This is mountains.js. A JavaScript art renderer inspired by the "Mountains blue" and "Mountains Gold" images in http://parlorwall.com
Installing is simple. Include the mountains.min.js and mountains.min.css files from the latest release into your homepage, and add these five lines of HTML:
<div class="triangle triangle-blue"></div>
<div class="triangle triangle-green"></div>
<div class="triangle triangle-red"></div>
<div class="triangle triangle-yellow"></div>
<div class="triangle triangle-purple"></div>If you want to see an example usage of mountains.js, you could check out my homepage at http://liberalisten.net
Why include the HTML, instead of manipulating DOM with JavaScript? Because mountains.js provide a CSS fallback for those who have disabled JavaScript in their browser.
This also means that it isn't necessary to include the JavaScript file, but this is highly recommended since the code will make sure the abstract mountains fit perfectly on your screen.
mountains.js comes with the tools you need to make your own custom CSS, this might be handy if you for instance want to support more resolutions than the default fallback CSS provided here.
In global scope you will find a function mountainsComputeFallbackCss. This function takes as argument a comma-separated list of the different widths the fallback CSS will generate, and returns the CSS as a string.
copy(mountainsComputeFallbackCss('320,480,860,1024,1280,1920'))The above command will produce fallback CSS for six different width, and copy the result into your clipboard. The provided argument in the example above also happens to be the default values.
