Ok, ich hab es jetzt so gemacht und es geht, keine Ahnung ob es richtig ist

  
section.small-features img {  
		width:32.2%;  
		height:auto;  
		padding-right:1%;  
		margin-top:2%;  
}  
  
section.small-features img:nth-of-type(3n) {  
		padding-right:0px;  
	}  
  
  
  
@media screen and (max-width: 720px) {  
	section.small-features img {  
		width:49%;  
		height:auto;  
		padding-right:1%;  
		margin-top:2%;  
}  
  
section.small-features img:nth-of-type(3n) {  
		padding-right:1%;  
	}  
  
	section.small-features img:nth-of-type(2n)  {  
		padding-right:0;  
	}  
  
}  
  
@media screen and (max-width: 430px) {  
	section.small-features img {  
		width:100%;  
		height:auto;  
		margin-top:2%;  
}  
}
