More professionalism with S.P.A.R.K!

In this stage we are attempting to make the page more professional with the inclusion of a favicon and other elements we'll mention soon.

Obviously since this is a game, we need to improve it as well.

User: This is Stage 3 in our Hangman Saga. Would you please write the necessary code to put a favicon in the browser tab? I have the image in our images folder. Remember, we will be documenting our adventure here, so I've included a chatlog for this stage, and this will be our first entry. Please include the reasoning behind having a favicon in a design. Note the necessary styles in the chatlog document
GitHub Copilot:

Certainly! Here’s how to add a favicon to your project, plus a brief explanation for your chatlog documentation.

Why Add a Favicon?
A favicon (short for "favorite icon") is the small image that appears in the browser tab next to your page title. It helps users quickly identify your site among many open tabs or bookmarks, adds a professional touch, and strengthens your site’s branding.

How to Add a Favicon

  1. Place your favicon image (e.g., favicon.png) in your images folder.
  2. Add this line inside your <head> section (preferably after your <title> tag):
<link rel="icon" type="image/png" href="images/favicon.png">

If your favicon is .ico, use type="image/x-icon" and href="images/favicon.ico".

Example Chatlog Entry
User: How do we add a favicon to our Hangman Saga project?
Copilot: A favicon is a small icon that appears in the browser tab. It helps users recognize your site and adds a professional touch. To add one, place your favicon image in the images folder and add a <link rel="icon" ...> tag in your HTML <head>. For example:

<link rel="icon" type="image/png" href="images/favicon.png">
This will display your chosen icon in the browser tab.

User: Our favicon works great! Would you please put our current dialogs (including this one) in this document? It would start between the 'start' and 'end' comment areas.
GitHub Copilot:

Certainly! To document our dialogs, we can simply copy and paste the relevant sections between the 'start' and 'end' comments in this HTML file. This way, we keep a record of our conversation and the evolution of our Hangman Saga project.

User: I noticed you mentioned a 'vulnerability' involving 'hardcoded-credentials' Please explain and how do I fix it? Let's add this to the chatlog too!
GitHub Copilot:

What is a 'hardcoded-credentials' vulnerability?
A hardcoded-credentials vulnerability happens when sensitive information—like usernames, passwords, API keys, or tokens—is written directly into your source code. This is risky because anyone with access to your code (including public repositories) can see and misuse these credentials.

How do I fix it?

Example: Instead of const password = "mySecret123"; in your JS, store secrets in a secure location and access them only on the server.

User: Please make a 'Stage 3 Card' with the title: 'Stage 3: Professional Touches and Improved Game Play. The bottom link should take us to hangmanStg3.html. Add this interaction to the chatlog
GitHub Copilot:

Certainly! Here’s the code for a Stage 3 card to add to your index page: 

<div class="col-md-6 col-lg-4">
    <div class="card stage-card shadow h-100">
        <div class="card-body d-flex flex-column">
            <h5 class="card-title">Stage 3: Professional Touches and Improved Game Play</h5>
            <p class="card-text flex-grow-1">
                This stage introduces a professional favicon, improved documentation, and enhanced game play features. Explore the chatlog to see our design decisions and security best practices as we continue our Hangman coding adventure!
            </p>
            <ul>
                <li><a href="hangmanChatlogStg3.html">Chat Log</a></li>

Add this card to your hangmanIndex.html file alongside the other stage cards.

User: I highlighted the code that holds the game play content and asked you to wrap it in div#gameContent that was not going to be displayed until the page loaded. (I used Ctrl-I to do this). You did it perfectly! Please document what you did and also add a p#loadingPara that shows that the page is 'loading' and then hide that once it's loaded. Add this to the chat log, please.
GitHub Copilot:

Certainly! Here’s what was done:

This improves user experience by preventing partially rendered game elements from appearing before the page is ready. 

<p id="loadingPara" class="text-muted">Loading, please wait...</p>
<div id="gameContent" style="display:none;">
    ...game content...
</div>
<script>
window.addEventListener('DOMContentLoaded', function() {
    document.getElementById('gameContent').style.display = '';
    document.getElementById('loadingPara').style.display = 'none';
});
</script>
User: At this point, the game loads almost instantaneously. Can we add a 2 sec delay so we can see the 'loading paragraph' just to give the illusion that something cool is about to happen (suspense!) Is this a good idea? Be honest
GitHub Copilot:

Yes, you can add a 2-second delay to show the loading message for dramatic effect. Here’s how you can do it: 

<script>
window.addEventListener('DOMContentLoaded', function() {
    setTimeout(function() {
        document.getElementById('gameContent').style.display = '';
        document.getElementById('loadingPara').style.display = 'none';
    }, 2000);
});
</script>

Is this a good idea?
Adding a short delay can create suspense and make the game feel more dramatic, which is fun for demos or classroom use. However, for regular users, artificial delays can be frustrating—people usually prefer content to load as quickly as possible. For your project, it’s fine as a teaching or dramatic tool, but in production, it’s best to avoid unnecessary delays.

