screen-responsive navbar can't work properly

I have navigation bar for pc and for mobile, problem is if I maximize window when mobile navbar is opened, mobile navbar will disappear as it should but desktop navbar doesn't appear. I am working with bootstrap template and I don't know if my problem solution requires javascript knowledge but if it does, I can show it.
Here is my css code
/**

.navbar {
padding: 0;
}
.navbar ul {
margin: 0;
padding: 0;
display: flex;
list-style: none;

.navbar a,
.navbar a:focus {

}

Can a header slide under a sticky navbar?

I want the heading to "slide" along under the navbar. But now it looks like the picture.
I have just started and would be very happy about some support. I already have some experience with HTML and CSS but now I don't know what to do.
My goal is to have the heading slide under the navbar.
sorry for the long CSS:)

Issues with using Active class in Bootstrap

Currently, the ‘Active’ class is seen on the FAQ and it creates a misleading impression Example. As of now, the hovering still exists in White. I want to achieve where An active element will be in White and display accordingly when the user clicks Example. I have provided my .html and .css, however, the provided snippet output is inaccurate. Please use your preferred software such as Visual Studio, etc. Thank you.

Update 1
The following result is correct https://ibb.co/phP4c8d, however how do I make it White for the remaining elements? It's something like this https://codepen.io/gearmobile/pen/bByZdG. Correct me if I'm wrong but I believe it requires a JavaScript.

i dont know if i understood your question but i think what you want is this,
#sidebar ul li.active>a,
a[aria-expanded="true"] {
color: #6d7fcc;
background: #fff;
}

Bootstrap sidebar and page content are merged

I am attempting to use a bootstrap sidebar which on smaller screens becomes horizontal navigation. Everything is working fine except for Page content (which has to be on right side of sidebar) appears on top of sidebar.

<h1>Simple Sidebar</h1>
<p>This template has a responsive menu toggling system. The menu will appear collapsed on smaller screens, and will appear non-collapsed on larger screens. When toggled using the button below, the menu will appear/disappear. On small screens, the page content will be pushed off canvas.</p>
<p>Make sure to keep all page content within the <code>#page-content-wrapper</code>.</p>

UPDATE: As suggested added padding to page-wrapper, but when I add text to page content, sidenav links stop working/hovering.
JS FIDDLE https://jsfiddle.net/y3eL6m8v/4/

In the media query you should add a padding-left with the value of the width from the sidenav to the page-content-wrapper class.
#media(min-width:768px) {
#page-content-wrapper {
padding-left: 250px;
position: relative;
}
}

Please add this in your css:
#media (min-width: 768px)
{
#page-content-wrapper
{
padding: 20px 20px 20px 250px;
position: relative;
}
}

How to show the titles properly in an expandable menu?

I'm trying to do a expandable menu in jQuery and CSS3, here is the fiddle:
http://jsfiddle.net/mNcuQ/3/
When you click the slidebar, the titles section is showed. But I'm afraid it doesn't look properly. What I'm trying to do is when the .expanded class is active and the width of the slidebar is modified ( with the transition finished ) then show the titles of the menu with fade in effect. As I do now, the titles of the menu are not respeting the display: inline-block. Surely I'm missing something...
Do you have any idea or tip to do it? What is better to use in this case: CSS3 transition or jQuery animation?
Here is the code of the fiddle:
HTML
<div id="sidebar">
<a class="btn-navbar" data-toggle="collapse" data-target=".nav-collapse">
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</a>
<nav id="nav" class="navigation" role="navigation">
<ul class="unstyled">
<li class="active" data-section="1"><i class="icon-home"></i> <span>Home</span>
</li>
<li data-section="2" class=""><i class="icon-rocket"></i> <span>Services</span>
</li>
<li data-section="3" class=""><i class="icon-laptop"></i> <span>Projects</span>
</li>
<li data-section="6" class=""><i class="icon-money"></i> <span>Price</span>
</li>
<li data-section="4" class=""><i class="icon-pencil"></i> <span>Team</span>
</li>
<li data-section="5" class="last"><i class="icon-envelope"></i> <span>Contact</span>
</li>
</ul>
</nav>
</div>

$('html').toggleClass('expanded');

If you need more info, let me know and I'll edit the post.

use transition-delay maybe?
Fiddle (moved revelant css classes to bottom)
#nav li span {
display: inline-block;
font-size: 14px;
font-size: 1.4rem;
height: 0;
opacity: 0;
overflow: hidden;
padding-left: 10px;
width: 0;
transition:opacity 0.5s ease; // ease opacity
}
.expanded #nav li span {
display: inline-block;
height: auto;
opacity: 1;
overflow: visible;
width: auto;
transition-delay: 500ms; //delay transition by the same amount of sidebar width transition time
}

the problem is that you expanded container is too small to position the headlines correct, make it a bit larger and it will work
.expanded #sidebar {
width: 180px;
}
