HTML Basics 뼈대

HTML (HyperText Markup Language) is the standard markup language for creating web pages. It provides the structure and content of a website. Think of it as the skeleton upon which everything else is built.

Core Concepts

• Tags: HTML elements are defined by tags. Most tags have an opening and closing tag (e.g., <p> and </p>), while some are self-closing (e.g., <br>).
• Elements: An HTML element consists of an opening tag, content, and a closing tag.
• Attributes: Attributes provide additional information about HTML elements. They are specified in the opening tag (e.g., <a href="https://www.example.com">).
• Structure: A basic HTML document has a specific structure, starting with <!DOCTYPE html>, followed by <html>, <head>, and <body> elements.

Essential HTML Tags

• <!DOCTYPE html>: Defines the document type and version of HTML being used.
• <html>: The root element of an HTML page.
• <head>: Contains meta-information about the HTML document, such as the title, character set, and linked stylesheets.
• <title>: Specifies a title for the HTML page (which is shown in the browser's title bar or tab).
• <body>: Contains the visible page content.
• <h1> to <h6>: Define headings of different levels.
• <p>: Defines a paragraph.
• <a>: Defines a hyperlink. Use the href attribute to specify the link's destination.
• <img>: Embeds an image. Use the src attribute to specify the image source.
• <ul>, <ol>, and <li>: Define unordered lists, ordered lists, and list items, respectively.
• <div>: Defines a division or a section in an HTML document.
• <span>: An inline container used to mark up a part of a text, or a part of a document.
• <table>, <tr>, <th>, and <td>: Defines a table, table row, table header, and table data cell, respectively.
• <form>, <input>, <textarea>, <button>: Used for creating interactive forms for user input.

Basic HTML Structure

A standard HTML document follows this basic structure:

   
    <!-- Define the document type -->
    <!DOCTYPE html>
    <html>
     <head>
      <meta charset="UTF-8">
      <title>Page Title</title>
     </head>
     <body>
      <h1>My First Heading</h1>
      <p>My first paragraph.</p>
     </body>
    </html>
   
  

Semantic HTML

Semantic HTML uses tags to convey the meaning of the content. This helps search engines and assistive technologies understand the structure and content of the webpage. Examples include:

• <article>: Represents a self-contained composition in a document, page, application, or site.
• <aside>: Represents a section of a page that is tangentially related to the content around it.
• <nav>: Defines a set of navigation links.
• <header>: Represents a container for introductory content or a set of navigational links.
• <footer>: Defines a footer for a document or section.
• <section>: Defines a section in a document.

Importance of HTML

• Foundation of the Web: HTML is the backbone of all web pages, providing the structure and content.
• SEO: Proper HTML structure improves search engine optimization, making it easier for search engines to understand and index your content.
• Accessibility: Semantic HTML improves accessibility for users with disabilities, making it easier for assistive technologies to interpret and present content.
• Compatibility: Well-structured HTML ensures compatibility across different browsers and devices.
