    Study Notes

    What is CSS?

    • CSS stands for Cascading Style Sheets, which are used for styling HTML documents.
    • It consists of a set of rules that describe how elements in a web page should be displayed.

    Application of CSS

    • CSS can be applied in three ways:
      • Inline: Directly within an HTML element using the style attribute.
      • Internal: Within a <style> tag inside the HTML document.
      • External: Linked to an HTML file using an external CSS file with a .css extension.

    CSS Syntax

    • The structure of CSS involves a selector followed by a declaration block:
      selector { property: value; }
    • Multiple declarations are allowed within a single block, but each property must only appear once.

    Selector Categories

    • Different types of selectors include:
      • Simple Selectors: Targeting single elements (e.g., type, class, ID).
      • Combinators: Define relationships between selectors (e.g., descendant, child, adjacent sibling).

    Simple Selectors

    • Example: Targeting headings (h2, h3) and paragraphs (p) for specific styles.

    Combinators

    Descendant Selector

    • Targets elements that are nested within a specified ancestor element.

    Direct Child Selector

    • Selects elements that are immediate children of a specified parent.

    Adjacent Sibling Selector

    • Matches an element that is directly following another element within the same parent.

    General Sibling Selector

    • Matches elements that follow another element, not necessarily immediately, within the same parent.

    Class and ID Selectors

    • Classes are denoted with a dot (.) and are preferred for reuse; IDs are denoted with a hash (#) and should be unique.

    Universal Selector

    • The universal selector (*) applies styles to all elements on a page.

    List Properties

    • Properties for ordered and unordered lists include list-style-type, list-style-position, and list-style-image.
    • Link properties include different states: :link, :visited, :hover, and :active, each allowing specific style adjustments.

    Text and Font Properties

    • Text properties include alignment, spacing, indentation, and color.
    • Font properties consist of family, size, style, weight, and transformation.

    Fonts

    • Two main font categories:
      • Serif: Includes fonts with serifs (e.g., Times New Roman, Georgia).
      • Sans-serif: Fonts without serifs, which are easier to read on screens (e.g., Arial, Helvetica).

    Comments in CSS

    • Comments can be added in CSS files using the format /* comment */.

    CSS Validation

    • Use the W3C CSS Validator to ensure proper syntax in style sheets.

    Practical Applications

    • Assign styles using different selector types on provided HTML and CSS files.
    • Use various properties such as background-color, padding, border, and list-style-type to practice CSS styling.
