Study Notes

HTML Entities

  • Entities are sets of words and symbols used to display special characters.
  • Examples include copyright (©), degree (°), dollar ($), percent (%), and registered trademark (®).
  • Entities can be displayed using entity names (like &copy;) or numerical codes (like &#169;).
  • Using numerical codes is generally more compatible across different browsers.
  • UTF-8 encoding is the recommended standard for HTML5. Websites should include meta charset="UTF-8" in the <head> section.

HTML Attributes

  • Attributes modify HTML tags to provide additional information or instructions.
  • Attributes are written in the form attribute="value" within an opening tag.
  • Example: <a href="http://google.com">Go to Google Site</a>
  • href is the attribute, and http://google.com is the attribute value.

HTML Tags

  • Tags are keywords enclosed in angle brackets (e.g., <html>) forming the structure of an HTML document.
  • Some tags define structural elements like <html>, <head>, <body>.
  • Formatting tags change the appearance of text, such as <b> (bold), <i> (italic), and <font>.
  • Paired tags: These tags come in pairs with opening and closing tags that surround content (e.g., <p>, </p>).
  • Structural tags: Tags that are fixed and fundamental to HTML (e.g., <!doctype>, <html>, <head>, <title>, <body>).
  • Formatting tags provide visual formatting to content.
  • Some notable tags:
    • <br/> or <br>: Creates a single line break.
    • <h1> to <h6>: Defines headings of varying importance.
    • <p>: Defines a paragraph.
    • <pre>: Defines preformatted text.
    • <small>: Renders text smaller than surrounding text.
    • <strike>: Places a line through the text.
    • <center> </center>: Centers the content.
    • <blockquote> : Defines a long quotation
    • <strong> : Defines important text.
    • <sub/>: Text placed as subscript.
    • <sup/>: Text placed as superscript.
    • <tt/>: Text formatted like typewriter text.
    • <u>: Used for underlining.
  • Nesting is placing one tag inside another.

HTML5 Considerations

  • HTML5 is more flexible and often uses CSS for formatting. Using some HTML5 tags like font, center, and strike might not be supported or may not function the same way as in older versions.

General Tips

  • Using UTF-8 is recommended for encoding special characters.
  • Use CSS for more advanced formatting.
  • Use meta charset="UTF-8" in the <head> section.
