Study Notes
Internal Working of the Web
- The internet is a global network of interconnected computers, enabling communication and information sharing.
- Web servers house websites, and web browsers, like Chrome or Firefox, request and display web pages for users.
- The process begins with a user typing a URL (Uniform Resource Locator) into the browser.
- The browser then sends a request to the web server hosting the corresponding website.
- The web server locates the requested webpage files (usually HTML, CSS, and JavaScript files).
- The server sends these files back to the browser.
- The browser interprets the HTML, a markup language, to display the page structure.
- CSS (Cascading Style Sheets) defines how the page elements are visually presented (colors, fonts, layout).
- JavaScript adds dynamic behavior and interactivity to the webpage (buttons, animations, forms).
- All these actions happen in a sequence of steps and protocols.
HTML (HyperText Markup Language)
- HTML stands for HyperText Markup Language.
- It's the standard markup language for documents designed to be displayed in a web browser.
- It uses tags enclosed in angle brackets
<and>to define elements like headings, paragraphs, images, links, and lists. - These tags structure the content, specifying its meaning and layout. Examples include:
<h1>,<p>,<img>,<a>,<ul>,<ol>,<li>. - HTML documents define the content of a webpage, separating content from its presentation (the style) which is handled by CSS.
- The basic structure of an HTML document includes the
<!DOCTYPE html>declaration, the<html>tag enclosing the entire document, the<head>section containing metadata (e.g., title), and the<body>section containing the visible webpage content. - Each HTML element can have attributes, additional pieces of information within the tags, providing more details about the element. For example, the
hrefattribute in a<a>tag specifies the link's destination. - Cascading Style Sheets (CSS) are used to style HTML elements, defining how they appear. JavaScript is used for dynamic features.
- HTML documents are plain text files that a web browser interprets to display web pages. The format of the file enables a browser to easily read and understand the structure.
Structure of HTML Documents
- HTML documents are composed of elements.
- These elements are defined by tags.
- Tags enclose content and tell the browser how to display it.
- Tags typically come in pairs: an opening tag
<element>and a closing tag</element>. The content goes between the tags. - Basic HTML structure follows a specific format, it uses a root element (
<html>), a head (<head>), and a body (<body>).
Essential HTML Elements
<h1>to<h6>: Define headings of varying importance.<h1>is the most important,<h6>the least.<p>: Defines a paragraph of text.<br>: Inserts a single line break.<a>: Creates a hyperlink. Thehrefattribute specifies the link's destination.<img>: Embeds an image. Thesrcattribute specifies the image's path.<ul>and<ol>: Defines unordered and ordered lists, respectively.- Nested lists can be created by placing
<ul>or<ol>elements inside others.
- Nested lists can be created by placing
<li>: Defines a list item.<div>and<span>: Generic container elements used for structuring content and styling.<div>is for larger sections,<span>for smaller parts of a text.
<header>,<nav>,<article>,<aside>,<footer>: Structural elements representing different sections of a web page. These elements aid in structuring the webpage.
Attributes
- Attributes provide additional information about HTML elements. They are placed within the opening tag.
- Common attributes include
href,src,id,class, andtitle.idis unique to a certain HTML element.classis a group or name for a set of elements.
- Attributes often dictate the behavior or appearance of the corresponding element.
Semantic HTML
- Semantic HTML uses elements with meaningful names to describe the content of a page.
- Examples include
<header>,<nav>,<article>,<aside>, and<footer>.
- Examples include
- This type of HTML improves accessibility and SEO.
Key Concepts
- Elements use tags to define content and structure, such as
<p>for paragraphs. - Attributes modify elements; for example,
hrefin<a>tags specify links. - HTML structure uses a hierarchy to organize content (e.g., headings, paragraphs, lists).
- Semantic HTML defines elements meaningfully to improve both accessibility and search engine optimization (SEO).
- HTML is the foundation of web pages and determines how content is presented to users.
