I'm sure you have a basic understanding of what kitchen sinks are, but do you really know why developers are interested in them? Hint: it's not because of food.
The first time I came across the phrase "to put together a kitchen sink in HTML5," I had to look up its meaning. Let me save you the effort. This phrase means creating a comprehensive display of what a website can offer. A kitchen sink includes native HTML and other elements of the website, built with a combination of HTML, CSS, and JavaScript. Examples include various formatted text options such as bold, italic, underline, font color, as well as alignment, buttons, dropdowns, images, tables, images, forms and more.

In the context of Bootstrap, a kitchen sink refers to a documentation section that showcases examples of all the available classes, components, and features that Bootstrap provides - check out Bootstrap Cheatsheet.
A kitchen sink serves as a comprehensive reference or visual guide for developers. Instead of navigating through the entire documentation to find specific classes or components, they can refer to the kitchen sink page to quickly see examples and understand how different elements can be styled and configured.