User: You cleverly provided some thematic words in line 4. If you were to provide a theme name for them, what would it be and can you add 10 more words with that theme?
GitHub Copilot:

The current word list theme is "Programming & Technology".
Here are 10 more words that fit this theme (but for our project, we’ll only use those relevant to our code):
ALGORITHM, VARIABLE, FUNCTION, OBJECT, SYNTAX, ARRAY, DEBUGGING

User: Let's call it 'Hangman Technology' as a theme and include it as a variable associated with 'words' and let's only use words associated with our current program. Therefore, we would need to remove 'PYTHON' and 'RECURSION' and 'COMPILER' since we've not used those ideas here. To give the user a hint as to what the word is, let's list the theme above the word blanks.
GitHub Copilot:

The theme is now set as Hangman Technology and is stored in a theme variable. The words array only includes terms relevant to our current program. To help the user, the theme is displayed above the word blanks using the updateThemeDisplay() function, which is called at the start of each game. 

// Theme for the current word list
const theme = "Hangman Technology";

// List of possible words (all related to our current program)
const words = [
    "JAVASCRIPT", "BOOTSTRAP", "PROGRAM", "HANGMAN", "COMPUTER",
    "ALGORITHM", "VARIABLE", "FUNCTION", "OBJECT", "SYNTAX",
    "ARRAY", "DEBUGGING"
];

// --- Display the theme above the word blanks ---
function updateThemeDisplay() {
    let themeDiv = document.getElementById("themeDisplay");
    if (!themeDiv) {
        themeDiv = document.createElement("div");
        themeDiv.id = "themeDisplay";
        themeDiv.className = "text-center mb-2 fw-bold";
        const wordDisplay = document.getElementById("wordDisplay");
        wordDisplay.parentNode.insertBefore(themeDiv, wordDisplay);
    }
    // Show theme and word length
    themeDiv.innerHTML = `Theme: ${theme}<br>Word length: ${selectedWord.length}`;
}

// --- Display the word with underscores and guessed letters ---
function updateWordDisplay() {
    let display = "";
    for (let letter of selectedWord) {
        if (guessedLetters.includes(letter)) {
            display += letter + " ";
        } else {
            display += "_ ";
        }
    }
    document.getElementById("wordDisplay").textContent = display.trim();
}

Summary of changes:

User: Given the nature of this playful word game, what google font(s) would you recommend?
GitHub Copilot:

For a playful word game like Hangman, I recommend using Google Fonts that are fun, friendly, and highly readable. Here are some great choices:

Example combo:
Use Luckiest Guy for your main title/headings and Fredoka or Quicksand for body text and UI elements.

How to add (example with Fredoka and Luckiest Guy): 

<link href="https://fonts.googleapis.com/css2?family=Fredoka:wght@400;700&family=Luckiest+Guy&display=swap" rel="stylesheet">
<style>
    body { font-family: 'Fredoka', Arial, sans-serif; }
    .hero-title, h1 { font-family: 'Luckiest Guy', cursive; }
</style>

Let me know if you want a specific pairing or want to see how it looks in your code!

User: For each of the font names in the list items, can you style them to have the actual font associated with the word? For example, Baloo 2 would be styled with Baloo 2, and so on. Put this entry in our chatlog too
GitHub Copilot:

Absolutely! Here are the font suggestions, each styled with its actual Google Font for a live preview:

Now you can see how each font looks right in the chatlog!

User: Please make the font size of those font names 50% bigger so we can see them better
GitHub Copilot:

The font preview classes have been updated to increase the font size by 50% for better visibility. Here’s the CSS used: 


.font-fredoka { font-family: 'Fredoka', Arial, sans-serif; font-size: 2.25em; }
.font-baloo { font-family: 'Baloo 2', cursive, sans-serif; font-size: 2.25em; }
.font-luckiest { font-family: 'Luckiest Guy', cursive, sans-serif; font-size: 2.25em; }
.font-quicksand { font-family: 'Quicksand', Arial, sans-serif; font-size: 2.25em; }
.font-comicneue { font-family: 'Comic Neue', cursive, sans-serif; font-size: 2.25em; }

Now each font name in the list appears 50% larger, making it easier to compare and choose your favorite style!

User: I'm sure there will be users who will want to provide their own themes and words. Can you create a new page: userProvidedThemedWords.html where a user can provide a collection of words and submit it for play. It could be stored in localStorage as userWords and then loaded into the game if the software sees that it is not empty. To guide the user, please pre-populate the theme input field with 'Marvel Heroes and Villains' and the text area with an alphabetized list of characters from the Marvel universe. Next to the 'Hangman' link in the nav bar, provide a link to this new page: Use my words
GitHub Copilot:

Absolutely! Here’s how we enabled users to provide their own themes and word lists for Hangman:

Key localStorage integration code: 

