Okay - well I have a code example here that does both. It’ll be easy to modify it to fit your situation.https://jsfiddle.net/ukfay4do/

CSS is used to achieve this:

I am interested in your view on the compatibility of the proposed solution. After reading about the CSS transform rule I find that it is listed as experimental, as detailed in the following link.
MDN

I also find that the JSFiddle example shown here throws errors in IE7 and IE8. Would you say that this solution is suitable for production, or should it be flagged “user beware”?

I feel that this is something that is best determined by the person receiving the advice. If they are using the code for production work, it is normally expected that the people putting it into production are aware of compatibility issues and that ie8 usage is at 5%

Having said that though, it is important that issues of compatibility and usability are covered too.
