WordPress Custom Theme editing problem

Hi, yesterday I made a custom theme for WordPress after linking it to my site by following these instructions:

This is the blog: https://www.thewebsiteofdaniel.net/blog

It’s all set up fine and I can change the font and the background colour etc. by editing this CSS file:

/*
Theme Name: DeathMonkey
Theme URI: The Website of Daniel
Description: My custom WordPress theme
Version: 1.0
Author: Daniel Batty
Author URI: https://www.thewebsiteofdaniel.net

*/

body{
	margin: 0;
	font-family: Calibri; Arial
	font-size: 12px;
	font-color: #ffffff
	text-align: center;
	vertical-align: top;
	background: url("images/bg.png")
	color: #ffffff;
}

a:link, a:visited{
	text-decoration: underline;
	color: #336699;
}

a:hover{
	text-decoration: none;
}

#wrapper{
	margin: 0 auto 0 auto;
	width: 750px;
	text-align: left;
}

#header{
	float: left;
	width: 750px;
}

#box{
	float: left;
	width: 500px;
}

.sidebar{
	float: left;
	width: 240px;
	background: #eeeeee;
	margin: 0 0 0 10px;
	display: inline;
}

#footer{
	clear: both;
	float: left;
	width: 750px;
}

.comments-template{
	margin: 10px 0 0;
	border-top: 1px solid #ccc;
	padding: 10px 0 0;
}

.comments-template ol{
	margin: 0;
	padding: 0 0 15px;
	list-style: none;
}

.comments-template ol li{
	margin: 10px 0 0;
	line-height: 18px;
	padding: 0 0 10px;
	border-bottom: 1px solid #ccc;
}

.comments-template h2, .comments-template h3{
	font-family: Georgia, Sans-serif;
	font-size: 16px;
}

.commentmetadata{
	font-size: 12px;
}

.comments-template p.nocomments{
	padding: 0;
}

.comments-template textarea{
	font-family: Arial, Helvetica, Georgia, Sans-serif;
	font-size: 12px;
}

I want to set a picture (1280×1024) as my background (the same one as my homepage) but it just shows up with a white screen…Likewise, I tried adding in “font-color: #NUMBER” to set the font color and yet again, nothing changes… any ideas?
