The source provides an overview of how to manage content visibility in web development, beginning with an explanation of HTML comments using the tag, which allows developers to insert notes or temporarily disable code without affecting the browser's rendering. The text then details several methods for hiding content on a webpage, moving beyond comments to explore CSS properties. Specifically, it explains that setting the CSS display property to none completely removes an element from the page flow, while setting the visibility property to hidden makes the element invisible but retains its original space on the page. Finally, the source mentions the straightforward use of the HTML hidden attribute to conceal content and illustrates how these techniques can be applied to hide inline content through inline or internal stylesheets.
