or in React:
<img src="xxx" style={{ zoom: '50%' }} />

I found another lib, and modified it to supoort zoom styles.

sheng-di/zooming@57f72a8 I found another lib, and modified it to supoort zoom styles.

@sheng-di I make a plugin depending this your lib, but only effect in first page or after I refresh the current page. Do you have some resolutions?
