14 month old and timeout?

My daughter very strong willed and no means nothing to her. When I say no and take something away from her or take her away from something she loses her mind, screaming, crying, tears and *my fav* laying on the floor... I was thinking bout timeout? Putting her in the pack and play for a minute? I feel like she might be young but then again I have to get a handle on her behavior. Any ideas?
