Modify the appearance of selectInput and numericInput controls

Looking to update the appearance of my Shiny UI elements to better match the overall website design.

Specifically, I want to eliminate the rounded edges on the selectInput boxes for a cleaner look like this:

Additionally, I'm interested in creating a sleek numericInput box that resembles the following:

https://i.sstatic.net/f62n3.png

Wondering if there is a straightforward method to achieve this. While proficient in R, my knowledge of css and html is limited. Considering flanking a numericInput with actionButton elements to serve as plus/minus keys, but unsure how to style them accordingly.

Are there specific style attributes or javascript libraries that can be utilized to accomplish either of these goals?

Answer №1

After some feedback from ash, it was suggested to eliminate the rounding on the first question by adjusting the border-radius to 0px:

shinyApp(
  ui=fluidPage(
    tags$head(
      tags$style(".selectize-input {border-radius:0px}"),
      tags$style(".selectize-input.dropdown-active {border-radius:0px}"),
      tags$style(".selectize-dropdown {border-radius:0px}")),
    selectInput("select", "Select", 1:3)),
  server=function(input, output){})
