Blocks
How This All Works
CardView1 carries Hint Label (Label1).
OverlapView Block Overlaps the CardView1 on CardView2 making the whole Raised Hint Design.
And the ContentPaddingTop Property of CardView2 Helps in Keeping CardView1 Level of Rise Correct to the Required Point.
CardView3 StrokeColor and StrokeWidth sets the BorderColor and BorderWidth of TextBox.

This method is not exclusively for the TextBox Design.
You can use the same Method to Overlap Any Component over the Other.

NOTE
-
To Change the Right Margin -
According to your Needs, just Icrease or Decrease this value
-
if we change the Hint Label (Label1) FontSize,
We also need to change theContentPaddingTopProperty of CardView2 accordingly.
Use Hit and Trial until you feel /observe that the Hint Label (CardView1) raised to the Desired Level.
