更改 Bootstrap 4 下拉按钮 Colors

Question

I'm trying to change the buttons' colors, but I only managed to change the colors when hovered so far.

Here is my HTML and this is my CSS when it changes color by hovering::

 .nav > li > a:focus, .nav > li > a:hover { background-color: #00AEFE; }

Answer 1

To change the general color, delete the:focus and the:hover (only active when focused or hovered)

.nav > li > a{
   background-color: #00AEFE;
}

Even better:

.navbar-toggle {
     background-color: #00AEFE;
}

Note: This only changes the style of the element containing "navbar-toggle" in class
