HTML is the backbone of a webpage. It organizes text, images, links, and other elements so browsers know what to show and where.
CSS handles styling, JavaScript handles behavior, and servers handle data storage.
The <h1> tag defines the main heading. The <head> contains metadata, <header> is a section container, and <title> sets the page title in the browser tab.
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Test Page</title> </head> <body> <h1>Welcome</h1> <p>This is a <strong>simple</strong> page.</p> </body> </html>
The <h1> tag creates a large heading. The <p> tag creates a paragraph. The <strong> tag makes text bold. The code is valid and will render as described.
The <nav> element is used to group navigation links. <section> is for thematic grouping, <div> is a generic container, and <article> is for self-contained content.
The alt attribute gives a text description of an image for screen readers and when images fail to load. title shows a tooltip, src is the image source URL, and href is for links.
