Building Molecules and Organisms in Figma
Key Concepts
- Atoms: The smallest, indivisible components of a design system.
- Molecules: Groups of atoms bonded together to form a more complex, yet still simple, component.
- Organisms: Groups of molecules joined together to form distinct sections of an interface.
Atoms
Atoms are the basic building blocks of any design system. They include elements like buttons, input fields, and icons. These are the smallest, indivisible components that cannot be broken down further without losing their meaning.
For example, a button is an atom. It consists of a background color, text, and sometimes an icon, but it functions as a single, complete element.
Molecules
Molecules are groups of atoms bonded together to form a more complex, yet still simple, component. They are the next level of abstraction and are often used to create reusable, modular components.
For example, a search bar is a molecule. It consists of an input field (atom) and a search button (atom) combined to form a functional unit that can be reused across different parts of a website.
Organisms
Organisms are groups of molecules joined together to form distinct sections of an interface. They are more complex and represent larger, more meaningful components of a design system.
For example, a header section of a website is an organism. It might include a logo (molecule), navigation menu (molecule), and search bar (molecule) combined to form a cohesive, functional section of the interface.
Examples and Analogies
Think of atoms as the individual LEGO bricks. Molecules are the combinations of these bricks to form simple structures like a door or a window. Organisms are the larger structures like a house, which are made up of multiple doors, windows, and other components.
Another analogy is that of a kitchen. Atoms are the individual utensils like knives and forks. Molecules are the combinations of these utensils to form a set, like a dinner set. Organisms are the entire kitchen setup, including multiple sets of utensils, appliances, and storage units.
