Responsive Web Design

Ethan Marcotte coined the term 'responsive web design'.
The core tenets of Responsive Web Design are: flexible grids, flexible images, and media queries.

Web Development

Optimizing for mobile first in web development is beneficial because it allows for a more focused and efficient design process.
Flex items in a Flexbox container behave based on their initial behavior, and can change layout depending on the available space.

CSS
