Unbelievable Breadth

Definitions aren't limited to just buttons on a page. Semantic's components fall into four categories, elements, collections, modules, and views which cover the gamut of interface design.

Accordion

<%- @partial('examples/accordion') %>

Step

<%- @partial('examples/step') %>

Input

<%- @partial('examples/input') %>

Label

<%- @partial('examples/label') %>

Message

<%- @partial('examples/message') %>

Card

<%- @partial('examples/card') %>

Feed

<%- @partial('examples/feed') %>

Dropdown

<%- @partial('examples/dropdown') %>

Segment

<%- @partial('examples/segment') %>

Checkbox

<%- @partial('examples/checkbox') %>

Simplify Your Codebase

Semantic's design is based around common usage, using features of natural language like, plurality, tense, and word order to make your code self-explanatory.
