Salesforce Lightning is a modern, intuitive, and powerful user interface framework created to enhance productivity, improve user experience, and make the Salesforce platform more customizable than ever before. If you’ve used Salesforce Classic before, you’ll immediately notice how Lightning feels faster, cleaner, and more aligned with how teams work today.

At its core, Salesforce Lightning is all about giving businesses a better way to sell, support, and collaborate using a beautifully redesigned interface and a robust component-based architecture.

Let’s break it down step by step.

Lightning offers:
