Converting React CSS styles to CSS classes

Converting React CSS styles to CSS classes is important for several reasons:

Separation of Concerns: By using CSS classes, the styling and layout of a React component can be separated from its functionality. This makes the code easier to maintain and update, as changes to the styling don’t affect the component’s behavior.

Reusability: CSS classes can be reused across multiple components, making it easier to maintain consistency in the appearance of a website or application.

Performance: Inlining styles in a React component can lead to slow performance, as the styles need to be recalculated every time the component is re-rendered. Using CSS classes instead can improve the performance, as the styles are cached by the browser.

Better Tooling: CSS class-based styles can be optimized and minified using tools such as CSS preprocessors and postprocessors, making the code more efficient and faster to load.

For example the following inline styles can be posted to chatgpt

  border: "1px solid #fff",
  paddingRight: "4px",
  paddingLeft: "4px",
  paddingTop: "5px",
  paddingBottom: "5px",
  minWidth: "75px",
  backgroundColor: "white",
  boxShadow: "0 0 2px 0 rgba(0, 0, 0, 0.5)",
  fontSize: "14px",
  textAlign: "center",

Pasting that to chatgpt, it gives me this:

.some-class {
  border: 1px solid #fff;
  padding-right: 4px;
  padding-left: 4px;
  padding-top: 5px;
  padding-bottom: 5px;
  min-width: 75px;
  background-color: white;
  box-shadow: 0 0 2px 0 rgba(0, 0, 0, 0.5);
  font-size: 14px;
  text-align: center;
}

This illustrates how simple it can be to build useful tools that boost developer productivity and make life easier for everyone.

In conclusion, converting React CSS styles to CSS classes is a best practice that can lead to better maintainability, performance, and overall organization of code.
