Responsive Navigation Not Showing All Items

Hello I am currently learning responsive design and I am trying to make a responsive navigation bar which turns in to a menu when visited on a phone or mobile device! Everything works except not all the navigation items show on the mobile device and I am not sure why! This is the code:
<div class="container">
<div class="navbar">
<ul style="padding-left: 0px;">
<li class="logo"> RONNIE<b>GURR</b></li>
<section class="div_navbar_items">
<li class="navbar_items"> HOME </li>
<li class="navbar_items"> ABOUT US </li>
<li class="navbar_items"> GALLERY </li>
<li class="navbar_items"> SHOP </li>
<li class="navbar_items"> CONTACT </li>
</section>
<li class="icon">
☰
</li>
</ul>
</div>
</div>
<script src="js/responsive.js"></script>
Here is the CSS:
.container {
margin: auto;
width: 90%;
}
.navbar {
position: fixed;
z-index: 100;
overflow: hidden;
margin: auto;
width: 100%;
left:0;
top:0;
}
.navbar li.logo,
.navbar li.navbar_items {
list-style-type: none;
display: inline-block;
}
.navbar li a {
margin-top: 50px;
font-family: 'Cabin', sans-serif;
font-size: 1.3em;
color: white;
font-weight: 700px;
display: inline-block;
text-align: center;
padding: 10px 16px;
text-decoration: none;
}
.navbar li.navbar_items a:hover {
border-bottom-style: solid;
border-bottom-color: white;
/* padding-bottom: 5px; */
}
.navbar li.icon {
display: none;
}
.div_navbar_items {
float: right;
padding-right:1%;
}
/*Start of mobile nav*/
#media screen and (max-width:875px) {
.navbar li.navbar_items {
display: none;
}
.navbar li.icon {
float: right;
display: inline-block;
position: absolute;
right: 0;
top: 19px;
}
}
#media screen and (max-width:875px) {
.navbar.responsive {
position:fixed;
width: 100%;
height: 100vh;
background-color: rgba(236,201,205, 1);
transition: background-color .6s;
}
.navbar.responsive li.logo {
floatL: left;
display: block;
}
.navbar.responsive .div_navbar_items {
float: none;
padding-right:0;
}
.navbar.responsive li.navbar_items {
display: block;
padding: 50px;
font-size: 25px;
}
.navbar.responsive li.navbar_items a {
display: block;
text-align: center;
}
.navbar.responsive li.navbar_items a:hover{
color:#17171e;
border-bottom-color: transparent;
}
}
/*End of mobile nav*/
And here is the JS:
function navBarFunction() {
document.getElementsByClassName("navbar")[0].classList.toggle("responsive");
}
codepen: https://codepen.io/anon/pen/JyEoWY

I think this will get you in the right direction, then you can decide upon what you'd like to do from here. You are setting your navbar to be 100vh, which is 100% height of the screen, so you need to make sure your padding and margin on your nav elements aren't so much. Try removing any margin and padding from these two styles, then adapt it on your own from here. If you don't want to change this stuff, refer to the second part of my answer, and just make the nav scrollable.
.navbar li a {
margin-top: 0px;
}
#media screen and (max-width: 875px) {
.navbar.responsive li.navbar_items {
display: block;
padding: 0px;
font-size: 25px;
}
}
Also, if you look in .navbar styling (line 8 of your codepen) you have it set to overflow: hidden. You can update your .navbar.responsive class with overflow of scroll to get it to work.
#media screen and (max-width:875px) {
.navbar.responsive {
position:fixed;
width: 100%;
height: 100vh;
background-color: rgba(236,201,205, 1);
transition: background-color .6s;
overflow: scroll; // Set overflow to scroll
}
}

I guess this happenes because you make .navbar.responsive {
position:fixed;
And you just can't watch all content of block, because it's not allow to scroll. When i change this property to absolute, i looked all items of menu.
By the way, you write CSS property font-weight with px, font-weight: 700px, but it shouldn't be px, it's relative value: font-weight: 700

