Okay, let's start setting up the basic structure and logo for your social media app, Beco. /* Light Mode Variables */ :root { --bg-color-light: #F5F5F5; --text-color-light: #333333; --primary-color-light: #3A405A; /* Cold Dark Blue */ --secondary-color-light: #A0D2DB; /* Cold Blue */ --logo-fill-light: url(#becoGradient); /* Use gradient for logo */ --bg-color-dark: #1E1E1E; --text-color-dark: #E0E0E0; --primary-color-dark: #A0D2DB; /* Cold Blue */ --secondary-color-dark: #3A405A; /* Cold Dark Blue */ --logo-fill-dark: url(#becoGradient); /* Use gradient for logo */ } /* Default to Light Mode */ body { background-color: var(--bg-color-light); color: var(--text-color-light); font-family: sans-serif; margin: 0; padding: 20px; transition: background-color 0.3s, color 0.3s; } h1 { color: var(--primary-color-light); } .logo-container img { width: 150px; /* Adjust size as needed */ height: auto; } /* Dark Mode */ @media (prefers-color-scheme: dark) { body { background-color: var(--bg-color-dark); color: var(--text-color-dark); } h1 { color: var(--primary-color-dark); } /* You might need JS to dynamically change SVG fill based on theme, or use CSS variables within SVG if supported, or provide separate light/dark logos */ } /* Example usage */ .button-primary { background-color: var(--primary-color-light); color: var(--bg-color-light); border: none; padding: 10px 20px; border-radius: 5px; cursor: pointer; transition: background-color 0.3s; } .button-primary:hover { opacity: 0.9; } @media (prefers-color-scheme: dark) { .button-primary { background-color: var(--primary-color-dark); color: var(--bg-color-dark); } } Beco

Welcome to Beco

Your new social space.

This sets up: 1. An `index.html` file as the main entry point. 2. A `style.css` file with CSS variables for light and dark modes using your specified cold blue (`#A0D2DB`) and cold dark blue (`#3A405A`) colors. It includes basic styling and uses `@media (prefers-color-scheme: dark)` to detect the user's system preference. 3. A `logo.svg` file containing a simple text-based logo for "Beco" using a gradient of the specified colors. 4. The HTML file embeds the SVG logo directly. You can see the basic structure and the logo now. The CSS automatically adapts to your system's light or dark mode preference.
