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.
Whenever one object exerts a force on a second object, the second object exerts an equal and opposite force on the first object. Describes the relationship between two forces in an interaction. One force is called the action force. The other force is called the reaction force. Neither force exists without the other.
