Motives based on Hodge cycles vs algebraic cycles

I am not a specialist of motives. I am afraid my questions are rather naive. We have the category of (pure) motives based on Hodge cycles by Deligne. … In his articles with Milne, morphisms between motives are defined using absolute Hodge cycles. On the the hand we have the (triangulated) category of (mixed) motives based on Voevodsky. …

Elementary questions on motives

Do we have a theory on the category of objects consisting of motives and algebraic varieties? … ③Motives are direct factors of cohomology, but I do not find any definition of motives using cohomology. I know their definition using hodge cycles and algebraic cycles. …
