So you can tweak the positional difference between the placeholder text and value simply by tweaking the padding or line-height using that pseudo-element selector: input[type=text] { padding:4px; } input[type=text]::-webkit-input-placeholder { padding-top:5px; } Or whatever.
Identifying and describing action-reaction force pairs is a simple matter of identifying the two interacting objects and making two statements describing who is pushing on whom and in what direction. For example, consider the interaction between a baseball bat and a baseball.
Clearly, the drag force has a big effect on a baseball; losing about 10 percent of the initial speed is a big deal. On the other hand, the effect of the drag force is always the same: to delay the ball's arrival at the plate and cause it to drop a bit.y the time it reaches the plate, the fastball in air isn't moving 90 mph any more. Its horizontal speed is about 80 mph, so a 90 mph fastball loses about 10 mph due to air resistance by the time it reaches the batter.
