How to make the asterisk in the placeholder red, please tell me.

Answer 1

Many variations:
1. Wrap the input in a label and style an asterisk through after for the label
2. Different masks, there are default ones, but you need to look for such plugins, not all masks have stars
3. Through the span after the input and position it so that it stood right in the field
