My Character is floating slightly above my box colliders for my Tilemap

Hi I’m new to Unitiy’s TileMap system but I’ve run into a weird problem vie to set up my box colliders for my player and the ground but the player seems to be floating above the ground I tested it again with a plank box sprite and the same thing is happening I’m not sure why this is happening I’ve been looking everywhere for a solution but nothing has turned up can anyone help me?182191-problem.png

if your using tile maps put the ground tiles on a seperate layer and use a tile map collider2d on the ground tiles
