steroid and ionic css compatibility?

by default steroids uses ionic for it's css framework.

Testing today it looks like i get very different results on 2 different android devices

Galaxy s2 – i9100 running android 4.4.2

Galaxy Tab – P7500 running android .2.2

My questions are:

• is this expected?

• if no, is there any idea what i might be doing wrong? are there different config files between android tablet/phone?

• if yes, is there another css framework people know of that might give me more consistent results across devices?!
