Thymeleaf is a popular Java-based template engine used for server-side rendering in Spring Boot applications. It provides a simple and natural way to generate dynamic HTML content by seamlessly integrating with the Spring ecosystem.
To use Thymeleaf in a Spring Boot application, you must include the Thymeleaf Starter Dependency in your project's pom.xml file. Then, you can create HTML templates with Thymeleaf syntax, such as using expressions and tags to dynamically render data and logic within your web pages.
