Study Notes

CSS Summary

CSS is a stylesheet language that defines how HTML elements are displayed (on screen, paper, etc.).
It controls the presentation of an HTML (or XML) document.
CSS streamlines webpage layout design across multiple pages.
External CSS files store styles for reuse.

CSS Syntax

A CSS rule-set comprises a selector and a declaration block.
The selector identifies the HTML element to style.
The declaration block contains declarations (property-value pairs).
Each declaration has a property name and a value, separated by a colon.
Declarations are separated by semicolons; the block is enclosed in curly braces.
Example: h1 {color: blue; font-size: 12px;}

Three Ways to Insert CSS

Inline: Applying styles directly within an HTML element's style attribute.
Internal: Defining styles within an HTML document's <style> element, usually in the <head> section.
External: Linking to a separate CSS file using a <link> tag in the HTML <head>. This is the common practice for larger projects.

CSS Selectors

Element: Selects all elements of a specific type (e.g., h1 {color: red;}).
Class: Selects elements with a particular class (e.g., .center {text-align: center;}). Use a '.' before the class name in CSS.
ID: Selects a single element with a unique ID (e.g., #header {background-color: blue;}). Use a '#' before the ID name in CSS.

Divs and CSS

Div: An HTML element used to container content.
CSS Classes: Reusable styles for multiple elements.
Classes in HTML: Use the class attribute to apply classes (e.g., <div class="center">).
Styling Classes in CSS: Use a dot (.) before the class name: .center {text-align: center;}

Additional CSS Concepts

IDs: Unique identifiers for elements.
HTML Structure: Use <div> to group related content; use <h2> and  for headings and paragraphs within the <div>.
CSS Styling: Use classes like center, underline, or blue for reusable styles.
External CSS: Stores styles separately from the HTML document.

More CSS Examples

Background colors: Apply colors to various HTML elements.
Text alignment: Center text within elements.
Interactive image maps: Allow users to navigate to different pages by clicking on image regions.
Flexible layouts (using flexbox): Arrange multiple elements side-by-side using display: flex. The height and width are commonly used with % (percentage).
