Bootstrap 3 dropdown menu changing background on submenu focus - html

Question

I have changed the background colors of my Bootstrap menu, but the background color of the main dropdown item in the list is changing when the submenu (the menu that opens up when the dropdown item is clicked) is in focus (ie my mouse is over it).
This is the dropdown on hover (which is behaving as intended):
This is the dropdown when I have my mouse over the submenu that opens when the dropdown is clicked (the background color is not what I want; I want the background color to remain the same):
Here's the HTML:
<li class="dropdown">
<a href="#" class="dropdown-toggle" data-toggle="dropdown">
Dropdown <b class="caret"></b>
</a>
<ul class="dropdown-menu">
<li>Action</li>
<li>Another action</li>
<li>Something else here</li>
<li class="divider"></li>
<li class="dropdown-header">Nav header</li>
<li>Separated link</li>
<li>One more separated link</li>
</ul>
</li>
And the CSS:
.navbar-mainnav {
background-color: #883333;
background-image: none;
}
.navbar-mainnav a, .navbar-mainnav a:hover {
color: #FFFFFF;
}
.navbar-mainnav .navbar-nav > .active > a, .navbar-nav > .active > a:hover, .navbar-nav > .active > a:focus {
color: #ffffff;
background-color:transparent;
}
.navbar-mainnav .nav > li > a:hover, .mainnav > li.dropdown.open {
background-image: none;
background-color: #B54646;
}
.navbar-mainnav .dropdown-menu > li > a:hover, .navbar-mainnav .dropdown-menu > li > a:focus {
background-color: white;
background-image: none;
filter: none;
}
.navbar-mainnav .dropdown-menu > li > a:hover {
background-color: #CC6666;
background-image: none;
}

Answer 1

Just put this css i think this is worked
.navbar .nav li.dropdown.open > .dropdown-toggle, .navbar .nav li.dropdown.active > .dropdown-toggle, .navbar .nav li.dropdown.open.active > .dropdown-toggle {
background-color: #B54646;
}

Answer 2

Maybe try this? Please post a jsfiddle so we can make sure it works.
.navbar-default .navbar-nav > li:hover {
background: #your-background-color;
color: #your-text-color;
}

Answer 3

Here's a working fiddle : https://jsfiddle.net/Lindow/yvyvg1ja/4/
To prevent the background from changing on dropdown click use :
.navbar-default .navbar-nav > .open > a, .navbar-default .navbar-nav > .open > a:focus, .navbar-default .navbar-nav > .open > a:hover {
background-color: #CC6666;
}

Answer 4

You need to style anchor tag children of the .open class, along with :hover and :focus states like so:
.navbar-mainnav .nav .open>a,
.navbar-mainnav .nav .open>a:focus,
.navbar-mainnav .nav .open>a:hover {
background: #B54646;
color: #fff;
}
Run the code snippet in full page to see how it works.
.navbar-mainnav {
background-color: #883333;
background-image: none;
}
.navbar-mainnav a, .navbar-mainnav a:hover {
color: #FFFFFF;
}
.navbar-mainnav .navbar-nav > .active > a, .navbar-nav > .active > a:hover, .navbar-nav > .active > a:focus {
color: #ffffff;
background-color:transparent;
}
.navbar-mainnav .nav > li > a:hover, .mainnav > li.dropdown.open {
background-image: none;
background-color: #B54646;
}
.navbar-mainnav .dropdown-menu > li > a:hover, .navbar-mainnav .dropdown-menu > li > a:focus {
background-color: white;
background-image: none;
filter: none;
}
.navbar-mainnav .dropdown-menu > li > a:hover {
background-color: #CC6666;
background-image: none;
}
.navbar-mainnav .nav .open>a,
.navbar-mainnav .nav .open>a:focus,
.navbar-mainnav .nav .open>a:hover {
background: #B54646;
color: #fff;
}
