we are allowing user to upload an image once user click on car....
Once user Upload the image , we are displaying the user uploaded image on top of the car & displaying text "Edit" outside the container....
Requirement :
But I want to display that text in a same position as of the image....
if car position is left : 1px
I want the text position also should be left : 1px
