CSS in 2 min.

🔹 CSS Basics

➡️ CSS stands for Cascading Style Sheets
➡️ Used to style HTML elements
➡️ Three ways to apply CSS: Inline, Internal, External
➡️ External CSS uses a .css file linked via <link>
➡️ CSS rules have selectors and declaration blocks
➡️ Declaration blocks contain properties and values

🔹 CSS Syntax

➡️ Selector targets the HTML element
➡️ Declaration block is enclosed in {}
➡️ Each declaration has a property: value; pair
➡️ Multiple declarations are separated by semicolons

🔹 CSS Selectors

➡️ * selects all elements
➡️ element targets specific elements like p, div
➡️ .class selects elements with a specific class
➡️ #id selects a specific ID
➡️ element, element targets multiple elements
➡️ element element selects descendants
➡️ element > element selects direct children
➡️ element + element selects adjacent siblings
➡️ element ~ element selects general siblings
➡️ [attribute] targets by attribute

🔹 Text and Font Styling

➡️ color sets the text color
➡️ font-family sets the font
➡️ font-size sets the text size
➡️ font-weight makes text bold or light
➡️ font-style sets italic or normal
➡️ text-align aligns text (left, center, right, justify)
➡️ text-decoration adds underline, overline, or line-through
➡️ line-height controls spacing between lines
➡️ letter-spacing adjusts space between letters
➡️ text-transform changes text case (uppercase, lowercase, capitalize)

🔹 Box Model

➡️ Every element is a box: content → padding → border → margin
➡️ width and height control content size
➡️ padding controls space inside the element
➡️ border defines the edge
➡️ margin controls space outside the element
➡️ box-sizing: border-box includes padding and border in width/height

🔹 Backgrounds

➡️ background-color sets background color
➡️ background-image sets background image
➡️ background-repeat controls repetition
➡️ background-size defines scaling (cover, contain)
➡️ background-position sets image position
➡️ background-attachment: fixed makes background stay during scroll

🔹 Borders

➡️ border sets width, style, and color
➡️ border-radius creates rounded corners
➡️ border-top, border-right, etc., for individual sides

🔹 Margins and Padding

➡️ margin adds space outside the element
➡️ padding adds space inside the element
➡️ You can set them individually: top, right, bottom, left
➡️ Shorthand: margin: 10px 20px; for vertical/horizontal spacing

🔹 Display and Positioning

➡️ display defines how elements are rendered: block, inline, inline-block, flex, grid, none
➡️ visibility: hidden hides the element but retains space
➡️ position:
 ➡️ static (default)
 ➡️ relative (moves relative to its position)
 ➡️ absolute (relative to nearest positioned ancestor)
 ➡️ fixed (relative to viewport)
 ➡️ sticky (sticks during scroll)
➡️ top, right, bottom, left work with positioning

🔹 Flexbox

➡️ display: flex activates flex container
➡️ flex-direction sets direction (row, column)
➡️ justify-content aligns items horizontally
➡️ align-items aligns items vertically
➡️ flex-wrap controls wrapping
➡️ align-self overrides alignment for a single item
➡️ gap sets spacing between items

🔹 CSS Grid

➡️ display: grid activates grid layout
➡️ grid-template-columns and grid-template-rows define structure
➡️ gap sets spacing
➡️ grid-column and grid-row span items
➡️ justify-items and align-items align content

🔹 Colors and Units

➡️ Colors:
 ➡️ Named (e.g. red)
 ➡️ Hex (#ff0000)
 ➡️ RGB (rgb(255,0,0))
 ➡️ RGBA (with transparency)
➡️ Units:
 ➡️ px, em, rem, %, vh, vw

JavaScript in 5 min👇

🔹 JavaScript Basics

➡️ JavaScript is a noscripting language for web development
➡️ Runs in the browser or server (via Node.js)
➡️ Case-sensitive and dynamic (no fixed data types)
➡️ Statements end with ; (optional but recommended)
➡️ Use // for single-line comments and /* */ for multi-line comments

