268. At least one cloth should be placed on the altar out of reverence for the celebration of the memorial of the Lord and the banquet that gives us His body and blood. The shape, size, and decoration of the altar cloth should be in keeping with the design of the altar.
269. Candles are to be used at every liturgical service as a sign of reverence and festiveness. The candlesticks are to be placed either on or around the altar in a way suited to the design of the altar and the sanctuary. Everything is to be well balanced and must not interfere with the faithful's clear view of what goes on at the altar or is placed on it.
270. There is also to be cross, clearly visible to the congregation, either on the altar or near it.