// In hangmanScript3.js
let theme = "Hangman Technology";
let words = [
    "JAVASCRIPT", "BOOTSTRAP", "PROGRAM", "HANGMAN", "COMPUTER",
    "ALGORITHM", "VARIABLE", "FUNCTION", "OBJECT", "SYNTAX",
    "ARRAY", "DEBUGGING"
];

// Check for user-provided theme and words
if (localStorage.getItem('userTheme') && localStorage.getItem('userWords')) {
    theme = localStorage.getItem('userTheme');
    try {
        words = JSON.parse(localStorage.getItem('userWords'));
    } catch (e) {
        // fallback to default if parsing fails
    }
}

On the userProvidedThemedWords.html page, the form saves to localStorage like this: 

document.getElementById('userWordsForm').addEventListener('submit', function(e) {
    e.preventDefault();
    const theme = document.getElementById('themeInput').value.trim();
    const wordsRaw = document.getElementById('wordsInput').value.trim();
    const words = wordsRaw.split('\n')
        .map(w => w.trim().toUpperCase())
        .filter(w => w.length > 0);
    if (theme && words.length > 0) {
        localStorage.setItem('userTheme', theme);
        localStorage.setItem('userWords', JSON.stringify(words));
        document.getElementById('saveMsg').style.display = '';
    }
});

This allows users to create and play Hangman with their own custom themes and word lists!

User: In function 'createLetterButtons' we need to include a space character (Denonte it with an underscore) in case a word from the word bank has a space. Please include this entry update in chatlog
GitHub Copilot:

The createLetterButtons function was updated to include a button for the space character, represented visually as an underscore (_). This allows users to guess spaces in multi-word phrases from the word bank. 

// --- Create letter buttons (A-Z and space) ---
function createLetterButtons() {
    // ...existing code for A-Z...
    // Add a button for space (displayed as underscore)
    const spaceBtn = document.createElement("button");
    spaceBtn.textContent = "_";
    spaceBtn.title = "Space";
    spaceBtn.className = "btn btn-outline-secondary m-1";
    spaceBtn.disabled = guessedLetters.includes(" ") || wrongGuesses.includes(" ");
    spaceBtn.onclick = () => handleGuess(" ");
    container.appendChild(spaceBtn);
}

Now, if a word or phrase contains spaces, users can guess them just like any other letter!

User: Likewise, there may be words with a hypen (like Spider-man) so please add a hypen to the set of button characters and update the chatlog too
GitHub Copilot:

The createLetterButtons function was further updated to include a button for the hyphen (-), in addition to the space character. This allows users to guess hyphens in words or names like "SPIDER-MAN" from the word bank. 

// --- Create letter buttons (A-Z, space, and hyphen) ---
function createLetterButtons() {
    // ...existing code for A-Z...
    // Add a button for space (displayed as underscore)
    const spaceBtn = document.createElement("button");
    spaceBtn.textContent = "_";
    spaceBtn.title = "Space";
    spaceBtn.className = "btn btn-outline-secondary m-1";
    spaceBtn.disabled = guessedLetters.includes(" ") || wrongGuesses.includes(" ");
    spaceBtn.onclick = () => handleGuess(" ");
    container.appendChild(spaceBtn);

    // Add a button for hyphen
    const hyphenBtn = document.createElement("button");
    hyphenBtn.textContent = "-";
    hyphenBtn.title = "Hyphen";
    hyphenBtn.className = "btn btn-outline-secondary m-1";
    hyphenBtn.disabled = guessedLetters.includes("-") || wrongGuesses.includes("-");
    hyphenBtn.onclick = () => handleGuess("-");
    container.appendChild(hyphenBtn);
}

Now, if a word or phrase contains spaces or hyphens, users can guess them just like any other letter!

User: If one of the missing letters is a space, please replace it with a '*' so can 'see' it. Put this in the chatlog
GitHub Copilot:

The updateWordDisplay function was updated so that if a missing letter is a space, it is shown as * instead of an underscore. This makes spaces in the answer visible to the player, helping them distinguish between word breaks and regular missing letters. 

function updateWordDisplay() {
    let display = "";
    for (let letter of selectedWord) {
        if (guessedLetters.includes(letter)) {
            display += letter + " ";
        } else if (letter === " ") {
            display += "* ";
        } else {
            display += "_ ";
        }
    }
    document.getElementById("wordDisplay").textContent = display.trim();
}

Now, unguessed spaces will appear as * in the word display!

User: Oops. I meant to say, replace the space with a '*' once it is guessed. It should stay as a underscore until the user presses the _ button to reveal it
GitHub Copilot:

The updateWordDisplay function was updated so that a space remains as an underscore (_) until the user guesses it (by pressing the _ button). Once guessed, the space is shown as * in the word display. 

function updateWordDisplay() {
    let display = "";
    for (let letter of selectedWord) {
        if (guessedLetters.includes(letter)) {
            // If the guessed letter is a space, show '*'
            display += (letter === " " ? "* " : letter + " ");
        } else {
            display += "_ ";
        }
    }
    document.getElementById("wordDisplay").textContent = display.trim();
}

Now, spaces are only revealed as * after the user guesses them!
