If you are unfamiliar with HTML tag attributes, you can look them up in one of the many free online HTML resources such as w3schools. In general, any HTML tag attribute can be set as an argument in any Shiny tag function. You can create this effect with align = "center", as in h6("Episode IV", align = "center"). If George Lucas had a first app, it might look like this. ui <- fluidPage ( titlePanel ( "My Shiny App" ), sidebarLayout ( sidebarPanel (), mainPanel ( h1 ( "First level title" ), h2 ( "Second level title" ), h3 ( "Third level title" ), h4 ( "Fourth level title" ), h5 ( "Fifth level title" ), h6 ( "Sixth level title" ) ) ) ) Remember to relaunch a Shiny app you may run runApp("App-1"), click the Run App button, or use your keyboard shortcuts. Update your ui.R to match the script and then relaunch your app. The new script below uses all six levels of headers. You can place multiple elements in the same panel if you separate them with a comma. The text will appear in the corresponding panel of your web page.
If you run the command at the command line, you’ll notice that it produces HTML code. Give it the text you want to see in the headerįor example, you can create a first level header that says “My title” with h1("My title"). Select a header function (e.g., h1 or h5) Edit the script to match the one below: library ( shiny ) # Define UI - ui Īn in-line division of text with a uniform styleĭirectly passes a character string as HTML code We’ll use the App-1 app you made in Lesson 1. You will learn how to lay out the user interface and then add text, images, and other HTML elements to your Shiny app.
This lesson will show you how to build a user interface for your app. Now that you understand the structure of a Shiny app, it’s time to build your first app from scratch.
