title: Possible to specify uneven steps in input[type=range]?
body: <p>I'd like my <code>&lt;input type="range"&gt;</code> slider to have a series of unequal increments for the <code>step</code> attribute.  Is this possible?  I'd like the values to be 100, 70, 50, 20.  Since there are unequal amounts between these values, setting <code>step</code> to a value won't work.  I haven't found any documentation about this, so I'm wondering if anyone might have a solution here.</p>
