# Procedural Ruby ## Transitioning Back to Ruby Congratulations on completing the HTML and CSS introduction! The upcoming Procedural Ruby section will focus our attention back to Ruby, but it will also leverage our understanding of the HTML document structure and CSS selectors (ID, class, and type) during the ruby 'web scraping' lessons (programmatically extract data from web pages). You will also use your current HTML and CSS knowledge during the more advanced HTML and CSS lessons at the end of the Rack section. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://certil-remy.gitbook.io/learn/ruby.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
