css - how to stretch a background image across the entire window - html

Question

I have a problem with a background image I have when trying to stretch across the entire window. external CSS below:
hr {color:sienna;}
p {margin-left:20px;}
body {background-image:url("mybackground.jpg"); -webkit-background-size: cover; background-repeat: no-repeat; background-size: 70%;}
#font-face /* support for browsers & IE v10 onwards*/
{
font-family:homefont; src: url("font3.ttf");
}
#main
{
position:absolute;
left:450px;
top:30px;
font-family: homefont;
font-size:150px;
line-height:70%;
}
This is what I have (see white space to the right of the image on the browser window):
Can anyone advise me on how to stretch the image across the entire window?
I have tried the suggestions as advised in the comments, however - the image appears to be cut from my knees downward :(. Are there any other suggestions?

Answer 1

Here is an axcellecnt article about your problem on css-tricks
Awesome, Easy, Progressive CSS3 Way:
html {
background: url(images/bg.jpg) no-repeat center center fixed;
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;
}

Answer 2

You can try this
background-size: 100%;
or
background-size:cover

Answer 3

Here you go:
html {
background: url(images/bg.jpg) no-repeat center center fixed;
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;
}
Works in:
Safari 3+
Chrome
IE 9+
Opera 10+ (Opera 9.5 supported background-size but not the keywords)
Firefox 3.6+ (Firefox 4 supports non-vendor prefixed version)

Answer 4

top center;background-size-110%;background-repeat- no-repeat
Please increase the size as you like.

Answer 5

Scale the background image to be as large as possible
You need to use the background-size property with the value cover like below
body {
background-image: url("mybackground.jpg");
background-repeat: no-repeat;
background-size: cover;
}
