html小白一个。遇到的代码想将它居中，然后尝试了align="center"和
都没有效果。代码精简后是这样的： <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>待居中</title>
<style type="text/css">
