Readme
Floating labels display the type of input a field requires. Every Text Field and Select should have a label, except for full-width text fields, which use the input's placeholder
attribute instead. Labels are aligned with the input line and always visible. They can be resting (when a field is inactive and empty) or floating. The label is a text caption or description for the Text Field.
npm install @material/floating-label
