direction的值。

'row'右边不是'column'

在.dialog-container

中添加css

flex-direction: row;

flex-wrap : wrap;

或

flex-flow: row wrap

Answer 3

尝试将display: flex;更改为display: flex-box;

这将为您提供实际滚动的滚动条。此外，您的示例div都缺少结束标记。

<div class="dialog-container">
   <div class="dialog-box">9</div>
   <div class="dialog-box">8</div>
   <div class="dialog-box">7</div>
   <div class="dialog-box">6</div>
   <div class="dialog-box">5</div>
   <div class="dialog-box">4</div>
   <div class="dialog-box">3</div>
   <div class="dialog-box">2</div>
   <div class="dialog-box">1</div>
</div>


.dialog-container {
    border: 4px solid rgba(255, 255, 255, .4);
    border-radius: 5px;
    width: 300px;
    height: 340px;
    position: relative;
    top: 50px;
    margin: 0 auto;
    z-index: 5;
    display: flex-box;
    flex-direction: column;
    justify-content: flex-end;
    overflow-y: auto;
    background-color: teal;


    .dialog-box {
        width: 90%;
        background: black;
        margin-bottom: 20px;
        border-radius: 8px;
        border: 5px solid red;
        color: green;
        text-align: center;
        margin-left: 5px;
        padding: 5px;
        display: inline-block;
        p {}
    }
}

溢出滚动-y不适用于flexbox
