Text Before HTML:

We are building a cryptocurrency portfolio tracker with real-time price updates.
 We'll use the provided template as inspiration for the design, but we'll adapt it for our use case.
 We'll use Tailwind CSS and the same fonts (Inter and Plus Jakarta Sans) and similar styling principles.

 Steps:
 1. Change the color scheme to something suitable for a crypto app (e.g., dark theme with accent colors like blue or green).
 2. Replace the content with cryptocurrency portfolio tracking:
    - Instead of "Build Tools", we'll have "Crypto Portfolio".
    - We'll have a list of cryptocurrencies with their current prices, changes, and portfolio value.
 3. We'll use a real-time data source (for example, CoinGecko or CoinCap) via API. However, note that we are only building the frontend.
    We'll simulate real-time updates with JavaScript setInterval for demonstration.

 Important: We are not using React, but plain HTML, Tailwind CSS, and JavaScript.

 Plan for the main content:
   - We'll have a header with the app name and a button to refresh or add a coin.
   - The main content will be a grid of cards for each cryptocurrency in the portfolio.
   - Each card will show:
        * Coin name and symbol
        * Current price
        * 24h change (with color indicating positive or negative)
        * Portfolio value (if the user has holdings) - for now, we can simulate with static data.
   - We'll also have a summary section for total portfolio value and 24h change.

 Since we are not using a backend, we'll use mock data and update the prices in real-time by fetching from an API (or simulate).

 We'll use the CoinGecko API for public data: https://www.coingecko.com/en/api

 However, note: CoinGecko API does not require an API key for public data.

 We'll fetch:
   - List of coins (or specific coins by id) to get the price and change.

 But for simplicity, we'll track a few coins: Bitcoin, Ethereum, Cardano, Solana, etc.

 We'll structure the page:

   Header: 
      Logo: "Crypto Portfolio"
      Maybe a button to refresh prices.

   Hero Section: 
      Instead of the hero text, we'll have a summary of the portfolio.

   Then a grid of coins.

   We'll also have a section for the current market data (like the ticker in the template, but for crypto).

   We'll use the same ticker animation for a marquee of top coins and their prices.

   We'll also have a footer.

 Let's define a new color scheme:

   Background: dark gray (like #0f172a) for the main background.
   Text: light gray (like #e2e8f0) for primary, and a lighter gray for secondary.
   Accent: green for positive changes, red for negative. And a blue for primary buttons.

   We'll define:

      --color-bg-main: 15, 23, 42;  // #0f172a
      --color-text-primary: 226, 232, 240; // #e2e8f0
      --color-text-secondary: 148, 163, 184; // #94a3b8
      --color-accent-green: 16, 185, 129; // #10b981
      --color-accent-red: 239, 68, 68; // #ef4444
      --color-accent-blue: 59, 130, 246; // #3b82f6

   We'll adjust the template's CSS variables accordingly.

   We'll also change the fonts to use the same as the template: Inter and Plus Jakarta Sans.

   We'll keep the same structure for the template but replace the content.

   We'll remove the sections that are not relevant (like features, pricing, etc.) and focus on the portfolio.

   We'll create:

      - A summary section (like the hero) that shows the total portfolio value and 24h change.
      - A grid of coins (each coin is a card) with:
          * Coin name and icon
          * Current price
          * 24h change (with color)
          * Portfolio value (if we are tracking holdings) - for now, we can show a static amount and then update the price in real-time.

   We'll simulate the portfolio data:

      [
        { id: 'bitcoin', name: 'Bitcoin', symbol: 'BTC', price: 0, change: 0, icon: 'url', amount: 0.5, total: 0 },
        ... 
      ]

   We'll update the price every 5 seconds.

   We'll use the CoinGecko API to get the price and change for each coin.

   API endpoint for a coin: 
        `https://api.coingecko.com/api/v3/coins/markets?vs_currency=usd&ids=bitcoin,ethereum,cardano,solana&order=market_cap_desc&per_page=100&page=1&sparkline=false`

   We'll get:
        id, symbol, name, image, current_price, market_cap, price_change_percentage_24h

   We'll then update our portfolio data with the current_price and price_change_percentage_24h.

   We'll calculate the total for each coin: amount * current_price.

   We'll also calculate the total portfolio value and the 24h change (sum of (amount * price_change) for each coin? or overall portfolio change?).

   For simplicity, we'll just show the total portfolio value and the overall change as the sum of the changes? 
   But note: the overall change is not the sum of the changes. It's the change from the total value 24h ago.

   However, we don't have the 24h ago value. So we can simulate by storing the previous total and then computing the change.

