Gradient full scale background CSS - css

Question

Full page CSS3 Gradient Backgrounds:
Alright so I am trying to make my background be a gradient that is always 100% width and height, and it works, except for the fact that nothing will show up on top of it. Here is the code I currently have.
CSS:
<style type="text/css" media="screen">
#bodyBg{
background:rgb(79,143,249) no-repeat center center fixed; /* Old browsers */
background: -moz-radial-gradient(center, ellipse cover, rgba(164,197,252,1) 1%, rgba(79,143,249,1) 100%); /* FF3.6+ */
background: -webkit-gradient(radial, center center, 0px, center center, 100%, color-stop(1%,rgba(164,197,252,1)), color-stop(100%,rgba(79,143,249,1))); /* Chrome,Safari4+ */
background: -webkit-radial-gradient(center, ellipse cover, rgba(164,197,252,1) 1%,rgba(79,143,249,1) 100%); /* Chrome10+,Safari5.1+ */
background: -o-radial-gradient(center, ellipse cover, rgba(164,197,252,1) 1%,rgba(79,143,249,1) 100%); /* Opera 12+ */
background: -ms-radial-gradient(center, ellipse cover, rgba(164,197,252,1) 1%,rgba(79,143,249,1) 100%); /* IE10+ */
background: radial-gradient(ellipse at center, rgba(164,197,252,1) 1%,rgba(79,143,249,1) 100%); /* W3C */
filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#a4c5fc', endColorstr='#4f8ff9',GradientType=1 ); /* IE6-9 fallback on horizontal gradient */
min-height: 100%;
min-width: 1024px;
width: 100%;
height: auto;
position: fixed;
top: 0;
left: 0;
z-index:0;
}
#media screen and (max-width: 1024px) { /* Specific to this particular image */
#bodyBg {
left: 50%;
margin-left: -512px; /* 50% */
}
#body-404 {
position: relative;
margin: 50px auto;
width:880px;
text-align:center;
color:white;
font-family: "Helvetica Neue", "URW Palladio L", Arial, Helvetica, "Palatino Linotype";
z-index:99;
}
</style>
HTML:
<div id="body-404">

Answer 1

It's generally considered poor practice to have empty elements like your #bodyBg. Just put the background gradient on the html (or body) element and get rid of the useless div:
http://jsfiddle.net/2yVRA/1/
html {
background:rgb(79,143,249) no-repeat center center fixed; /* Old browsers */
background: -moz-radial-gradient(center, ellipse cover, rgba(164,197,252,1) 1%, rgba(79,143,249,1) 100%); /* FF3.6+ */
background: -webkit-gradient(radial, center center, 0px, center center, 100%, color-stop(1%,rgba(164,197,252,1)), color-stop(100%,rgba(79,143,249,1))); /* Chrome,Safari4+ */
background: -webkit-radial-gradient(center, ellipse cover, rgba(164,197,252,1) 1%,rgba(79,143,249,1) 100%); /* Chrome10+,Safari5.1+ */
background: -o-radial-gradient(center, ellipse cover, rgba(164,197,252,1) 1%,rgba(79,143,249,1) 100%); /* Opera 12+ */
background: -ms-radial-gradient(center, ellipse cover, rgba(164,197,252,1) 1%,rgba(79,143,249,1) 100%); /* IE10+ */
background: radial-gradient(ellipse at center, rgba(164,197,252,1) 1%,rgba(79,143,249,1) 100%); /* W3C */
filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#a4c5fc', endColorstr='#4f8ff9',GradientType=1 ); /* IE6-9 fallback on horizontal gradient */
min-height: 100%;
}
#media screen and (max-width: 1024px) { /* Specific to this particular image */
body-404 {
position: relative;
margin: 50px auto;
width:880px;
text-align:center;
color:white;
font-family: "Helvetica Neue", "URW Palladio L", Arial, Helvetica, "Palatino Linotype";
z-index:99;
}

Answer 2

Use the background-image CSS property instead of using the image tag. I've made a quick jsfiddle to show what I mean. I know it's not exactly what you're going for but you should be able to change it for your use pretty quickly. If not, let me know.
