Flexbox无法调整浏览器的大小

时间：2018-10-24 16:38:29

标签： html css html5 css3 flexbox

我正在尝试让我的Flexbox在移动设备和窗口大小上进行调整。

对于我的一生，我不知道为什么它不起作用。当浏览器缩小时，flexbox应该调整大小并环绕到下一行。

随着浏览器窗口分辨率的变小，我想在左侧的右侧进行换行，但是我似乎无法弄清楚。

flexbox右侧的内容被隐藏，仅使用CSS关键帧从顶部滑入。我猜这可能是个问题，因为flexbox右侧的内容div本质上是空的

Michael_B在这里很好地说明了问题。

除了他的回答外，我只想说您也在使用绝对.content，因此您的flexbox不是“普通” flexbox。

顺便说一句，我尝试使用您的HTML使其负责。诀窍是删除所有固定宽度。

引导程序是一种可能的方法，但是如果您已经开始工作，则可以仅使用CSS属性而无需使用javascript（如您所做的那样）来完成它： CSS具有所有凭据，而无需框架。这就是我的想法。

我试图不更改您的HTML。我仅删除了<div id="middle-border"></div>，因为您可以在#left-zone .list属性的帮助下在box-sizing中创建右边框...并且自然是border-right；）

在您的CSS中，我使用更简单的不透明度和translationY过渡更改了动画（您必须在没有其他动画的情况下从A点到B点进行过渡，所以我认为过渡就足够了）。但是，嗯，使用动画并不是一个错误，我认为只有更简单的过渡使用这项工作。

另一个重要的想法是使用CSS，以在HTML元素的默认样式中提供更好的跨浏览器一致性。为此，我使用了“ normalize.css”：https://necolas.github.io/normalize.css/）

这是代码，希望对您有所帮助：

弹性物品包装在其容器中。听起来很明显，但这是这里要理解的关键概念。

如果flex项目位于宽度与视口宽度相关的容器中-通常是一个容器，该容器占用width: 100%元素的body –那么flex项目将相对于视口宽度。调整视口的大小将对flex容器产生直接影响，这将对flex项产生直接影响。

但是，在您的情况下，flex容器不绑定到视口宽度。它具有不同的宽度：

#flex-container {
  display: flex;
  flex-wrap: wrap;
  width: 1000px;
}

在这种情况下，弹性项目是相对于1000px宽的空间而不是视口空间进行布局的。由于项目和视口没有关联，因此在调整视口大小时，项目没有理由做任何事情。

好吧，经过一段时间的努力，我有了使用Bootstrap 4和Animate.css插件替换动画的下一个（响应）方法。我希望你喜欢它！

$(document).ready(function()
{
    $("input[type='radio']").click(function()
    {
        $("#right-zone .animated").addClass("d-none");
        var target = $(this).attr("target-div");
        $("." + target).toggleClass("d-none");
    });
});
#flex-container {
    min-height: 50vh;
    margin-top: 25vh;
    box-shadow: 0 1px 3px rgba(0, 0, 0, 0.12), 0 1px 2px rgba(0, 0, 0, 0.24);
}

/* On XS screen devices, use all the available height */

@media(max-width:576px)
{
    #flex-container {
        min-height: 100vh;
        margin-top: 0vh;
    }
}

#right-zone {
    background-color: rgba(255,0,0,0.6);

答案 3 :(得分：0)

这是因为您将flex-wrap属性赋予了错误的元素。 整个#left-zone是#flex-container元素的一个孩子。您需要更改div的放置顺序，以使列表位于一个div中，而内容部分为另一个div。然后，内容将自动换行。
