Hello I am in Art Class Right Now. I need to know what juxtaposition is. It is a type of art

Juxtaposition is the act of positioning two or more things side by side or close together as per the Merriam Webster dictionary. In visual arts, juxtaposition entails making the ordinary look extraordinary and represents one of the essential techniques in the Surrealism art movement.

Explanation:

well seeing i am an artist and i actually did a self portrait; i will describe how i painted it.   i used acrylic on a stretch canvas about 4 feet wide by 6 feet tall. i painted myself smiling in a soft pink long dress, white tile floor sitting on a white couch with a table behind and a vase of gorgeous flowers.   i also had a round white hat with a soft pink ribbon through it laying on the floor and on the table behind me was a lit candle. i kept it simple but soft and romantic.
