Modernizr library for .svg

If you use the .svg format, you must ensure that you have an alternative for browsers that do not support .svg
 

 



One technique is to use the library Modernizr
Which detects whether the browser supports .svg and if not, add a class that allows you to change the image path for a .png



CSS

.pomme {
    background-image: url('img/pomme.svg');
}
.no-svg .pomme {
    background-image: url('img/pomme.png');
}
