Which web standard is critical for structuring content on the internet?

HTML, or HyperText Markup Language, is crucial for structuring content on the internet because it provides the foundational building blocks for web pages. HTML allows developers to define elements on a web page such as headings, paragraphs, links, images, and lists. By using tags, HTML outlines the semantic structure of a webpage, enabling browsers to interpret and display the content correctly.

While XML is a markup language that focuses on storing and transporting data, it does not inherently dictate how that data should be presented in a web browser. JSON is primarily a format for data interchange, not for displaying content on web pages. CSS, or Cascading Style Sheets, is essential for styling the appearance of HTML content but does not contribute to the structural organization of that content. Therefore, HTML is the core standard needed for objecting and presenting information effectively on the web.
