applying a margin to the cover div

I am currently working on a #cover element with the following CSS styling:

#cover {
    background-color: #FFFFFF;
    height: 100%;
    opacity: 0.4;
    position: fixed;
    width: 100%;
    z-index: 9000;
}

The goal is to have it cover the entire visible page, but when I scroll down, I notice that there is an added margin of 8 pixels at the top and left.

Even after trying margin:-8 -8 8 8;, the issue persists. Why is that? And how can this be fixed?

Here is a DEMO fiddle illustrating the problem.

Answer №2

An easy fix for a common problem.

Simply add this to your CSS:

* /*Remove all default margin and padding*/
{
    margin: 0;
    padding: 0;
}
html, body /*ensures it works when specifying 100% height on an element*/
{
    height: 100%;
}

By the way, be sure to use units (px/%) for margins/paddings other than 0.

Here's a Fiddle for reference.

Also, you can achieve the desired result without using the fixed position. Take a look at this fiddle for more information.
