Load

or require it:

var Nanobar = require('path/to/nanobar');

Generate progressbar

var nanobar = new Nanobar( options );

options

id <String>: (optional) id for nanobar div
classname <String>: (optional) class for nanobar div
target <DOM Element>: (optional) Where to put the progress bar, nanobar will be fixed to top of document if no target is passed

percentage <Number> : percentage width of nanobar

Example

Create bar

var options = {
	classname: 'my-class',
  id: 'my-id',
	target: document.getElementById('myDivId')
};

var nanobar = new Nanobar( options );

//move bar
nanobar.go( 30 ); // size bar 30%
nanobar.go( 76 ); // size bar 76%

// size bar 100% and and finish
nanobar.go(100);

Customize bars

Nanobar injects a style tag in your HTML head. Bar divs has class .bar, and its containers .nanobar, so you can overwrite its values.

Default css:

.nanobar {
  width: 100%;
  height: 4px;
  z-index: 9999;
  top:0
}
.bar {
  width: 0;
  height: 100%;
  transition: height .3s;
  background:#000;
}

You should know what to do with that ;)
