2D Game Development W/ Javascript & CSS3- Create Memory Game

Set up the html skeleton for a memory game with the doctype, html, head, and body. Define the title and meta information, charset UTF-8 and viewport, for a responsive page.

Design and implement the memory game's header and updates panel by adding a header with an id and h1, plus a timer, score, and new game button.

build a memory game area as a 4x5 grid of 20 cards, each with a front question mark and a back image, using 10 duplicated images for randomization via JavaScript.

create the opaque overlay and a result popup for the memory game, including the backdrop, a thumbs-up image, a header, a score message, and a great button.

Learn to link an external stylesheet and apply inline and internal CSS, reference styles from the head, and style elements using id and class selectors for a memory game interface.

Apply default browser styles with a universal selector and zero margins and padding; use box-sizing: border-box and user-select, including vendor prefixes for cross-browser compatibility.

Select the root to apply background color using hex or rgb values, then style the header with centered 90px text, three-pixel letter spacing, seven-pixel word spacing, and text shadow.

Learn to design the updates section and align it with the game by using float and display techniques, and adjust margins and font sizes while toggling visibility with display none.

Design the timer, score, and new game button with margins, fonts, colors, and shadows to create a cohesive user interface, and apply cascading style sheets concepts like margin collapsing.

Design the new game button for the memory game using CSS styling, borders, shadows, and hover effects. Use an id selector and cursor changes to enhance interactivity.

Shape the memory game area by sizing tiles to 150x140 using a 5-wide grid, setting a 775px container, and overlaying back and front faces with borders and shadows.

Design and align memory game cards in CSS, building front and back faces, arranging five cards per row with inline-block, borders, margins, padding, and hover-ready states.

Design the front and back of the card by absolutely positioning the layers, apply hover effects and a pointer cursor, and prepare rotation with transform for 0/180 degrees.

Explore css3 transformations and transitions to flip memory game cards with front and back faces, using transform rotateY(0deg) and rotateY(180deg) with a 0.5s linear transition and backface-visibility.

Design a full-page opacity screen with a fixed-position div that covers the page, uses a black background at adjustable opacity, and places the results pop-up above other elements.

Design the result popup for the memory game by creating a centered, fixed-position box with a high z-index, styled borders, and a dedicated image and heading.

Design the result popup for the memory game by styling the popup container with borders, padding, and border radius, and center the OK button with box shadow.

Learn how to connect HTML to CSS and JavaScript by linking styles and scripts, using proper file names and extensions, and placing the script at the bottom for reliable loading.

Explore variables and data types in JavaScript, learning how to declare names with var, assign strings, numbers, and booleans, and apply camelCase naming and semicolon rules.

Demonstrates basic JavaScript operators such as addition, subtraction, multiplication, division, and modulus; teaches using alerts, strings, and variables with concatenation to display sums and messages.

Master conditional statements in javascript, focusing on if and else statements. Learn to use comparison operators such as equal, greater than, less than, and not equal, with comments explaining code.

Explore switch statements in JavaScript by matching a value against multiple cases with break statements and a default; note cases can be numbers, strings, or booleans, unlike a simple if.

Learn how for loops power repetition in JavaScript using initialization, condition, and increment. See a for loop print numbers 1 to 5 and repeat until the condition is false.

Learn how one-dimensional arrays store multiple values in a single variable, access them by zero-based indices, and update elements, including strings and booleans, with both array constructors and literal syntax.

Explore two dimensional arrays by creating arrays within an array, assigning nested values, and accessing them with two indices to retrieve specific elements like 2 from the first subarray.

explore how JavaScript functions group code into reusable blocks, define a function, and call it repeatedly with arguments, returning values to the caller.

Learn how to manipulate a web page with the DOM using JavaScript, focusing on getElementById and innerText to retrieve elements, modify text, and respond to events.

Explore the DOM, manipulate elements with getElementById and text properties, and implement click events using addEventListener instead of inline on click attributes, ensuring separation of HTML and JavaScript.

Learn how to implement a left mouse down event on an element, attach an event listener with addEventListener, and change the element’s background color using camelCase CSS properties.

Explore implementing multiple mouse events on a single element by adding mouse down, mouse up, and mouse move listeners, and dynamically swap background colors between red, yellow, and green.

Build a seven-part memory game in JavaScript and CSS3, wiring DOM, enabling click flips, adding basic randomization, timer, and score, and replacing alerts with a custom popup.

Create and assign global variables to manage a memory game’s cards, flips, and scoring in JavaScript, including a 20-element record array, image decks, and two-card comparison logic.

Retrieve the game area and key HTML elements, set up global variables for timer, status, and game over, and prepare the new game flow to manage clicks and countdown.

Create a click event listener on the memory area to identify the clicked card via the event object, retrieve its id, and flip the card from front to back.

Implement card flipping in a memory game using JavaScript and CSS3, handling card IDs, extracting card numbers, and applying rotateY transforms to front and back elements.

Adjust image sizes for memory cards, implement flip logic with strict conditions, and build a basic memory game in JavaScript; no randomness or timer, using arrays to track flips.

Create a memory game with no randomization or timer, using arrays and a flip index to compare cards and a 600 ms delay to reveal results and flip back.

Create a basic memory game using javascript and css3, implement flip-back and result display functions, and manage game over conditions when the score reaches 10 or the timer runs out.

Create a flip back function that restores nonmatching cards to their front and back states using flipped indices and arrays, revealing the basic memory game's scoring and new game button.

Make the new game button work by adding a click listener that reloads the current page to start a fresh memory game. Attach it via the element id 'new'.

Randomize the game boxes on loading to generate a different set of images behind the cards each time, creating a more interactive memory game.

Randomize the memory game board on load by generating unique image indices with JavaScript's Math.random, using an image array and rounding to valid indices, ensuring no repeats.

Generate unique random numbers to populate the memory game board on load, ensuring no duplicates by checking against existing images, updating the board, and starting the timer after loading.

Start the timer when a new board loads, counting down from the given seconds and updating the timer display; stop at zero with clear timeout and show the result.

Replace the alert with a customized result popup that uses JavaScript to display the final score and win or try again messages, with dynamic innerHTML updates.

Wire the ok button to hide the results display and return to the game, update the score, and verify navigation between the results display and the game.
