Study Notes
Introduction to HTML
- HTML stands for HyperText Markup Language.
- It's the standard markup language for creating web pages and web applications.
- HTML describes the structure of a webpage semantically.
- HTML elements are represented by tags, enclosed in angle brackets
<and>. - Tags typically come in pairs: an opening tag and a closing tag.
- The content between the tags defines the element's meaning.
- HTML documents are interpreted by web browsers, which render the content into a visual presentation.
Basic HTML Structure
- Every HTML document begins with a
<!DOCTYPE html>declaration, specifying the document type. - The root element is the
<html>element, containing the entire content of the page. - Inside
<html>, there are two main sections:<head>and<body>. - The
<head>section contains meta-information about the document, such as the title, character encoding, and links to external resources. Thetitleelement is crucial for the browser's title bar and search engine indexing. - The
<body>section contains the visible content of the page, including text, images, links, and other elements.
HTML Elements
- HTML elements are fundamental building blocks.
- They define the structure and content of a webpage.
- Common elements include headings (
<h1>to<h6>), paragraphs (<p>), lists (<ul>,<ol>,<li>), images (<img>), links (<a>), and more. - Each element has specific attributes, which provide additional information and control its behavior. For example, the
<img>tag uses attributes likesrc(source of the image) andalt(alternative text for the image). - Attributes are written within the opening tag, in the format
attribute="value".
HTML Tags
- Tags are used to enclose HTML elements.
- Opening tags typically have the form
<element>. - Closing tags typically have the form
</element>. - Some elements are empty elements (e.g.,
<img>,<br>), meaning they don't have a closing tag. - Nested elements are common, where one element appears inside another, creating a hierarchical structure.
HTML Attributes
- Attributes provide additional information about HTML elements.
- Attributes are placed within the opening tag.
- Common attributes include
id,class,href,src,alt,title, and more. - Attributes specify specific properties of an element, such as its value, destination, width, height, and so forth.
- Attributes are crucial for customizing element behavior and aiding web accessibility and search engine optimizations.
HTML Semantic Elements
- HTML5 introduced new semantic elements, which describe the purpose or meaning of the content more explicitly.
- These include
<article>,<aside>,<nav>,<header>,<footer>,<section>,<main>,<figure>,<figcaption>. - Semantic elements improve document structure, enhance accessibility, and enhance search engine optimization (SEO). They allow for better organization and presentation of web content.
Basic HTML Example
- A simple HTML page example showcasing the structure:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>My First Webpage</title>
</head>
<body>
<h1>Hello, World!</h1>
<p>This is a paragraph.</p>
</body>
</html>
- The provided example is a very basic HTML page, missing the crucial
<img>element tag as used in a previous example, and now includes a<h1>and<p>tag example.
