CSS在Chrome中不起作用，但在Firefox中有效

Question

我有一段CSS代码在Firefox中运行良好，但在Chrome中运行不正常。 我猜使用-webkit-linear-gradient时显示错误，这在Chrome中显示无效值

HTML code：

<div class="laptop">
    <div class="glare-xl"></div>
    <div class="screen-xl">
        <img src="http://www.psdgraphics.com/file/silver-laptop-icon.jpg" alt="laptop" />  
    </div>
    <div class="base-xl"></div>
    <div class="addons-xl "></div>
    <div class="button-xl"></div>
</div>

CSS代码：

问题：

1）为什么CSS在Chrome中不起作用

2）我如何能够将所有这些结构，即笔记本电脑作为响应，因为我在所有地方尝试了最大宽度，但它不起作用？

您需要删除/替换center功能中的linear-gradient()关键字。根据{{​​3}}，没有这样的事情。
