This chapter has incorporated quite a pile of tools into your Shiny toolbox. You learned how to use custom HTML straight from a minimal ui.R UI setup and how to build the whole thing from scratch using HTML and CSS.

In the next chapter, you are going to learn more about building a UI with Shiny. Shiny includes a lot of different layout functions, which will all be described, and we will also look at making nice tables, using progress bars, and modals, as well as making your UI reactive.