   Alternatively, we can use the portfolio value change from the API? But we don't have the user's holdings in the API.

   So for the demo, we'll just show the total portfolio value and the change as the average? or we can skip the overall change.

   We'll show:

        Total Portfolio Value: $X
        24h Change: +Y% (or -Y%)

   But without the historical data of the portfolio, we can't compute the exact change. So we'll simulate by:

        We'll store the previous total in a variable and then when we update the prices, we compute the new total and then the change.

        We'll set an interval to update the prices and then:

            newTotal = sum(coin.amount * coin.current_price)
            change = ((newTotal - oldTotal) / oldTotal) * 100

        Then update the oldTotal to newTotal for the next iteration.

   We'll start with oldTotal = initialTotal.

   We'll also have a button to refresh the prices.

   We'll structure the page:

      
 ... 

      

        
 ... 
        
 ... 
        
 ... 
  
      

   We'll use the same ticker animation from the template for the market ticker.

   We'll also have a footer.

   We'll remove the other sections (like features, pricing, etc.).

   We'll also change the navigation to have:

        Home, Portfolio, Market, etc. but for simplicity, we'll just have one page.

   We'll keep the mobile menu.

   We'll adjust the styles accordingly.

   Let's code accordingly.

   Note: We are not using the exact same structure as the template, but we are inspired by its design.

   We'll create a new HTML file.

   Steps:

      1. Change the title and meta description.
      2. Change the color variables.
      3. Change the fonts to Inter and Plus Jakarta Sans (same as template).
      4. Build the header with logo and a refresh button.
      5. Build the portfolio summary section (like the hero section) with:
            - Total portfolio value
            - 24h change
      6. Build the grid of coins (cards) for each cryptocurrency in the portfolio.
      7. Build a market ticker section (marquee) that shows the top coins and their current prices and changes.
      8. Build the footer.

   We'll use the same JavaScript for the mobile menu and the ticker animation.

   We'll add new JavaScript for:
        - Fetching the coin data from CoinGecko.
        - Updating the portfolio data and the DOM.
        - Setting an interval to update every 5 seconds.

   We'll also add a button to refresh the data.

   We'll use the same ticker animation for the market ticker.

   We'll also add a function to format numbers (currency, percentages).

   Let's code accordingly.

   Important: We are not using any framework, so we'll use vanilla JS.

   We'll create a function `updatePrices` that:

        - Fetches the coin data from CoinGecko for the coins we are tracking.
        - Updates the portfolio data (price and change for each coin).
        - Recalculates the total portfolio value and the 24h change (if we have the previous total).
        - Updates the DOM.

   We'll also have a function to format the numbers.

   We'll use:

        function formatCurrency(value) {
            return new Intl.NumberFormat('en-US', {
                style: 'currency',
                currency: 'USD',
                minimumFractionDigits: 2,
            }).format(value);
        }

        function formatPercent(value) {
            return new Intl.NumberFormat('en-US', {
                style: 'percent',
                minimumFractionDigits: 2,
                maximumFractionDigits: 2,
            }).format(value / 100);
        }

   But note: the API returns percentage as a number (e.g., 2.5 for 2.5%).

   We'll also have a function to update the ticker.

   We'll simulate the ticker with a list of coins and their prices, updating in real-time.

   We'll create a separate array for the ticker coins (maybe the same as the portfolio or more).

   We'll update the ticker with the same API call.

   We'll structure the portfolio data:

        let portfolio = [
            { id: 'bitcoin', name: 'Bitcoin', symbol: 'BTC', amount: 0.5, icon: '' },
            { id: 'ethereum', name: 'Ethereum', symbol: 'ETH', amount: 2, icon: '' },
            { id: 'cardano', name: 'Cardano', symbol: 'ADA', amount: 1000, icon: '' },
            { id: 'solana', name: 'Solana', symbol: 'SOL', amount: 5, icon: '' }
        ];

   We'll initialize the prices and changes to 0 and then update via the API.

   We'll also store the previous total for the portfolio change.

   We'll code accordingly.

   Let's start building the HTML structure.

   We'll remove the sections we don't need and add the ones we do.

   We'll keep the same header and footer structure.

   We'll change the hero section to be the portfolio summary.

   We'll change the grid to be the list of coins.

   We'll add a new section for the market ticker.

   We'll also change the navigation links to be: Home, Market, Portfolio, etc. but for now, we'll just have one page.

   We'll remove the pricing, features, etc.

   We'll also change the footer content.

   We'll code accordingly.

   Note: This will be a long HTML file.

   We'll break it down step by step.

   Let's go.
