Wanting a smooth transition when logo disappears on scroll

I have the below code added to my site and while it is working to remove the logo on scroll the transition is harsh. Is there a way to make it smoother? Perhaps to shrink or fade out?

I would also like the logo to disappear once you hit the second black section. Is this possible? Thank you!

/* Change logo on scroll */
.shrink .header-title-logo img {
    visibility: hidden;
    transition: fade 0.3s;
}
  

Add this code under

header#header img {
	transition: all 0.3s;
}
