How to my toggle button change color only my collapse is opened in my bootstrap 3 navbar

Question

When we open collapse, button change color. but when we closed collapse by button click, the button doesn't return to its initial color. Button is focused. And I want that lost the focus.

I have tried with css :focus, but it didn´t lose focus after collapse have been closed by button. I think that jquery function is necessary, although I've tried, my js skills shouldn't be sufficient.

I need help please

    }

    $('html').click(function (event) {
        var clickover = $(event.target);
        var _opened = $(".navbar-collapse").hasClass("navbar-collapse in");
        if (_opened === true && !clickover.hasClass("navbar-toggle")) {
            CloseNav();
        }

    });

Hi the problem here is with the focus state of the button once you click it never loses the focus unless you click outside again. You can try this:

First make a class that replicates the hover and focus state for the button:

.highlight {background:#ddd}

Then you can modify your Jquery to force the button lose his focus state on click and apply the class to keep the visual effect:

$('.navbar-toggle').click(function() {
      $(this).toggleClass('highlight').blur();
});

Also since your collapse close every time you click outside the button you need to add some there:

if (_opened === true && !clickover.hasClass("navbar-toggle")) {
     $('.navbar-toggle').toggleClass('highlight'); /**Add This**/
     CloseNav();
}
