Local Scope in CSS Modules
Styles in traditional CSS are applied worldwide, which makes it difficult to prevent accidental style overrides and naming conflicts. By establishing local scope, which keeps styles defined inside a module separate from the rest of the application, CSS Modules solve this problem.
Example: Let’s consider a simple example to illustrate the local scope concept in CSS Modules. Assume you have a button component with a CSS file named “button.module.css”. In this example, the styles for the button are defined with a class named “.button“. However, the key difference is that these styles are locally scoped to the “button” module.
/* button.module.css */
.button {
background-color: #3498db;
color: #ffffff;
padding: 10px 15px;
border: none;
border-radius: 5px;
cursor: pointer;
}
.button:hover {
background-color: #217dbb;
}
CSS Modules : Local Scope for styles in React
CSS Modules enable you to write styles in CSS files and then consume them as JavaScript objects, offering additional processing capabilities and enhancing safety. They have gained popularity due to their automatic generation of unique class and animation names, alleviating concerns about selector name collisions.
