Placeholder design

Hello,

I’m at 2nd front end development project and i dont know how to change the font-size and font-family of my Placeholder in a input box.

Can someone help me?

Can you link to your codepen?

Here is my pen: https://codepen.io/GPorto/pen/NyMxbQ

I solved my problem when i changed my input font-size

#contato input { margin-top: 30px;
width: 100%;
height: 50px;
font-size: 30px;
background-color: white;}

But in the Msg input box, the text “Digite sua mensagem” is at input box middle, how can i move it to the top?

Thank you for the answer about the size
