Responsive

Is there a way that we can make a tagul cloud responsive, so that it appears good on mobile devices as well?

Just make the div container's (which includes script tag) width and height in "%" instead of "px", e.g.:

<div style="width: 100%; height: 100%; border: 1px solid silver;padding-bottom: 30px;">

Then your cloud should be resized accordingly when browser window is resized.
