unwanted vertical scrollbars

Question

I have unwanted vertical scrollbars in all browsers even if the content does not occupy the entire page. Improvement and changes to css are welcome!

 <div id="header">
 </div>
 <div id="container">
     <div id="title"><h2>Admin</h2></div>
     <div id="content">
         <div class="login">
             <div>&nbsp</div>
                 <form method="post" action="/admin/index.php">
                  <p><input type="text" name="username" value="" placeholder="Username"></p>
                  <p><input type="password" name="password" value="" placeholder="Password"></p>
                  <p><input type="submit" name="login" class="button" value="Send"></p>
                  <p class="error">&nbsp;</p>
                 </form>
            </div>

Answer 1

simplest solution without editing ur css 


Remove height:100%; from body 


html, body {
margin: 0;
padding: 0;
font-family: Arial, Helvetica, sans-serif;
font-size: 85%;
color: #333399;
}

Answer 2

I saw the scroll bars, but only when I play with the window size. I think since you are using % for height, you can eliminate the #container min-height:80%; tag as this will eliminate the overflow/scrollbar issue.

When you use the header at 15% and the footer at 5% the remaining 80% is automatically filled with the container.

Another option could be to use the position:relative tag in the header and add a top:15%; to dial in the header positon. Or you could offer up a min-height:10%; and max-height:15%; to dial in the header size in total.

If you want the footer to always remain at the bottom, you can set position:relative bottom:5%; within it's css

Answer 3

Take the minimum height out of your CSS elements. Here is an example. And here is what you want to do to your CSS code:

     #container {
        margin-left:auto;
        margin-right:auto;
        width:70%;
      }

This should fix any problem with that vertical scroll bar.
