standard "metadata" coming at the end of whatever I html-export. I'm sure I can change this, right?

Also, does anyone have a tutorial (or in-depth discussion) of org mode CSS lore for html export? One issue was good indenting when headings start getting deep -- then keeping sundry content under a heading to also go along with that indentation. Typically, whenever I just do an Inspect in Chrome and start fooling around, I fix one thing and break something else. Very mysterious. . . .
