我目前正在建立一个网站，因为我已经完成了标题标记，我应用了position：fixed;怎么会敲掉我的标题，我不知道为什么我在css中尝试调试整个标题标记。
任何帮助将不胜感激：
$(document).ready(function(){
$('#login-trigger').click(function(){
$(this).next('#login-content').slideToggle();
$(this).toggleClass('active');
if ($(this).hasClass('active')) $(this).find('span').html('▲')
else $(this).find('span').html('▼')
})
});
function f_p(){
document.getElementById('forgot_pwd').style.display='block';
document.getElementById('userlogin').style.display='none';
}
function p_f(){
document.getElementById('forgot_pwd').style.display='none';
document.getElementById('userlogin').style.display='block';

答案 1 :(得分：0)
您可以使用
粘贴标题此处示例：http://jsfiddle.net/vey2ea1t/
header {
position: fixed;
}
在几条评论之后编辑：
请使用：
<header style="position: fixed !important; width: 100%;">
并从标记nav中移除此css：
margin-left: auto;
