Hi,
I use the following code to center text in a well panel in several shiny apps:
tags$head(tags$style(HTML("
#auc {
text-align: center;
#texto {
text-align: center;
}
}"))),
but the script file in RStudio 1.2.5019 doesn't run (hitting ctrl-enter), only when I rename the whole Script file to "app.R" and click on "run App". If I remove the above snippet, then it runs, but the text is no longer centered in the well panel. This does not happen with RStudio 1.2.1335.
I use Windows 10 home single language, version 1903. Please help.
Thanks.
Luis
