Question

我正在尝试将光标设置为所有标记<a>，但是当我查看网站时，该属性未显示

CSS

 a {
  color: #333333;
  /* color: #787878; */
  text-decoration: none;
  cursor: pointer
 }

在网站上

 a {
  color: #333333;
  /* color: #787878; */
  text-decoration: none;
 }

如果你想看看网站是：backlabel.com

问题是您的链接根本不是链接。

HTML是：

Expected output :

 Above mentioned five variables should be written by respective value and write a file

如果“链接”没有<a data-toggle="collapse" data-target="#demo">Care & Washing ▾</a>，那么它不是链接，它基本上被视为跨度。

由于您使用此作为“切换”，您可以添加

href

CSS游标属性不起作用
