How to i get the background to be HD, currently when i upload a HD background it gets blurred out and looks ugly.

[size=200][color=#3498db][b]Step 1. make sure the resolution of the background is good. Step 2. go to ADMIN>Design>Developer Code> CSS Code Copy & Paste this: [/b][/color][/size] [quote][size=200][color=#3498db][b]body {[/b][/color][/size][/quote] [quote][color=#3498db][size=200][b]background-image: url("yourimageurl");[/b][/size][/color][/quote] [quote][size=200][color=#3498db][b]background-repeat: no-repeat; }[/b][/color][/size][/quote] [size=200][color=#3498db][b]After that you can upload an image to imgur or something and paste the link inside the quotes then save your changes and see the results, also make sure to delete any uploaded Image cause it will overwrite the code and act as if its not there.[/b][/color][/size]
