Most of the one's I have run across do not have an overflow. Mainly used for disposal, dumping out drinks, etc, not for washing so overflow not really an issue. Also, most are stainless which do not lend themselves to an overflow drain.
Yes.
CSS overflow is used by programmers to still use a box when the content inside is too large for it. Scroll bars and hidden content are commonly used to help this problem.
You should use black pipe -- Galv. pipe will flake off inside of pipe

A furnace vent is a metal pipe that extends from the furnace to the outside of the house. It is usually located on the side or roof of the house and is used to expel exhaust gases from the furnace.
In my experience, I would say no. Several reasons can prevent the overflow from working. Since the overflow of the sink is rarely used it has a tendency to be blocked at the lower portion where the sink joins the drain pipe. During normal use and over years the holes in the sink drain at the point where the overflow and drain pipe meets has a tendency to clog making the overflow drain slowly. You can notice this when your sink drains with a "gulping" sound. You can test the overflow drain and see how obstructed it is, but do it slowly and do not turn on the faucets on full.
Use only black pipe
Water main coming into house usually 3/4" K copper pipe. Depending on local plumbing code, fitting usually is flared or soldered.
The size of the water pipe from the meter to the house should be determined based on the water flow rate needed for the house. It is recommended to consult with a professional plumber to determine the appropriate size of the water pipe for optimal water flow and pressure.
Get rid of the entire copper pipe and fit 3/4 PEX from the street main into the house. Cheap and reliable.
Check pipe size for hot water or if galvanized pipe used, pipe could be clogged inside with rust and scale.
