# RuntimeContainer

## Overview

The `RuntimeContainer` class is designed to manage the styling of a container in a dynamic environment. One of its primary functions is to modify the visual appearance of the container by adding or removing style classes. This functionality allows for flexibility in managing the container’s style dynamically during runtime.

Additionally, the class provides methods to check for specific set of style classes in the container. This can be particularly useful for making conditional styling decisions based on the container's current style state.

For more granular control over the container's appearance, the `setCSSStyle()` and `removeCSSStyle()` methods may be used.
