The htmltools package provides tools for generating, manipulating, and writing HTML from R code. It enables developers to customize user interfaces in Shiny applications and R Markdown documents programmatically without writing raw HTML.
The package serves as a foundation for building HTML components that can be combined and manipulated in flexible ways. It includes tagQuery() for querying and modifying HTML structures, and it supports composing multiple HTML widgets or components into single webpages. This architecture allows other packages to build reusable HTML components that users can customize beyond what component authors originally designed.
