Question

Are

    html, body, div, span, object, iframe, h1, h2, h3, h4, h5, h6, p, 
blockquote, img, strong, dl, dt, dd, 
ol, ul, li, fieldset, form {background:transparent;}

and

body {background:transparent;}

same thing?

Answer 1

They’re the same thing in as much as none of those elements have backgrounds anyway.

They’d only have any effect if they were overriding backgrounds set by previous rules, either earlier in your own stylesheet, or in a user’s custom stylesheet.

I really wouldn’t bother. It’s resetting gone mad.
