I have found a very well-design shiny app on shinyapps.io website but I am not sure how to access its R code or say the github directory for its code. I find it very instructive if we could have access to its code. Anyways, in the worst case, can someone help me to know how can I have nice sidebarPanels and mainPanels like this website? I know some CSS is involved but I am new to CSS and not sure how to get some neat design like that in shiny.
I don't exactly know how the app looked (the app is down) but I guess you should take a look at "shinydashboard". That gives you a very nice side and main panels.
