html - 如何设置通知警报的高度和宽度

Question

我有一个注册页面。当我完成注册并单击保存按钮时，我会收到“注册成功”的通知。我使用 bigbox.css 和 humane.js 作为我的通知。我很容易收到通知，但问题是通知有默认的 height 和 width 。如何自定义其高度和宽度？

   var ratPack = $.sammy(function() {
        this.post('#/cart', function() {
           var firstname = this.params['firstName'];
    var lastname = this.params['lastName'];
    var organisation = this.params['organisation'];
    var email = this.params['email'];
    var password = this.params['password'];
    var confirmPassword = this.params['confirmPassword'];
    var baseurl = this.params['url'];
           $.ajax({
        type : 'POST',
        url :'/costing-
     tool/api/registration/'+firstname+'/'+lastname+'/'+email,
        success : function() {
         document.getElementById('light').style.display='none';
             document.getElementById('fade').style.display='none';
             humane.log("Registration Successful");//humane used here
                    },
        error:function(){
            alert($('#emailError'));
            $('#emailError').text("This E-Mail is already registered")
        }
   });
});
  });

我看到您对 CSS 非常陌生，但是您可以将大框宽度更改为父元素宽度的 50%。关于 bigbox 高度，默认情况下设置为自动(这就是为什么您现在看不到它的原因)并且您将 min-height 设置为 40px，以防 bigbox 中没有列表或文本。

.humane-bigbox {
   font-family: Ubuntu, Verdana, sans-serif;
   line-height: 40px;
   font-size: 20px;
   top: 25%;
   left: 25%;
   opacity: 0;
   width: 50%; <- This is the width value
   min-height: 40px;
   ...
}
