问题 Is it possible to make just the asterisk in the hint red when using a TextInputLayout from the design support library? I have seen information on styling the entire hint, but this is a little more complex since only the * should be red, not the whole message. The Material Design example shows this, but the design library doesn't seem to have any option to style it this way using a TextInputLayout and EditText.

问题 I am trying to increase the size of carousel in materialize.css but couldn't get it. I have tried setting height but it didn't work. I googled it but couldn't find any solutions.
