Error with View component

[Alifarmand]

I am trying to style the View but getting this:
The above error occurred in the <VIEW> component
Uncaught (in promise) Error: Type mismatch

const Overlap = styled.View`
  position: relative;
  height: 16px;
  width: ${props => props.width}%;
  background: blue;
`

I am using this inside a map function to dynamically generate content
