Topic: Why <! DOCTYPE html> breaks

&lt;head&gt;
&lt;style&gt;
.login {
background: url (../img/bg.jpg) no-repeat center center fixed;
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;
height: 100 %;
overflow: hidden;
}
&lt;/style&gt;
&lt;/head&gt; &lt;body class = "login"&gt;
&lt;/body&gt;

If I add in the document beginning &lt;! DOCTYPE html&gt; on mobile devices  (with a size 1100600) it is displayed in 100 % the size, and a lot of the empty place below turns out. How to correct? sad
If I do not add &lt;! DOCTYPE html&gt;, all is normal, the image part completely covers visible area.