Which class should I change to make my menu margin different than text from menu items

my menu and menu items content look like this:
http://imgur.com/hvnp8YQ
When you click on menu item, the green panel slides up and show text; menu items and content are connected in JavaScript.
I want to change some class to make green panel show lower than menu items.
.menu ul {
float: right;
}
.menu ul li {
background: #161616;
list-style-type: none;
display: inline-block;
margin: auto;
color: #f7f7f7;
padding: 5px 5px 5px 5px;
font-family: 'Dosis', sans-serif;
cursor: pointer;
}
.menu ul li:not(.active):before {
content: "";
display: block;
width: 0%;
color: #f7f7f7;
border-top: 1px solid transparent;
border-image-slice: 1;
transition: width .3s ease-in-out 0s;
margin-bottom: 5px;
}
.menu ul li:not(.active):focus:before,
.menu ul li:not(.active):hover:before {
color: #f7f7f7;
border-top: 1px solid transparent;
border-image: linear-gradient(to right, #529ecc, #9CF5A6);
border-image-slice: 1;
width: 100%;
}
.menu .panel {
display: none;
background: #33b1a2;
padding: 30px;
width: 50%;
}
.menu .panel.active {
display: block;
width: 50%;
}
.active {
color: #f7f7f7;
border-top: 1px solid transparent;
border-image: linear-gradient(to right, #529ecc, #9CF5A6);
border-image-slice: 1;
margin-bottom: 5px;
}
<div class="menu">
<ul class="main">
<li rel="onas" class="active">
O NAS
</li>
<li rel="zajmujemysie">
ZAJMUJEMY SIĘ
</li>
<li rel="oferta">
OFERTA
</li>
</ul>
<div id="onas" class="panel active">
O NAS - ...
</div>
<div id="zajmujemysie" class="panel">
ZAJMUJEMY SIĘ - ...
</div>
<div id="oferta" class="panel">
OFERTA - ...
</div>
</div>
It doesn't matter which class I change, green panel and menu items shows always in the same line.

Add clear: both to the div with the id of 'onas':
#onas {
clear: both;
}
This clears the floats and ensures that the onas div will be placed below the menu.

How to apply css rules for hidden submenu?

How to apply the css rules for hidden submenu? I've tried to add some JS, but there is a problem as it doesn't work.
Below there are the samle of the code I work about. Idea is that on the click to anchor text 'A' it should be shown a submenu. Thanks in advance for any advices.
var sub=document.querySelector("#subBox"),
subToggle=document.querySelector("#submenu");
if (subToggle){
subToggle.addEventListener("click",
function(e){
if(sub.className=="open"){
sub.className="";
}else{
sub.className="open";
}
e.preventDefault();
}, false );
}
body {
background: #fff;
font-family: 'Verdana', sans;
color: #fff;
text-align: center;
}
#media only screen and (max-width:768px){
body{font-size:16px;}
}
#media only screen and (min-width:769px){
body{font-size:32px;}
}
ul li{list-style-type: none;}
li{display:inline;}
a, li a{
text-decoration: none;
outline: none;
color:#fff;
}
#menu{
width:100vw;
height:100vh;
display:block;
position:absolute;
top:0;
left:0;
background:#eacebe;
overflow:hidden;
}
#subBox{

You were close. You're applying the .open class to #subBox, so change your selector to #subBox.open.
var sub=document.querySelector("#subBox"),
subToggle=document.querySelector("#submenu");
if (subToggle){
subToggle.addEventListener("click",
function(e){
if(sub.className=="open"){
sub.className="";
}else{
sub.className="open";
}
e.preventDefault();
}, false );
}

Additional Navigation bar on click

I have a navigation bar with the section "Contracts" and I was wondering if it were possible, and how would I go about adding an additional navigation bar to expand underneath when this button is tagged, (For example, on the Apple Store site, when you click a product, this adds another bar)
I can provide my entire CSS style sheet if needed! I think this will require JavaScript but I'm trying to keep it as pure CSS for now!
All help is greatly appreciated!
HTML Code: This is the Navigation HTML
<header>
<div class="title">
<img src="img/logo2.png"/>
</div>
<div class="navbar">
<ul>
<li style="float: left">Home</li>
<li>Contracts</li>
<li>About Us</li>
<li>Other</li>
<li> Release Notes</li>
<li> <a target="_blank" href="http://www.phpartnership.com">Pinnacle Health Partnership</a></li>

