Question

我尝试使用CSS创建一个简单的网格系统，类似于bootstrap。这是page at CodePen。 CSS代码为：

    /*
* light blue = 00AEEF
* dark blue = 1C75BC
* green = 8DC63F
* dark green = 009444
* orange = F7941E
* dark orange = F15A29
* brown = 594A42
*/

h1, h2, h3{
    font-weight: bold;

a{

a:hover{

/* ":after" is a pseudo-element (NOT a pseudo-class) */

[class*='col-']{
    width: 100%;
    padding-left: 15px;
    padding-right: 15px;
}

/* Media query excludes extra-small devices and includes small and above */
@media (min-width: 48em) {
    [class*='col-']{
        float: left;

    }

    /* Column One Third */
    .col-1-3{
        width: 33.3333%;
        background: red;
    }

    /* Column Two Thirds */
    .col-2-3{
        width: 66.6666%;
        background: blue;
    }
}

.background-secondary{

    <section>
        <div class="container">
            Featured Content
        </div>
    </section>

    <section class="background-primary">
        <div class="container">
            Testimonial Content
        </div>
    </section>

    <section class="background-secondary">
        <div class="container">

    <section class="background-tertiary">
        <div class="container">
            More Content
        </div>
    </section>
  </main>

  <footer class="background-primary">
    <div class="container">
        Footer Content
    </div>
  </footer>

在IE和Edge中，两者都是＆＃34;圆形图像＆＃34;和＆＃34;内容区＆＃34;按预期漂浮并水平显示。但是当在Chrome或Firefox中查看时，它们是垂直堆叠的（至少在我身边）。我怀疑这是因为填充，但为什么IE能够正确处理它而其他浏览器失败？这是一个已知错误吗？

（如果这是一个天真的问题，我很抱歉;但我是网络开发的新手）

Answer 1

既然你说＆＃34;类似于bootstrap＆＃34; 我将假设 你没有使用/不愿意使用它（为什么？）

现在，让我们谈谈网格。

在网格中，需要指定某些维度才能使其正常运行。我也会将整个事情包裹在<div>中以包含它。

如果您这样做并且告诉元素是好的并且不超过其父容器的宽度 - 使用{max-width:100%} - 您会得到一个很好的响应网格。像这样：

（在全屏中打开代码段并调整大小您的窗口，以根据屏幕宽度查看元素堆叠/解除堆叠的方式）

CSS Grid列不会在Chrome和Firefox中浮动，但在IE和Edge中也是如此
