Unable to reduce the upload file here to match the size of browse in r shiny

Need to match to the size of browse button. I have tried reducing the height and width but unable to match the size of Browse

column(12,
             tags$style(".form-control { width: 5px; }"),
        
     
             tagAppendAttributes(
               fileInput(
                 inputId = "Data_Upload",
                 label = "",
                 multiple = F,
                 width = "80%",
                 buttonLabel =   div(style = "font-size:10px", "Browse"),
                 placeholder = "Upload File here"
               ),
               style = "height: 10px; font-size: 10%; "
             )
             
        
             
      )
