not sure of the question but you will need to make either a seprate file and link it to the html page in the header section ( this is the best way imo so I want mention the others )
just figure out what you want if you want you background to be a certain image then in the css file you will create it that way like:
body{
background-image:url("bkgrdimg.jpeg");
}
if you want all the text to be blue and 12 font then just add
color:blue;
font-size: 12pt;
but If you already have the style inside the html just move it to the css file like if you have :
< table witdh ="100%" align ="center" border="4">
go to the css file and make it something like
.table1{
width:100%;
align:center;
border:4;
}
then go to the html page and change it to
<table id="table1">
hope this somewhat clears it up
