They are known as 'Floating labels / placeholders'. And they are based on Material Design . It is a type of design with certain standards created by Google.

There are several ways to do it and that varies from developer to developer, I leave you one way. You just need to put your own styles.

input[type="email"][required]:focus + label[placeholder]:before,
form select[required]:focus + label[placeholder]:before
