In the context of design and development, a "framework" refers to a suite of tools, libraries, conventions, and attempts to abstract reusable common modules from routine tasks. The goal is to enable designers and developers to focus on the unique aspects of their projects, avoiding the need to reinvent the wheel. Generally speaking, frameworks often refer to commonly used JavaScript frameworks and web application frameworks. Of course, there are also CSS frameworks (such as an introduction to 15 CSS frameworks and Typogridphy: a CSS framework suitable for grid layouts, along with the 960 Grid System used for grid-based designs).
