css - Shiny - Changing size, colour and font of text (boxes) -


this must simple question, haven't managed find script or advice regarding changing size, font , colour of text in shinydashboard boxes. example, want make box display 14px arial grey text:

  box(width = 4, title = "sample", "this test")

i imagine requires css, there way can achieve using built-in functions shiny?

many thanks.

you need change box's css work. pass css directly in ui, using tablehtml::make_css. function box creates html class called "box" can use change box's css:

library(shiny) library(tablehtml)  ui <- fluidpage(  tags$style(make_css(list('.box',                            c('font-size', 'font-family', 'color'),                            c('14px', 'arial', 'red')))),  box(width = 4, title = "sample", "this test") )  server <- function(input, output) {}  shinyapp(ui = ui, server = server)

output:

i made text red can tell difference black easily. can replace grey or whichever colour want.

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
