html - 尝试创建列 HTML CSS

问题描述

我有一个我创建的列表，其中包含类名。目前，当您加载页面时，您会看到所有内容，但是是垂直的。

我想要做的是使每个浏览器大小的列大小不同。我试图用列数来做到这一点，但我没有看到 3 列，它们仍然是垂直的。

例如 900px- 1280px：3 列显示 700px-900px：2 列显示 700px 以下：像现在这样垂直

3 列的图片：在此处输入图片描述

div h1{
    font-size: 2em;
}

li[data-offered-fall=yes]::before {
            font-family: FontAwesome;
            font-size: 0.75em;
            content: "\2705";
            display: inline-block;
            padding-left: 0.25em;
            color:red;
}

li[data-offered-fall=yes]::after {
            font-family: FontAwesome;
            font-size: 0.75em;
            content: li;
            display: inline-block;
            padding-left: 0.25em;
            color:red;
}

解决方案

这很简单，因为您在 li 中使用 column-count css 而不是成为 li 容器的 div。

所以你必须做的是，添加 div 的类并用 column-count 编写 div 的 css 代码。

@media screen and (max-width: 1280px)
{
    .container{
        column-count: 3;
    }
}

@media screen and (max-width: 900px)
{
    .container{
        column-count: 2;
    }
}

@media screen and (max-width: 700px)
{
    .container{
        column-count: 1;
    }
}

这里是小提琴。如果你正确阅读 w3 school 的例子，你会明白的。 这是 w3 的列数说明，别忘了添加 webkit 和 mozz
