thx I succeed it! can I move the position of the title and tagline?

What position do you mean? top,bottom or left,right?

I want it a bit more up,top! thx

Add this below style by any way.

#title {
	padding: 120px 0 0 !important;
}
@media screen and (max-height:570px) {
	#title {
		padding: 40px 0 0;
	}
}

Change 120px and 40px
