hi,
thanks for your response, the effect of tremor in the animation pair disappeared, but not IE10 or less, according to http://www.zdnet.com/web-browser-war-the-early-2013-report-7000013354 /, ie is used by over half the world, this is a reality, according to Netmarketshare, otherwise by statcounter, because the way to get the information from both is different, most people use ie, but used q I use firefox crhome or longer, remember that web applications are generic, cross-platform, and can not tell a visitor uses this and this not, if we did that better we are dedicated to making native apps, I think I extended something.
Best regards.
