我在 .php 中尝试使用的表单存在问题

我在表格中使用表格来格式化我希望表格的外观。表单工作正常。但是当我加载页面时，页面顶部有一个巨大的空白，但我不知道它为什么会在那里。我已经尝试在网络浏览器中查看源代码，并且没有 html 空白字符或任何异常。这是我的代码：

<?php
$strRequester  = $_SERVER['PHP_SELF'];
echo "<div align=center>\n";
echo "<form name='SandwichOrder' action='$strRequester' method='POST'>\n";
####Bread####
echo "<table>\n";
echo "<tr><td bgcolor='CCCCCC'><input type='radio' name='size' value='whole'><b>Whole Sandwich</b></td>\n";

echo "<input type='SUBMIT' name='SUBMIT' value='Add to Order'><br>\n";
echo "<input type='button' name='CANCEL' value='Cancel Item'>\n";
echo "</form>";
echo "</div>\n";
?>

我也尝试将整个表格放入表格中，但这也无济于事。任何建议都会很棒。我对 .php 和 html 还很陌生，所以在解决这个问题时我什至不知道从哪里开始。

您是否将表单回显到 html 文档中？IE

<!doctype html>
<html>
<head>
<title>Title of the document</title>
</head>

<body>
 YOUR FORM HERE
</body>

</html>

( http://www.w3schools.com/tags/tag_body.asp )

您的 div 或 html 上可能有默认样式。在你的 CSS 中尝试：

html, body {
  height: 100%;
  width: 100%;
  margin: 0;
}

div {
   margin: 0;
}
