Study Notes

CSS Introduction

  • CSS (Cascading Style Sheets) defines the design of a web page, handling aspects like font sizes, margins, and colors.

  • It's separate from HTML, which defines content. CSS dictates how that content is displayed.

  • CSS rules have a selector (e.g., h1) which targets HTML elements, and a declaration block ({}) containing properties (e.g., color, font-size) that affect those elements.

  • CSS files have a .css extension.

  • CSS rules are applied to HTML elements.

  • Stylesheets are linked to HTML documents using the <link> element within the <head> section.

    • The <link> tag's rel attribute is set to stylesheet and its href attribute points to the CSS file.

Basic CSS Syntax

  • selector { property: value; } is the fundamental structure of a CSS rule.

  • The color property (e.g., #FF0000 for red) sets the text color.

  • Comments in CSS are /* ... */

  • Semicolons (;) are needed to separate declarations within a rule.

  • Background colors are set with background-color.

Linking CSS and HTML

  • Links between CSS and HTML let the browser load styles from .css files.

  • CSS, images, and JavaScript rely on HTML to link these elements together.

  • Links can be absolute, relative, or root-relative.

Using CSS Properties

  • text-decoration: none; to remove underlines from links.

  • text-decoration: line-through; to strikethrough text (use appropriate HTML elements for meaning instead).

  • text-align controls text alignment (left, center, right, justify but primarily affects entire page).

  • font-weight controls boldness (e.g., normal, bold).

  • font-style controls italicization (normal, italic).

  • font-family controls the font. Browsers try multiple font options.

Choosing Multiple Styles

  • Multiple selectors can apply styles to multiple HTML elements in one rule.

  • This reduces redundancy in CSS.

  • Commas separate selectors in a rule (e.g h1, h2, h3 { ... })

  • list-style-type alters bullet icons in lists ('none').

Combining styles across pages

  • Multiple .css files can be linked from multiple .html files.

  • External styles (in .css files) are preferred for readability and consistency of styles across your website.

  • Root-relative paths are used for referencing external stylesheets in nested pages to avoid confusion with file paths.

Types of CSS

  • External Style Sheets: Located in .css file, linked using <link> tags and applied to multiple .html files.
  • Page-Specific Styles: Styles within the <style> tag in the <head> section of an HTML file. Applied only to that single .html file.
  • Inline Styles: Styles applied directly in the HTML element's attributes (e.g., <p style="color:blue;">). Avoid this method.

CSS Hierarchy

  • Inline Styles have highest precedence (override external/page-specific rules and stylesheets).
  • Page-Specific styles (internal stylesheet)
  • External Stylesheets
  • Browser Defaults lowest priority.

Responsive Design

  • CSS is used to customize web pages for various devices (mobile, tablet, desktop) using media queries (not shown in this particular fragment).
