React app design patterns — split layout
In a React application, when you want to establish a layout split pattern, the aim is to break down the user interface into distinct sections or components, each with a dedicated role in presenting specific content or functionality. This practice promotes the development of a codebase that is organized, reusable, and easier to manage over time. When implementing a layout split pattern in your React project, you have several options to choose from, and your decision will be influenced by the intricacy and unique demands of your project. One widely adopted approach is as follows:
- Component structure
Divide your layout into different sections or components. For example, you might have a Header, Footer, Main content area, and navigational or presentational component pieces. Each of these sections should be represented as separate React components.

2. Layout components
Develop layout components that oversee the overarching structure of your application. These components hold the responsibility of rendering the primary layout framework and arranging various sections. Depending on your requirements, employ CSS Grid, Flex-box, or any other appropriate layout techniques.

3. Content Components
Within each designated section (such as Header, Main, Footer), incorporate specific components responsible for handling respective content or functionality. For instance, within the MainContent component, consider implementing various subcomponents tailored to display diverse types of content.

4. Stylings
Apply CSS or leverage a CSS-in-JS solution to stylize your components and layout. You have the option to employ a CSS preprocessor like Sass, or you can opt for a CSS-in-JS library such as styled-components or Emotion. These choices aid in maintaining organized and easily maintainable styles throughout your application.
