2R - CSS Nesting

Created by AI

Selector Nesting

1. In traditional CSS, selectors are independent and apply styles globally. However, with nesting, you can define styles for child elements within the context of their parent’s style rule.
2. For example, consider this nested selector:
3. .parent {
   background-color: lightblue;
   font-size: 16px;
   /* Nested child selector */
   .child {
   color: darkblue;
   }
   }
4. Here, the .child selector inherits styles from its parent .parent.

Readability and Maintainability

1. Nesting promotes readability by encapsulating related styles together.
2. It makes your code more modular, allowing you to organize styles logically.
3. When you revisit your stylesheet, nested rules help you quickly understand the structure.

Browser Parsing vs. Preprocessors

1. Unlike CSS preprocessors (e.g., Sass), where nesting is pre-compiled, native CSS nesting is parsed directly by the browser.
2. This means that the browser understands and applies the nested rules without any pre-processing step.

Specificity Considerations

1. When nesting, be aware of specificity. The child selector inherits the specificity of its parent.
2. For instance, if both .parent and .child have conflicting styles for the same property, the child’s specificity takes precedence.

Example Button

1. In this example I created a button with a class called rd-button. I then styled it to make it more like a button.
2. I used the & to created a hover on the nested class to use when the button is hovered.
3. I could use nesting to help organize my code and make it easier to edit and understand what is happening in each section
