Hamburger menu on phone | button

Hello,

So I have a question to ask regarding the phone hamburger menu. I've just noticed that when someone enters my website from the link in my instagram bio and then choses to see the hamburger menu the button doesn't show unless the scroll down (which nobody will see and it will get lost). I've tried with coding to make the letters smaller but it did't work again. Is there a way to change the padding and bring everything upper? I mean there is a lot of space on the top after the logo why it has to be so long.   

Thank you in advance
