## What it is
Unsemantic is a fluid, percentage-based CSS grid framework and successor to the 960 Grid System, built with Sass. It provides responsive grid classes (grid-5 through grid-100, plus push/pull helpers) with mobile, tablet, and desktop breakpoints via media queries or Adapt.js.

## Use cases
- build a responsive percentage-based page layout
- replace the 960 Grid System with a fluid grid
- create mobile, tablet, and desktop breakpoints for a grid
- reorder page content visually with push and pull classes for SEO
- generate custom grid class names using Sass placeholders and mixins
- support legacy browsers like IE7 in a responsive layout

## When to choose
- you want a lightweight, percentage-based fluid grid without a full CSS framework
- you need to modernize an existing 960.gs layout
- you prefer Sass mixins/placeholders to emit only the CSS you need
- you must support very old browsers such as IE7

## When to avoid
- you are starting a modern project where CSS Grid or Flexbox is available
- you need a full design system with components, not just a grid
- you want an actively developed framework with recent updates
- you rely on utility-first frameworks like Tailwind CSS
