Study Notes

Document Type

Every HTML document must start with a <DOCTYPE> tag, specifying the markup standard (e.g. HTML5).
The DOCTYPE tag is essential, as it tells the browser which standard to use when parsing the code.
HTML5 simplifies document type declaration, only requiring <!DOCTYPE html>.
Without a valid DOCTYPE, the legacy browser uses "quirks mode" rendering the page potentially incorrectly.

HTML5 Page Structure

The <html> element encloses the entirety of an HTML5 web page.
The <head> element contains metadata about the page, such as the title and links to stylesheets.
The <body> encloses the visible content of the web page.

Page Layout and Section Elements

Common web page layouts usually involve a heading, navigation, content, and footer.
HTML5 provides semantic section elements (<header>, <nav>, <main>, <aside>, <footer>) for better structural organization.
The <div> element, while still valid in HTML5, is often used for specific styling needs or for dividing content into sub-sections.

White Space in HTML

HTML typically ignores extra white space between elements, meaning spaces, tabs, and line breaks are treated the same.
This allows for more concise coding and flexibility but consistency in using white space is recommended for readability.

Comments in HTML

Comments can be added using .
These comments are ignored by the browser but help explain the code and are visible to anyone who views the source code.

Main HTML5 Elements

HTML5 provides elements for defining content like headings (<h1> to <h6>), paragraphs (), and horizontal rules (<hr>).
Section headings are crucial for site visitors and help with page readability.
Text level elements like  (bold),  (italic), <a> (link), <img> (image) are used to style and link content.

Absolute Addresses

Absolute addresses specify the location of a file using a URL (Uniform Resource Locator), using the format protocol://host/filename.
The protocol (http, https) indicates the network protocol used to download the file.
The host specifies the web server (e.g., www.google.com) and the filename specifies the file path and name on the server.

Character Sets

Computers represent characters using numerical codes defined by character sets.
The American Standard Code for Information Interchange (ASCII) was the original standard for English characters.
As computing became global, character sets like Latin-1 and ISO 8859-1 were developed to support international languages.
