css - 固定位置有问题。

标签 css header position

我目前正在 build 一个网站，因为我已经完成了标题标签，所以我应用了position:fixed;它是如何破坏我的标题的，我不知道为什么，因为我尝试在 css 中调试整个标题标签。

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';
}

最佳答案

您可以使用

粘贴标题

此处示例:http://jsfiddle.net/vey2ea1t/ 

header {
position: fixed;
}

几条评论后编辑:

请使用:

<header style="position: fixed !important; width: 100%;">

并从标签 nav 中删除此 css:

margin-left: auto;
