HTML
The Hypertext Markup Language, or HTML, is a text-based markup language for structuring electronic documents such as texts with hyperlinks, images and other content.
HTML documents are the basis of the World Wide Web and are displayed by web browsers. In addition to the content displayed by the browser, HTML files can contain additional details in the form of meta-information, e.g. about the languages used in the text, the author or the summarized content of the text. HTML is therefore the basis of an Internet page.
That means with HTML you can determine which texts and contents should be displayed on an internet page.

CSS
Cascading Style Sheets (CSS) is a language that defines how documents are presented to the user. A document is a collection of information (text, images...), which is structured with a markup language (HTML). The markup language specifies that a text should be presented, for example, as a heading or as a link. However, it is not specified how a heading or a link should be displayed. This is the task of CSS.
You can imagine that HTML is the basic structure of a website and CSS defines the style of presentation. So you can use CSS to adjust e.g. the font, size, layout, color etc. of a website.
Bootstrap
Bootstrap is a free and open-source CSS framework directed at responsive, mobile-first front-end web development. It contains CSS- and (optionally) JavaScript-based design templates for typography, forms, buttons, navigation, and other interface components.
JavaScript
JavaScript, often abbreviated JS, is a programming language that is one of the core technologies of the World Wide Web, alongside HTML and CSS. Over 97% of websites use JavaScript on the client side for web page behavior, often incorporating third-party libraries. All major web browsers have a dedicated JavaScript engine to execute the code on the user's device.
JavaScript is a high-level, often just-in-time compiled, multi-paradigm language. It conforms to the ECMAScript specification, and has dynamic typing, prototype-based object-orientation, and first-class functions. It supports event-driven, functional, and imperative programming styles. It has application programming interfaces (APIs) for working with text, dates, regular expressions, standard data structures, and the Document Object Model (DOM).
