HTML Button 在使用 Dreamweaver 时不响应 CSS

Question

大家好，我的 HMTL 有问题，分配给它的 CSS 无法正常工作。该按钮有效，它将按应有的方式链接，但 CSS 没有影响它。 我使用dreamweaver CC，在设计视图中似乎CSS正在运行，但是一旦我在浏览器上实时查看它，它就会恢复到原始状态，我将提供一些代码图片和实时视图来向您展示我的意思。

我的 HTML

<a href="methandrailhome.html" class="returnhome">Return Home</a><!-- end .returnhome -->

我的 CSS

#form .returnhome {

    -moz-box-shadow:inset -4px 2px 0px -13px #ffffff;
    -webkit-box-shadow:inset -4px 2px 0px -13px #ffffff;
