This example displays the text "Hola HTML" prominently in the center of the page, using a large font size of 13em. The page is a bare minimum HTML document that includes a `<head>` section with a `<style>` block for centering the body text. It demonstrates a basic setup for an HTML page, containing only a `<!DOCTYPE html>` declaration, an `<html>` element, and a `<body>` with the static text. The styling is applied directly through the CSS `body` selector, and no JavaScript or external libraries are used.
