javascript - 为什么负 margin 不起作用？

Question

当您单击“恢复”时，一些文本会从左侧出现。这是因为我最初给文本留了负边距。

但是 intro_page 的负边距没有效果。

我想要的是:

1. 当我点击 resume_page 时，resume 的文本应该从左边进入(这有效)而 intro_page 的文本应该从右边出来(这不起作用' 工作)。

   intro_page 的负边距似乎不起作用。这是为什么？

2. 最初，除了两个链接外，页面应该是空的。当前，intro_page 页面显示。 resume_page 已根据需要正确隐藏。

简而言之，resume_page 的一切都完美无缺。我希望 intro_page

发生完全相同的事情

function clicked_resume(OnScreen)
{
    var resume = document.getElementById('resume_page');
    if(OnScreen == 1)
    {
        resume.className = '';
        clicked_about(0);
    }
    else if(OnScreen == 0)
    {
        resume.className = 'unseen';
    }
    
}

function clicked_about(OnScreen)
{
   
    var about = document.getElementById('intro_page');
    if(OnScreen == 1)
    {
        about.className = '';
        clicked_resume(0);

    }
    else if(OnScreen == 0)
    {
        about.className = 'unseen';
    }
}

#intro_page.unseen{
	display: block;
	margin-right: -200px;
}


#intro_page{
	margin-right: 0px;
	display: block;
	-webkit-transition: margin-right 1.5s ease-in;
	transition: margin-right 1.5s ease-in;
}

#resume_page.unseen{

	margin-left: -600px;
}

#resume_page{
	margin-left: 0px;
	display: block;
	-webkit-transition: margin-left 1.0s ease-in;
	transition: margin-left 1.0s ease-in;
}

尝试使用 position: relative 和 right 而不是 margin-right。它更可靠，因为它在定位其他元素时不考虑元素的位置，就像 margin 那样。对于奖励积分，您甚至可以使用 transform:translate 而不是 right。

function clicked_resume(OnScreen)
{
    var resume = document.getElementById('resume_page');
    if(OnScreen == 1)
    {
        resume.className = '';
        clicked_about(0);
    }
    else if(OnScreen == 0)
    {
        resume.className = 'unseen';
    }
    
}

function clicked_about(OnScreen)
{
   
    var about = document.getElementById('intro_page');
    if(OnScreen == 1)
    {
        about.className = '';
        clicked_resume(0);

    }
    else if(OnScreen == 0)
    {
        about.className = 'unseen';
    }
}

body {
    margin: 0;
    overflow-x: hidden;
}

#intro_page.unseen{
    display: block;
	right: -100%;
}


#intro_page{
	position: relative;
    right: 0px;
	display: block;
	-webkit-transition: right 1.5s ease-in;
	transition: right 1.5s ease-in;
}

#resume_page.unseen{
	display: block;
	left: -600px;
}

#resume_page{
	position: relative;
    left: 0px;
	display: block;
	-webkit-transition: left 1.0s ease-in;
	transition: left 1.0s ease-in;
}

<h2 class="title_bar">
<ul>
					
	<li><span onclick = "clicked_about(1)">About</span></li>
	<li><span onclick="clicked_resume(1)">Resume</span></li>
</ul>
