Question

在下面的代码中，我将我的顶部徽标设置为min-width：800px，这样用户就无法调整大小并弄乱我的导航。但是，由于某种原因它不起作用。有人能告诉我我做错了吗？

Answer 1

您的min-width位于容器<div>上，但是为了做您正在尝试的事情，您可能会想要img本身。

另一种选择是将其设置为div#logo的背景图片，但我不确定这是否适合您的用例。

    }

Answer 3

试试这个

#logo {
    background-color: black;
    width: 800px;
    color: rgb(255,200,0);
    height: 100px;
    margin-left:auto;
    margin-right:auto;
}
