Lightning fast responsive web development

Responsive from the ground up

Our grid system is percentage based. Nesting grid elements gives you infinite possibilities. Version 3.0.0 introduces a flex based grid system that gives you unprecedented control over your layouts.

<div class="ink-grid">
  <div class="column-group">
    <div class="all-50 small-100 tiny-100">...</div>
    <div class="all-50 small-100 tiny-100">...</div>

Easy to code and easy to read

Our syntax was designed to be clean and readable like a human language, creating legible code that both designers and developers can understand, helping to make your work accessible to anyone on your teams.

<nav class="ink-navigation">
  <ul class="horizontal menu">
    <li><a href="/home">home</a></li>
    <li><a href="/about">about</a></li>

More than HTML and CSS

We've developed our own JavaScript library based on the latest coding standards and a modular architecture. The Ink.requireModules() method ensures all of Ink's power is at your fingertips.

  function(Css) {
    var elm = Ink.s('.ink');


Ink's CSS is created with SASS. Breakpoints, dimensions, color, font sizes and even class names are defined as variables and are easily reconfigurable. Just edit a couple of files, recompile and you'll have your unique custom build.

// scss
$ink-class-prefix: my-;
$navigation-class-name: #{$ink-class-prefix}nav
// css
.my-nav {
