我可以隐藏我的意思菜单jquery的文本和按钮吗?

Question

所以基本上我为我的网站使用模板并相应地进行调整。该站点定义了要在开始时隐藏的菜单栏，并在向下滚动时显示。

但是，文本和菜单按钮始终显示在"开始"菜单上。我不明白我怎么能告诉文本（电子邮件和电话号码）与菜单栏的其余部分保持隐藏。

Answer 1

  $(document).on('scroll',function(){
  $(".hamburger-menu").slideDown(); //i have used slide down function for animation, you can change class or add css display type changing properties 
  })

.makescroll{height:1000px;}
.hamburger-menu{display:none}
