删除边框

Question

我正在尝试从iframe框中删除灰色边框，但遇到了困难。

代码如下，去掉了源代码。我还附上了一个显示边界的screenshot

    <!DOCTYPE html>
<html>
  <head>
    <style></style>
  </head>
  <body>
    <iframe
      frameborder="0"
      height="100%"
      src=""
      width="100%"
    >
      <p>Your browser does not support iframes.</p>
    </iframe>
  </body>
</html>

Answer 1

Body标签通过default.Try this放置8px的边距。

   <!DOCTYPE html>
<html>
  <head>

  </head>
  <body>
    <style>
     body{ margin:0px;padding:0px; }
    </style>
    <iframe
      frameborder="0"
      height="100%"
      src=""
      width="100%"
    >
      <p>Your browser does not support iframes.</p>
    </iframe>
  </body>
</html>

Answer 2

使用(我认为上面的拼写错误)

<!DOCTYPE html>
<html>
  <head>
    <style></style>
  </head>
  <body>
    <iframe
      frameBorder="0"
      height="100%"
      src=""
      width="100%"
    >
      <p>Your browser does not support iframes.</p>
    </iframe>
  </body>
</html>
