Web Development — Purpose of HTML In everyday web development, what is HTML primarily used for?

Introduction / Context:
HTML (HyperText Markup Language) is a core technology of the World Wide Web. Understanding its role helps you separate concerns among HTML, CSS, and JavaScript when building or maintaining websites and web applications.

Given Data / Assumptions:

• We are focusing on HTML's primary purpose, not optional libraries or integrations.
• HTML is a markup language, not a programming language for math or translation.
• Other tasks like styling and interactivity are handled by CSS and JavaScript, respectively.

Concept / Approach:
HTML provides the structural semantics of a web document: headings, paragraphs, lists, links, images, forms, and semantic sections. It defines the content and its hierarchy so browsers and assistive technologies can parse and present it. Graph plotting, language translation, and equation solving require separate tools, code, or services; they are not the native function of HTML.

Step-by-Step Solution:

Verification / Alternative check:
Open a webpage's source (View Source) to see HTML tags such as html, head, body, h1, p, a, img, and form elements.

Why Other Options Are Wrong:

• Plot complicated graphs: Done via JavaScript libraries or external tools, not by HTML itself.
• Translate one language into another: Requires machine translation services, not HTML.
• Solve equations: Requires computation engines or programming, not markup.

Common Pitfalls:
Assuming HTML alone controls appearance and behavior. HTML structures content; CSS styles it; JavaScript makes it interactive.
