lipgloss

---

Lipgloss applies cosmetic styling to terminal output—transforming plain text into beautifully formatted, bordered, and colored displays. Like its namesake adds shine and color to lips, this library adds visual polish to command-line interfaces, making them more engaging and readable.

1. Add the dependency to your shard.yml:

     .padding(1, 2)
   
   puts style.render("Hello")
