CSS Question

Bootstrap navbar toggle use to add class

I use Bootstrap V3 in Wordpress.

What I want to achieve is that when someone clicks the

button
in the collapsed
navbar
menu, the
div
with the class slider gets a extra class. I'm not good with Javascript or jQeury, can you guys help me?

This is the HTML from the navbar:

<nav class="navbar navbar-default navbar-static-top">
<div class="container">
<div class="navbar-header">
<button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#navbar">
<span class="sr-only">Toggle navigation</span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
</div>
<div class="collapse navbar-collapse" id="navbar">
<?php
wp_nav_menu( array(
'theme_location' => 'navbar-right',
'depth' => 2,
'menu_class' => 'nav navbar-nav navbar-right',
'fallback_cb' => 'wp_bootstrap_navwalker::fallback',
'walker' => new wp_bootstrap_navwalker())
);
?>
</div><!-- /.navbar-collapse -->
</div><!-- /.container -->
</nav>


And this is the HTML from the
div
where I want to add a extra class:

<div class="slider">
<div class="container">
<div class="row">
other elements
</div> <!-- close row -->
</div> <!-- close container -->
</div> <!-- close slider -->


I've tried this with CSS:

.navbar-default .navbar-collapse .in ~ .slider{
margin-top: -246px;
padding-top: 176px;
}


And this with jQeury:

$(function() {
$("#navbar").click(function() {
$(".slider").addClass("sliderMove");
});
});


The extra class that should be added on slider is:

.sliderMove{
margin-top: -246px;
padding-top: 176px;
}


The purpose of this is that the slider that is after/under the
navbar
stay's under the
navbar
when it collapsed.

Answer

you were doing everything fine, but you need to use toggleClass() and select other CSS selector that is not #navbar

$(".collapsed").click(function() {
  $(".slider").toggleClass("sliderMove");
});
/* just to show in small devices */
@media (max-width: 992px) {
  .sliderMove {
    background: red;
    height: 100vh;
    width: 100%
  }
}
