Is HTML and CSS considered a programming language?

As an expert in the field of web development, I can provide some insights into the nature of HTML and CSS in relation to programming languages. HTML, which stands for Hypertext Markup Language, is not a programming language but a markup language. It is used to structure content on the web, defining elements such as paragraphs, headings, and links. HTML tells the web browser how to display the content. CSS, which stands for Cascading Style Sheets, is also not a programming language; it is a stylesheet language used to describe the presentation of a document written in HTML. CSS describes how elements should be rendered on the screen, including layout, colors, and fonts. While both HTML and CSS are essential for web development, they do not have the same capabilities as programming languages. They do not support programming logic such as loops, conditional statements, or functions, which are common in programming languages like JavaScript, Python, or SQL. To summarize, HTML and CSS are not considered programming languages because they lack the computational abilities and logic structures inherent in programming languages. They are used for structuring and styling web content, not for creating programs that can solve complex problems.

SQL, for example, is declarative but is also a proper programming language because it is T-C.) Of course, the same isn't true of a markup language like HTML or CSS. In fact, there are whole classes of problem that these languages simply can't solve.
