Why sometimes hr() has a bad behavior in Shiny? I use the same code but the lines are different and sometimes one of then does not appears?
The code used:
column(12,
hr(style = "border-top: 1px solid #000000;"),
h3("Input de dados", style = "align:center;text-align:center"),
hr(style = "border-top: 1px solid #000000;"),
headerPanel(""),
),
