Responsive#

Spectre provides a neat responsive layout grid system and responsive visibility utilities.

There are col-xs-<1-12>, col-sm-<1-12>, col-md-<1-12>, col-lg-<1-12> and col-xl-<1-12> available for flexible grid across mobile, tablet and desktop viewport usage.

• col-xs-<1-12> apply to window width smaller than or equal to 480px.
• col-sm-<1-12> apply to window width smaller than or equal to 600px.
• col-md-<1-12> apply to window width smaller than or equal to 840px.
• col-lg-<1-12> apply to window width smaller than or equal to 960px.
• col-xl-<1-12> apply to window width smaller than or equal to 1280px.
• col-<1-12> apply to all window width, including the width wider than 1280px.

<div class="container">
  <div class="columns">
    <div class="column col-xs-6">col-xs-6</div>
    <div class="column col-xs-3">col-xs-3</div>
    <div class="column col-xs-3">col-xs-3</div>
  </div>
</div>

Responsive container#

The responsive layout also provides fixed-width containers. Use grid-xs(480px), grid-sm(600px), grid-md(840px), grid-lg(960px) or grid-xl(1280px) to the container for a fixed-width container with the specific max-width.

<!-- 100% width container with max-width set to grid-lg (960px) -->
<div class="container grid-lg">
  <div class="columns">
    ...
  </div>
</div>

Responsive visibility#

The responsive visibility utilities help show and hide elements on specific viewport sizes.

For hiding elements on specific viewport sizes, there are classes hide-xs, hide-sm, hide-md, hide-lg and hide-xl available.

• hide-xs hides elements when the window width is smaller than or equal to 480px.
• hide-sm hides elements when the window width is smaller than or equal to 600px.
• hide-md hides elements when the window width is smaller than or equal to 840px.
• hide-lg hides elements when the window width is smaller than or equal to 960px.
• hide-xl hides elements when the window width is smaller than or equal to 1280px.

For showing elements on specific viewport sizes, there are classes show-xs, show-sm, show-md, show-lg and show-xl available.
