这实际上非常简单，仅几行CSS代码：
div{
width:60%;
margin-right:auto;
margin-left:auto;
background-color:red;
}
这是根据您的代码的完整html示例：
Welcome to Wumbo.Net!::-moz-selection { /* Code for Firefox */
color: #ffffff;
background: #00ffaa;
}
::selection {
color: #ffffff;
background: #00ffaa;
}
/* unvisited link */
a:link {
color: #00ffaa;
}
/* visited link */
a:visited {
color: #00d486;
}
/* mouse over link */
a:hover {
color: #57ffd5;
}
/* selected link */
a:active {
color: #00ffaa;
}
#center{
width:60%;
margin-right:auto;
margin-left:auto;
background-color:white;
}
This Site is Under Construction!
In a few months, when I am finished, I will unveil this site! In the meantime,
also for updates, follow me on twitter.
I also have a Youtube channel where I upload stupid crap!
MY SOCIAL NETWORKZ
My Youtube Channel
My Newgrounds (I'm not super active on it)
I'm not sure what I'm going to do with this site,
But it will most likely be a portfolio, where I share all the drawings,
animations and other such things I've made.
Seeya!
