    Study Notes

    CSS Fundamentals

    • CSS (Cascading Style Sheets) is a separate language from HTML used for defining the design of a webpage, including font size, margins, and colors.
    • HTML focuses on content, while CSS focuses on presentation.
    • CSS rules begin with a selector (e.g., p) followed by a declaration block enclosed in curly braces.
    • Properties within the block, like color, dictate how the selected HTML element appears.
    • CSS uses hexadecimal color values (e.g., #FF0000 for red).
    • Properties are key-value pairs similar to HTML attributes.

    Connecting CSS to HTML

    • CSS stylesheets are saved in .css files.
    • Linking a stylesheet to an HTML document uses the <link> element within the <head> section.
    • The <link> element's rel attribute signifies its purpose (e.g., stylesheet).
    • The href attribute points to the .css file. Links can be absolute, relative, or root-relative.
    • The browser finds the stylesheet through the HTML document's <link> element.

    CSS Properties and Values

    • color: sets text color; values are hexadecimal.
    • background-color: sets background color; values are hexadecimal.
    • CSS comments use /* */.
    • Units of measurement:
      • px (pixels): absolute size, independent of user settings.
      • em: relative size, based on parent element's font size.
    • Setting a base font size with em allows scaling across the entire page.
    • Multiple selectors can apply styles to several HTML elements with one rule.
    • font-family: sets typeface (e.g., "Helvetica", "Arial").
      • Fallback fonts are utilized when a requested font isn't available.
    • list-style-type: modifies bullet icons for <li> elements.
      • none is a useful option for styling list items that act like buttons.

    Styling Multiple Pages

    • CSS styles can be reusable across multiple HTML pages.
    • Linking a single stylesheet to multiple HTML documents.
    • Root-relative paths are better for referencing global stylesheets.

    Text Formatting

    • text-decoration: controls underlines, using none or line-through.
    • text-align: sets horizontal text alignment (left, center, right, justify).
    • font-weight: controls text boldness (e.g., bold, normal).
    • font-style: controls text italicization (italic, normal).

    CSS Cascading

    • CSS rules cascade from multiple sources: external stylesheets, page-specific styles, inline styles.
    • External Stylesheets are crucial for consistency and maintenance.
    • style attribute of HTML elements (inline styles). Should be avoided for maintenance.
    • Page-specific styles within the <style> tag of HTML. Should be avoided for maintenance.
    • Importance: Inline styles override page-specific styles, which override external stylesheets.

    Multiple Stylesheets

    • Multiple <link> elements allow incorporating styles from multiple files.
    • The order of <link> elements affects the hierarchy of styles.

    Responsive Design

    • CSS enables adapting web pages to different devices (mobile, tablet, desktop).
