Can't get rid of space at top of web page...

[Mapper99]

I have a very simple webpage using css. For some odd reason there is about a 20px space at the top of my page. I have no idea where this is coming from! Any ideas?

Here is the page that is causing me grief:

Thanks in advance,

body {
  text-align:center;
  font-family: Georgia, Serif;
  background: #000000;
 margin:0px;
}

i think this can help u

order is important in css
in some of the styles you set

margin-top:0;
margin:5px;

result margin-top:5px; in other styles you correctly zero the top margin

margin:5px;
margin-top:0;

a group of applied 5px will soon add to the 'missing' amount

Do not put px on a zero value. It is not supported. Put 0 instead of 0px.

make sure there are no in your code that will create a space if in the wrong place

also make sure that the div or table you have as your header, has no margin-top pushing it down.

I followed most of the advice I found on here, and finally what worked for me was the body-top:0; I had originally used just the standard header or wrapper or whatever:0px; so hats off to you and kudos good sir.
Enjoy.

you need to set a negative margin rtfm -20px etc easy peasy

check the margin-top and padding-top of ur each style class (especially outer)... and check the heights and min-height of each div tag... google chrome inspect functionality may be helpful to solve this...
