regardless of technology, you could do this only with media querys in css, I’ll post an example for you functional:
@media (min-width:320px) { /* smartphones, iPhone, portrait 480x320 phones / }
@media (min-width:481px) { / portrait e-readers (Nook/Kindle), smaller tablets @ 600 or @ 640 wide. / }
@media (min-width:641px) { / portrait tablets, portrait iPad, landscape e-readers, landscape 800x480 or 854x480 phones / }
@media (min-width:961px) { / tablet, landscape iPad, lo-res laptops ands desktops / }
@media (min-width:1025px) { / big landscape tablets, laptops, and desktops / }
@media (min-width:1281px) { / hi-res laptops and desktops */ }
iphone
@media only screen and (min-device-width: 480px){}
ipads or tablets
@media only screen and (min-device-width: 768px){}
