# Dynamic Frontend Implementation Guide

## Overview
Both the **Service Section** and **Blog Section** in `index.php` have been completely redesigned to be **dynamic** and **responsive**. All content is now pulled from the database via API endpoints and syncs automatically with the admin dashboard.
