SnapGrid — Social Media Dashboard (Assignment 3)

Files

• index.html — the app UI
• styles.css — styling for light/dark theme and layout
• solutions.js — where the assignment JavaScript is implemented

Features implemented

• Theme toggle (Dark / Light mode)
• Follow / Unfollow with live follower counter
• Post composer with character counter and live posting
• Like / Unlike functionality for posts (counts and total)
• Hashtag filtering and basic hashtag styling for new posts

How to run

1. Open index.html in your browser. On macOS you can double-click the file or serve it with a simple HTTP server.

   Example (from project folder):

   # using Python 3 built-in server
   python3 -m http.server 8000
   # then open http://localhost:8000 in your browser

2. Interact with the UI:

   • Toggle theme with the top-right button.
   • Click Follow to change follower count.
   • Compose a post and click Post to add a new post to the feed.
   • Click the heart on any post to like/unlike and update totals.
   • Click hashtag pills to filter posts by tag.

Notes & testing tips

• New posts created via the composer are sanitized to prevent HTML injection and hashtags are wrapped in a .hashtag span for styling.
• If likes on newly-created posts don't respond, ensure attachLikeListeners() is being called after the post is inserted into the DOM.
• For quick development, use a browser devtools console to inspect elements or to call helper functions defined in solutions.js.