🔹 Variables

➡️ Use let and const for block-scoped variables
➡️ Use var (function-scoped; avoid in modern code)
➡️ const is used for constants (cannot be reassigned)
➡️ Variable names must start with a letter, _, or $

🔹 Data Types

➡️ Primitive Types: string, number, boolean, null, undefined, symbol, bigint
➡️ Reference Types: object, array, function
➡️ Use typeof to check type

🔹 Operators

➡️ Arithmetic: +, -, *, /, %, **
➡️ Assignment: =, +=, -=, *=, /=, etc.
➡️ Comparison: ==, ===, !=, !==, >, <, >=, <=
➡️ Logical: &&, ||, !
➡️ Ternary: condition ? true : false
➡️ Nullish Coalescing: ??

🔹 Control Flow

➡️ if, else if, else for conditionals
➡️ switch for multiple conditions
➡️ for, while, do...while for loops
➡️ break exits a loop, continue skips an iteration

🔹 Functions

➡️ Declare with function keyword
➡️ Arrow functions: const name = () => {}
➡️ Parameters are listed in ()
➡️ Functions can return values using return
➡️ Can be assigned to variables or passed as arguments

🔹 Arrays

➡️ Arrays are list-like objects
➡️ Use [] to declare
➡️ Common Methods:
 ➡️ push(), pop(), shift(), unshift()
 ➡️ slice(), splice(), concat(), join()
 ➡️ map(), filter(), reduce(), forEach()
➡️ Use length to get array size
➡️ Index starts at 0

🔹 Objects

➡️ Objects store key-value pairs
➡️ Declare using { key: value }
➡️ Access with dot . or bracket [] notation
➡️ Use Object.keys(), Object.values(), Object.entries()
➡️ Use delete to remove a property

🔹 Strings

➡️ Strings can use single or double quotes
➡️ Template literals use backticks `, and ${} for variables
➡️ Common Methods:
 ➡️ length, toUpperCase(), toLowerCase()
 ➡️ includes(), indexOf(), slice(), substring()
 ➡️ replace(), split(), trim()

🔹 Math & Numbers

➡️ Use Math object:
 ➡️ Math.round(), Math.floor(), Math.ceil()
 ➡️ Math.random(), Math.max(), Math.min()
➡️ Use parseInt(), parseFloat() to convert strings
➡️ Use Number() to convert any type to number

🔹 Date and Time

➡️ Use new Date() to create date objects
➡️ Methods:
 ➡️ getFullYear(), getMonth(), getDate()
 ➡️ getHours(), getMinutes(), getSeconds()
➡️ Use set...() to change date/time values

🔹 Events

➡️ Events are actions like click, hover, etc.
➡️ Use addEventListener() to handle events
➡️ Common Events: click, submit, input, keydown, load
➡️ The event object contains details about the event

🔹 DOM Manipulation

➡️ DOM = Document Object Model
➡️ Select Elements:
 ➡️ getElementById(), getElementsByClassName()
 ➡️ querySelector(), querySelectorAll()
➡️ Modify Content:
 ➡️ textContent, innerText, innerHTML
➡️ Modify Styles:
 ➡️ http://element.style.property = value
➡️ Modify Classes:
 ➡️ classList.add(), remove(), toggle()
➡️ Create/Remove Elements:
 ➡️ createElement(), appendChild(), removeChild()

🔹 ES6+ Features

➡️ let and const for modern variable declarations
➡️ Arrow functions for concise syntax
➡️ Template literals with ${}
➡️ Destructuring objects and arrays
➡️ Spread (...) and Rest (...) operators
➡️ Default parameters in functions
➡️ Modules using export and import
➡️ Promises and async/await for handling async code

Prompting is a Great skill.

Master it.

This is a very smart move by the United Arab Emirates.

Providing free access to OpenAI’s ChatGPT for their ~11 million residents & citizens may cost around $3 billion annually, but even a 1% AI-boost in productivity could double that in GDP gains, excellent return on investment!
