CSS isolation

CSS isolation is a concept that allows you to encapsulate styles within a specific scope, preventing them from affecting elements outside of that scope. This can be useful for avoiding style conflicts in larger projects or when using third-party libraries.

There are several ways to achieve CSS isolation in your projects, including using naming conventions, CSS modules, and CSS-in-JS solutions. In this tutorial, we will focus on using naming conventions to isolate styles.

Using naming conventions for CSS isolation

One common approach to CSS isolation is to use naming conventions to scope styles to a specific component or section of your project. This usually involves prefixing class names with a unique identifier to ensure they only apply to elements within that scope.

For example, let's say we have a simple button component that we want to style without affecting other buttons on the page. We can achieve this by prefixing the class names in our CSS with a unique identifier for the button component.

.button {
  background-color: blue;
  color: white;
  padding: 10px 20px;
}

.button-primary {
  background-color: green;
}

In the example above, the .button class styles all buttons with a blue background and white text color, while the .button-primary class styles primary buttons with a green background. By using unique class names for our button styles, we can isolate them to only apply to the buttons within our component.

By following naming conventions like this, you can effectively isolate styles within your project and avoid conflicts between different parts of your CSS.
