我要在幻灯片显示中一排显示2个div吗？ 一部分是图像，第二部分是图例和文本。

我正在尝试使用flexbox来做到这一点，但是它不起作用，我也不明白为什么。

我介绍了一个带有ID（幻灯片）的div进行测试，但是带有图像的div和div class =“ text”仍然垂直对齐

你能帮我吗？

我添加了一个Codepen，它可以解决您的问题，您可以在其中检查我对标记所做的更改。

Flexbox是一种显示布局方法，因此我已将float:flex替换为display:flex。然后，我添加了一些其他样式规则，这导致2列的布局，每列是flexbox容器宽度的50％（由于必须定义宽度才能正常工作，因此我将宽度设置为75vw，等于浏览器屏幕宽度的75％。

每个“幻灯片”的标记都必须相同才能使布局生效，因此我将样式规则#slideshow更改为.mySlides，并确保图像位于div标签，我看到您已将其添加到第一张幻灯片中。

这是必需的样式（设置了一些边框颜色，以便您查看发生了什么情况）：

.mySlides{
    display: flex;
    flex-direction: row;
    width: 75vw;
    border: 1px solid red;
}
.mySlides > div {
    flex: 0 0 50%;
    border: 1px solid green;
}

flex: 0 0 50%是一种速记方式，但是在这种情况下，它指示每一列至少占用50％的宽度。

我还做了其他一些小的修改，但这些修改大多是装饰性的。

我希望这是有用的。欢迎提问：-）

代码问题是错误的属性-float: flex，应为display: flex，您不能将其设置为#slideshow，因为javascript更新会将其更改为{{1 }}。
