Study Notes
Introduction to HTML
- HTML stands for HyperText Markup Language
- It's the standard markup language for creating web pages
- It uses tags to define the structure and content of a web page
- Browsers interpret HTML and render the content into a visual presentation
- HTML is not a programming language, but a markup language
- It describes the content's structure, not its function
Basic Structure of an HTML Document
- Every web page follows a standard structure
- The document starts with a
<!DOCTYPE html>declaration, defining the document type - The root element is the
<html>element - The
<head>section contains metadata about the document, like the title and character set - The
<title>element defines the title shown in the browser tab - The
<body>element contains the visible content of the page
HTML Tags
- Tags enclose content and define its meaning
- Tags are enclosed in angle brackets (
<>) - Types of tags:
-
Opening tag: Starts an element, e.g.,
<p> -
Closing tag: Ends an element, e.g.,
</p> -
Void tags: Some tags, like
<img>, do not require a closing tag
-
Opening tag: Starts an element, e.g.,
- Attributes provide additional information about an element, e.g.,
srcfor an image - Attributes are specified within the opening tag, e.g.,
<img src="image.jpg">
Common HTML Elements
-
<h1>to<h6>: Heading elements for headings of various levels -
<p>: Paragraph element -
<div>: Block-level element used for grouping content -
<span>: Inline element used for styling smaller sections of text -
<a>: Anchor element, for creating links to other pages or locations -
<img>: Image element -
<ul>,<ol>,<li>: Unordered list, ordered list, and list items -
<table>,<tr>,<td>: Table elements for creating tables -
<br>: Line break element -
<hr>: Horizontal rule element
Important Attributes
-
id: Unique identifier for an element -
class: Allows applying styles to multiple elements -
href: Used with<a>tags to specify the link URL -
src: Used with<img>tags to specify the image source -
alt: Used with<img>tags to provide alternative text for the image- Crucial for accessibility and search engines
Semantics
- HTML5 introduced semantic elements to improve the structure and meaning of web pages
- Examples include
<article>,<aside>,<nav>,<header>,<footer> - Semantic elements help search engines and assistive technologies better understand the page's content
Basic Formatting
- HTML supports basic text formatting tags such as
<b/>,<i/>,<u/>,<strike/>,<mark/> - These tags are used for formatting, but are not recommended for styling
- CSS is better suited for styling
HTML Structure and Document Flow
-
Nested Tags: Tags can be nested within each other
-
Document Flow: The order in the HTML document dictates the browser's rendering order, top-to-bottom, left-to-right
-
Block-level vs Inline Elements: Block-level elements take up the full line; inline elements are sized by their content
Conclusion
- HTML is critical for structuring web content
- Understanding HTML tags is vital for creating well-structured and accessible webpages
- Semantic elements, correct tag usage, and understanding document flow are important aspects of web development.
