滚动Scroll-Y不适用于Flexbox [英] overflow scroll-y not working with flexbox

问题描述

当新的div框(.dialog-box)添加到父容器(.dialog-container)时，我试图将div彼此堆叠".

I'm trying to "stack" divs on top of each other as new div boxes (.dialog-box) are added to the parent container (.dialog-container).

要堆叠元素，我在父对象上使用以下内容:

To stack the elements, I'm using the following on the parent:

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

我想滚动该容器以查找正在溢出的.dialog-box，但是使用flex-box时，overflow-y: scroll;不会滚动.

I'd like to scroll that container for .dialog-boxs that are overflowing, yet with flex-box the overflow-y: scroll; is not scrolling.

两个框:(按预期从底部到顶部填充容器):

Two boxes: (fill up container from bottom to top as expected):

六个框(在容器的高度之外展开并应滚动):

Six boxes (expands outside the height of the container and should scroll):

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>

推荐答案

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:

Two boxes: (fill up container from bottom to top as expected): for this you add below code to your scss file :

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>
