WordPress, the ubiquitous content management system (CMS), is famous for its template system, which allows you to customize your website's appearance with ease. Adding a template to your WordPress website not only enhances its visual appeal but also ensures consistency across all your pages. Let's dive into how you can achieve this.

Before we start, make sure you have access to your WordPress dashboard and a template downloaded or designed, ideally in the form of a .zip file. Now, let's get started.

Uploading and Activating a WordPress Theme

A theme in WordPress is the same as a template, and it's usually a broader term that includes the template's functionality as well. Here's how you can upload and activate a theme:
