I am thinking about the 马 character. I know that when you use 土 and 车 on the left in a composed character (like 地，场... and 较，辆 ...) the 3rd stroke in 土， and the 4th in 车 change from 一 héng to ㇀ tí.
My question is: does that change also apply to the 马 character when used as the left component, as in e.g. 骑?
Is there any website where the strokes are identified correctly in accordance with Chinese standards?
