When opening modal, my main view turns black MVC - asp.net-mvc

Question

I implemented a modal window with partial view using bootstrap, the problem is that when I open my modal it leaves the main view blocked, giving it a black color
When I inspect the item with the console of my browser, I can not find the control that gives the property of the fund to the manners
Incorporate a template of Boostrapwatch for some time in my project, I enclose the code:
.modal-open {
overflow: hidden;
}
.modal {
position: fixed;
top: 0;
right: 0;
bottom: 0;
left: 0;
z-index: 1050;
display: none;
overflow: hidden;
outline: 0;
}
.modal-open .modal {
overflow-x: hidden;
overflow-y: auto;
}
.modal-dialog {
position: relative;
width: auto;
margin: 0.5rem;
pointer-events: none;
}
.modal.fade .modal-dialog {
-webkit-transition: -webkit-transform 0.3s ease-out;
transition: -webkit-transform 0.3s ease-out;
transition: transform 0.3s ease-out;
transition: transform 0.3s ease-out, -webkit-transform 0.3s ease-out;
-webkit-transform: translate(0, -25%);
transform: translate(0, -25%);
}
.modal.show .modal-dialog {
-webkit-transform: translate(0, 0);
transform: translate(0, 0);
}
.modal-dialog-centered {
display: -webkit-box;
display: -ms-flexbox;
display: flex;
-webkit-box-align: center;
-ms-flex-align: center;
align-items: center;
min-height: calc(100% - (0.5rem * 2));
}
.modal-content {
position: relative;
display: -webkit-box;
display: -ms-flexbox;
display: flex;
-webkit-box-orient: vertical;
-webkit-box-direction: normal;
-ms-flex-direction: column;
flex-direction: column;
width: 100%;
pointer-events: auto;
background-color: #4E5D6C;
background-clip: padding-box;
border: 1px solid rgba(0, 0, 0, 0.2);
border-radius: 0;
outline: 0;
}
.modal-backdrop {
position: fixed;
top: 0;
right: 0;
bottom: 0;
left: 0;
z-index: 1040;
background-color: #000;
}
.modal-backdrop.fade {
opacity: 0;
}
.modal-backdrop.show {
opacity: 0.5;
}
.modal-header .close {
padding: 1rem;
margin: -1rem -1rem -1rem auto;
}
.modal-title {
margin-bottom: 0;
line-height: 1.5;
}
I have to put some additional class in my modal window?
<div class="modal" id="myModalEditar">
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title">Editar Producto</h5>
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
</div>
<div class="modal-body" id="EditModalBody">
</div>
</div>
</div>
</div>
do I have to create another css property? What is wrong with this? any help for me?

Answer 1

It's the Bootstrap modal backdrop you'll want to hide. To do so you could add this style:
.modal-backdrop {
display: none;
}
or change the opacity:
.modal-backdrop {
opacity: 0;
}
