embed PDF file in html using object tag

I m embeding a pdf document into my html code. For this i have wrote this code.

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org

/TR/html4/loose.dtd">
<html lang="en">
<head>
    <meta http-equiv="Content-Type" content="text/html;charset=UTF-8">
    <title></title>
</head>
<body>
<object height="100%" width="100%" type="application/pdf" data="yii.pdf#toolbar=1&amp;navpanes=0&amp;scrollbar=1&amp;page=1&amp;view=FitH">

<p>It appears you don't have a PDF plugin for this browser. No biggie... you can <a href="/pdf/sample.pdf">click here to download the PDF file.</a></p>

</object>

</body>
</html>

But result is empty page on FF4 and IE9 embeds pdf file but its container is very small almost 30% of page. if I remove first line i.e DOCTYPE both browsers renders pdf file as it should. Following code works fine.

<html lang="en">
<head>
    <meta http-equiv="Content-Type" content="text/html;charset=UTF-8">
    <title></title>
</head>
<body>
<object height="100%" width="100%" type="application/pdf" data="yii.pdf#toolbar=1&amp;navpanes=0&amp;scrollbar=1&amp;page=1&amp;view=FitH">

<p>It appears you don't have a PDF plugin for this browser. No biggie... you can <a href="/pdf/sample.pdf">click here to download the PDF file.</a></p>

</object>

</body>
</html>

I want to use doctype in my page so that other pages work fine. Is there a way to fix first code that contains doctype?

Solution

I would try with an <iframe> element.
If not, maybe transforming it into flash and then embedding the flash.

Also, try <!doctype html> and see what it does, that's the standard doctype for HTML5
