尽管代码相同，但在不同位置切换面板

Question

我的问题是由于 jQuery toggle() 方法，我有两个面板显示和隐藏。在 jQuery 方面，我完全是个菜鸟，我使用教程制作了一个面板，然后使用相同的代码制作了第二个面板。最后，新的看起来比第一个低很多，我不知道如何修复它。此外，新面板几乎覆盖了网站的整个部分，除了在面板顶部清晰可见的菜单链接之外，它不应该像那样。我该如何解决？

$(document).ready(function(){
    $('#cards div:not(:first)').hide();
    
    $('#list li').click(function(e){
        $('#cards div').hide();
        $('#list .current').removeClass("current").children().removeClass("open");
        $(this).addClass('current');
        $(this).children().addClass('open');
        
        var clicked = $(this).find('a:first').attr('href');
        $('#cards ' + clicked).fadeIn('fast');
        e.preventDefault();
    }).eq(0).addClass('current');
    
    $('.form_container').hide();
    $('button.trigger').click(function(){
       $(this).toggleClass("active").next().slideToggle("slow");
       return false;
    });
});

Answer 1

问题在这里：

#log_in {
    float: right;
}

因为该元素浮动在文档流之外，所以它不会将其他元素向下推。删除它，然后调整 .form-container 的上边距以更好地适应：

.form_container {
    margin-top: 5px;
}
