What are css align & cellspacing comands?

[ilya Kraft]

Helo,
I'm working on my site now, tried to validate it and got couple of errors like this

Line 135, Column 50: The align attribute on the table element is obsolete. Use CSS instead.
<table id="footer" align="center" cellspacing="0">

Line 135, Column 50: The cellspacing attribute on the table element is obsolete. Use CSS instead.
<table id="footer" align="center" cellspacing="0">

What do i put in css for align and cellspacing?

I've also got this error:

Line 129, Column 208: The name attribute on the img element is obsolete. Use the id attribute instead.
…/logo1.png" alt="Logo" name="Home" width="372" height="110" border="0"></a></p>

Line 129, Column 208: The border attribute is obsolete. Consider specifying img { border: 0; } in CSS instead.
…/logo1.png" alt="Logo" name="Home" width="372" height="110" border="0"></a></p>

and i have no idea about what it asks me to do(this is a rollover image)

#header {
	background-image:url(images/header.png); 
	width:924px;
	height:30px;
	border:0px;
	padding:0px;
        ?????????
        ?????????
}

remove these deprecated attributes and replace them by CSS if necessary.
