  18. <p>A <b>variation</b> alters the design of an element but is not mutually exclusive. Variations can be stacked together, or be used along with altering an element's type.</p>
  19. <p>For example, having wide menus that take up the full width of its parent may sometimes be overwhelming. You can use the compact variation of a menu to alter its format to only take up the necessary space.</p>

  42. <h3 class="ui header">Context sensitive</h3>
  43. <p>In Semantic, variations maintain context based on the element they modify, but keep the same vocabulary between elements. Just like how in English, the adjective 'big' may describe a different scale for a big planet versus a big insect.</p>
  44. <p>For example an icon might need to modify it's vertical alignment when it is larger than the surrounding text, while a form does not.</p>
  45. <p>All definitions in Semantic <b>are based around em and rem</b> so resizing an element usually is as simple as altering the base font size of the element, padding, margins, and other properties will adjust automatically.</p>
  46. <div class="code" data-type="css" data-label="true">
  47. /* a large form is not quite as large as a large icon */
  48. .ui.large.form {
  49. font-size: 1.125em;
  50. }
  51. /* icons need to adjust vertical alignment as they grow past 1em */
  52. i.large.icon {
  53. font-size: 1.5em;
  54. vertical-align: middle;
  55. }

  57. <h2 class="ui dividing header">Using Variations Together</h2>
  58. <p>Another variation of a menu is an <b>inverted menu</b>. This alters the color contrast to appear inverted for darker backgrounds. Some variations may also mutate when used together. Lets try adding the class name <code>red</code> as well.</p>
  59. <p>Variations are not mutually exclusive and can be used together harmoniously, so we can use these together to create an <code>inverted red tiered menu</code></p>

  83. <h3 class="ui header">Intersecting Variations</h3>
  84. <p>The definition for the variation red contains css specifically for describing the intersection of both <code>red</code> and <code>inverted</code>. For example, lets see the same menu with only the red variation.</p>
