Hamburger menu doesnt show in responsive navbar - css

Question

Hello I'm really new in this web programming, just learned a few days ago, and try to make responsive navbar of mine. And I found tutorial on w3school, I followed it, and change some code, but it didnt work as intended. The menu succeed to collapse on desired width, but the hamburger menu doesnt show up. I think I already change and match it with my classes, but I dont know what else is wrong.
Here is what I have tried so far:
.navSection {
width: 100%;
display: inline-table;
line-height: 30px;
background: #1c948a;
z-index: 3;
box-shadow: 0px 3px 5px 1px rgba(0, 0, 0, .3);
}
.navMenu .icon{
display: none;
}
#media screen and (max-width: 700px) {
.navMenu ul li:not(:first-child) {display: none;}
.navMenu ul li.icon {
float: right;
display: block;
}
}
#media screen and (max-width: 700px) {
.navMenu.responsive {position: relative;}
.navMenu.responsive .icon {
position: absolute;
right: 0;
top: 0;
}
.navMenu.responsive ul li {
float: none;
display: block;
text-align: left;
}
}
.navSectionWrapper {
width: 90%;
margin: auto;
}
.homelink {
text-decoration: none;
}
.navlogo {
width: 30%;
height: 70px;
float: left;
}
.logo {
display: inline-block;
font-family: "Trebuchet MS", "Lucida Grande", "Lucida Sans Unicode", "Lucida Sans", Tahoma, sans-serif;
color: #2C3E50;
position: absolute;
}
.logoimg {
height: 70px;
float: left;
}
.logotext {
font-weight: 600;
float: right;
line-height: 70px;
}
.logotext>span {
color: white;
text-shadow: 2px 2px 2px #33425B;
}
.navMenu {
float: right;
text-align: center;
overflow: hidden;
}
.navMenu>ul {
list-style: none;
}
.navMenu>ul>li {
display: inline-block;
line-height: 70px;
}
.navMenu>ul>li>a>span {
color: white;
font-weight: 700;
font-size: 17px
}
.navMenu>ul>li>a {
text-decoration: none;
color: #2C3E50;
font-family: "Trebuchet MS", "Lucida Grande", "Lucida Sans Unicode", "Lucida Sans", Tahoma, sans-serif;
font-weight: 600;
margin: 10px
}
.navMenu>ul>li>a:hover {
color: snow;
}
<div class="navSection">
<div class="navSectionWrapper">
<div class="navlogo">
<a href="#" class="homelink">
<div class="logo">
<img src="img/logo.png" class="logoimg">

<div class="navMenu" id="mynavMenu">

<li>Home</li>
<li>Features</li>
<li>About</li>
<li>+<span>Download</span></li>
<li>☰</li>
</ul>
</div>
</div>
</div>
<script>
function myFunction() {
var x = document.getElementById("mynavMenu");
if (x.className === "navMenu") {
x.className += " responsive";
} else {
x.className = "navMenu";
}
}
</script>

Your HTML uses a.icon but you're targeting in CSS with li.icon. Moved the class="icon" to the li instead of the a and modified the CSS for .icon a bit. You were hiding :not(:first-child()) in the responsive view, and you either want to use :not(:last-child) since .icon is the :last-child or just use :not(.icon) there instead.
.navSection {
width: 100%;
display: inline-table;
line-height: 30px;
background: #1c948a;
z-index: 3;
box-shadow: 0px 3px 5px 1px rgba(0, 0, 0, .3);
}
.navMenu .icon{
display: none;
float: right;
}
#media screen and (max-width: 700px) {
.navMenu ul li:not(.icon) {display: none;}
.navMenu ul li.icon {
display: block;
}
}
#media screen and (max-width: 700px) {
.navMenu.responsive {position: relative;}
.navMenu.responsive .icon {
position: absolute;

top: 0;
