我遇到了我的项目的登录/注册html页面的问题：
- 隐藏CSS类因某些原因不适用
第一个就是你可以看到.hide（display：none;）由于某种原因没有生效，这使得登录表单显示在主容器旁边。
-JQuery addClass（）/ removeClass（）无效。
第二个问题是我的jquery函数显示登录表单并在单击Register时隐藏寄存器表单不起作用，使用addClass（.hide）和removeClass（.hide）在寄存器和登录表单之间交替点击，我认为这是上帝的行为，。
这是我的代码：
$('#showLoginForm').click(function(e){
e.preventDefault();
//alert('clicked register');
$('.auth_register_container').addClass('hide');
$('.auth_login_container').removeClass('hide');
});*{box-sizing:border-box; margin:0; padding:0;}

答案 0 :(得分：0)
.hide的{{1}}被display: none和.auth_login_container的{{1}}覆盖。
jQuery的.auth_register_container和display: flex在没有这些重写样式的情况下正常工作。
如果将addClass样式移动到其他两个类的样式之下，应用程序将按预期工作。例如https://jsfiddle.net/xpvt214o/171674/
另一种技术是在removeClass样式之后添加.hide，因此它会覆盖其他!important样式。我知道display: none有时会被滥用，但这似乎是一个合理的用例。
