Picture Magnifier

In general, the mobile phone because the screen is too small, there will be a picture of the problem, so I did a magnifying glass JS effect, support PC and mobile side. Its principle is to use the backgroundsize to achieve, so your browser first to support this property.

Then this component is also an open source Git project, and you can add a workaround for it that does not support backgroundsize.
