CSS image stuck at the bottom - css

Question

I have this image that I'm trying to position to a certain spot, but no matter what I try the image stays a the bottom. I've been able to center the image horizontally but now I want to manipulate it vertically and get it to the top or near the top area. It baffles me how margin isn't working; how would I go by doing it?
*{
margin: 0;
padding: 0;
}
body{
height: 100vh;
background: linear-gradient(to bottom right,#e66465, #9198e5);
font-family: sans-serif;
}
.signup-forms{
background-color: #ffffff;
max-width: 350px;
margin: 5% auto;
text-align: center;
border-radius: 5px;
box-shadow: 0px 0px 25px 0 #3d3d3d6e;
padding: 20px 5px;
}
.signup-forms h3{
color: #EB4D8A;
margin-top: 20px;
}
.signup-forms p{
color: #C3BFDA;
font-weight: 600;
font-size: small;
margin-bottom: 20px;
}
.signup-input{
outline: none;
width: 75%;
background-color: transparent;
padding: 10px 5px;
border: none;
border-bottom: 1px solid #C3BFDA;
font-weight: bold;
margin: 15px;
}
.signup-input::placeholder{
color: #C3BFDA;
}
.signup-btn{
background-color: #fc4186;
color: white;
border: none;
border-radius: 3px;
width: 80%;
padding: 10px;
margin-top: 20px;
transition: 0.3s;
}
.signup-btnTwitter{
background-color: #54ACF0;
color: white;
border: none;
border-radius: 3px;
width: 80%;
padding: 10px;
margin-top: 10px;
transition: 0.3s;
}
.logo-img{
height: 60px;
width: 60px;
background-color: #fff;
border-radius: 50%;
padding: 10px;
display: block;
margin-left: auto;
margin-right: auto;
margin-bottom: 100%;
}
The image I'm trying to manipulate is .logo-img

We can't know much since there's not html code, but you can do :
`margin-top : -100px` //or how many pixels you like
or you can use the :top or bottom
Example:
top: 20%
or
bottom : 20%
or you can :
position: absolute;
z-index : 1;