This is the JavaScript I tried to use to hide and show the div on click
<script>
$(index.php).ready(function(){
``$("#contract").click(function(){
$("<div class="contracts">").toggle();
});
});
</script>

guess you want smth like this : jsfiddle
first add jQuery to your local environment
use this <script type="text/javascript" src="http://code.jquery.com/jquery-latest.min.js"></script>
add it in the head section of your html. for more info check how to install jQuery
added html inside the .navbar
<ul class="aditional">
<li>test1</li>
<li>test2</li>
<li>test3</li>
<li>test4</li>
</ul>
added css :
.aditional {
position:absolute;
top:100%;
width:100%;
background:#000;
display:none;
}
.aditional li {
color:#fff;
}
added js :
$('.navbar ul li:nth-child(2) a').click(function() {
$(".aditional").slideToggle()
});
OR if you want a more responsive solution
check this :jsfiddle with target
use data-target on the li a like this
<li>Contracts</li>
<li>About Us</li>
added html :
<ul class="aditional contracts">
<li>test1</li>
<li>test2</li>
<li>test3</li>
<li>test4</li>
</ul>
<ul class="aditional aboutus">
<li>about</li>
<li>about</li>
<li>about</li>
<li>about</li>
</ul>
jq added :
$('.navbar ul li a').click(function() {
$(".aditional").slideUp()
var target = '.' + $(this).data('target');
$(target).slideDown();
})
OR u can target the href of the li a. simply add this
<li>Contracts</li>
<li>About Us</li>
------
<ul class="aditional" id ="contract">
....
<ul class="aditional" id ="about">
....
and js :
$('.navbar ul li a').click(function() {
$(".aditional").slideUp()
var target = $(this).attr('href');
$(target).slideDown();
})
see here jsfiddle
one of these solutions should work for you . let me know

How to toggle the contents of span when clicked?

I have a navigation bar with a drop down menu. I have a + in front of the drop down menu inside a span. I would like the the plus to toggle to - when the menu is dropped down and back to + when the menu is up(hidden). How can I do this?
my html looks like
<nav>
<ul>
<li>Home</li>
<li>About</li>
<li class="shop"><span>+</span>Shop
<ul class="shopList">
<li>New Arrivals</li>
<li>Dresses</li>
<li>Jumpsuits</li>
</ul>
</li>
<li>Wholesale</li>
<li>Retailers</li>
<li>Contact</li>
</ul>
</nav>
I am currently using js to drop down my menu. Can I add to my current js to achieve this. My js looks like
$(document).ready(function() {
$('.shop').click(function() {
$('.shopList').slideToggle("fast");
});
});
here is my css
nav{
position:relative;
display:block;
width:70%;
margin:0;
padding:3px 15%;
border-top:1px solid #d0d0d0;
text-align:center;
font:15px 'OpenSans';
z-index: 999;
}
nav ul{
position:relative;
width:100%;
margin:0;
padding:0;
}
nav li{
display:inline-block;
margin:0 10px;
padding:0;
}
nav li ul li{
position:relative;
display:block;
width:150px;
margin:0;
padding:0;
}
.shopList{
position:absolute;
display:none;
width:100px;
margin:0 0 0 -50px;
padding:0;
}
nav a{
position:relative;
display:block;
width:auto;
margin:0;
padding:0;
color:#707070;
text-decoration:none;
}

One solution is to compare previous text with new:
$('.shop').click(function() {
$('.shopList').slideToggle("fast");
$("a span", this).text() == "+" ? $("a span", this).text("-") : $("a span", this).text("+");
});
nav {
position: relative;
display: block;
width: 70%;
margin: 0;
padding: 3px 15%;
border-top: 1px solid #d0d0d0;
text-align: center;
font: 15px'OpenSans';
z-index: 999;
}
nav ul {
position: relative;
width: 100%;
margin: 0;
padding: 0;
}
nav li {
display: inline-block;
margin: 0 10px;
padding: 0;
}
nav li ul {
display: none;
}
nav li ul li {
position: relative;
display: block;
width: 150px;
margin: 0;
padding: 0;
}
.shopList {
position: absolute;
display: none;
width: 100px;
margin: 0 0 0 -50px;
padding: 0;
}
nav a {
position: relative;
display: block;
width: auto;
margin: 0;
padding: 0;
color: #707070;
text-decoration: none;
}
