html - 尝试创建列 HTML CSS

Question

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

我想做的是让每个浏览器大小的列大小都不同。我试着用列数来做到这一点，但我没有看到 3 列，它们仍然都是垂直的。

例如 900px- 1280px:分3列显示 700px-900px:分两列显示 低于 700px:像现在一样垂直

3 列的图片:enter image description here

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;
}

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

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

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

Answer 1

这很简单，因为您在 li 中使用列计数 css 而不是成为 li 容器的 div。

所以你必须做的是，添加 div 的类并用列数编写 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;
    }
}

Here the Fiddle .如果你正确阅读了 w3 学校的例子，你就会明白。 And here's the column-count description at w3, don't forget add the webkit and mozz
