The code for my navbar does not work properly

I'm a beginner trying to code a navbar in a practice website but I can't get the final product right.
My navbar is supposed to line up horizontally along the top of the page and then be follow the page as you scroll with a black shadow backdrop. Currently when you load the page, the words line up vertically on the right side, and then condense when you scroll. I also have a logo in the top left that shrinks way too small. Finally, when when you shrink the page, a hamburger icon pops up in the top right that is supposed to show you the menu options, however it no longer works. It's like a cycle with this page, I fix one thing and break another. I am doing this just for fun because I'm trying to learn but now I'm getting frustrated, Thanks!

HTML/CSS Jquery hover not showing up

I am new to Jquery and
I am trying to make a dropdown on my navigation using simple Jquery hover effect, and I think I am using wrong selector on Jquery.
I would like to see the dropdown and be able to navigate when i hover over 'What's New'
Any help would be awesome. Thanks,

You should use a nested ul for your dropdown menu. You don't need jQuery at all for this. It can all be done with CSS. Take a look at this simple hover effect under the Products tab.

Your submenu is hidden with visibility: hidden style.
I also separated the handled so that the menu doesn't hide while you're hovering it, and added finish() so that we're not queueing animations.
But yeah, like ncox85 said you should do this with css.
$(document).ready(function () {
$('.nav-level-2').hide();
$("li .nav-level-1").mouseenter(
function () {
$('.nav-level-2').finish().slideDown('200');
}
);
$("li .nav-level-2").mouseleave(
function () {
$('.nav-level-2').finish().slideUp('200');
});
});

Just use display:none instead of visibility:hidden on class .nav-level-2

If any of you are wondering, I got a good result from just using html/css, got rid of jquery.
Maybe I will use jquery another time. fun lesson for myself and those of you out there. Thanks guys

Change menu button to graphic on click

Currently I have a hamburger menu button: https://jsfiddle.net/sqvwm1dh/
When this button is clicked, I'd like to replace this button with a graphic.
How do I achieve this with my current code. Do I do this in jQuery?
$('header').prepend('<div id="menu-button"></div>');
$('#menu-button').on('click', function(){
var menuItems = $(".menu-primary-menu-container");
menuItems.toggle();
});
header {
background:red;
height:100px;
}
#menu-button {
position: relative;
z-index: 10000;
display: block;
top: 30px;
right:0;
position: fixed;
-webkit-box-sizing: border-box;
-moz-box-sizing: border-box;
box-sizing: border-box;
width: 100%;
padding: 15px 0px 22px 20px;
text-transform: uppercase;
font-weight: 700;
font-size: 14px;
letter-spacing: 1px;
color: #ffffff;
cursor: pointer;
}
/* line 500, sass/_layout.scss */
#menu-button:after {
display: block;
content: '';
position: absolute;
height: 3px;
width: 22px;
border-top: 2px solid #ffffff;
border-bottom: 2px solid #ffffff;
right: 20px;
top: 16px;
}
/* line 511, sass/_layout.scss */
#menu-button:before {
display: block;
content: '';
position: absolute;
height: 3px;
width: 22px;
border-top: 2px solid #ffffff;
right: 20px;
top: 26px;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script>
<header>
<div class="menu-primary-menu-container">
test
</div>
</header>

$(this).toggleClass('active');
Then in your CSS add a style for your #menu-button with the .active class and set for instance a background image. Or do something else.

You need to put quotes around 'swing' in the animation style.
$(".icon-open").click(function(){
$("nav").animate({left: "-16em"}, 500, 'swing');
});
http://codepen.io/anon/pen/BNGWrE
Edit
Added a variable called navhidden so you can toggle the showing and hiding of the nav:
Refresh / open above CodePen link.
$(".icon-open").click(function() {
if (navhidden) {
//Show
$("nav").animate({
left: "0"
}, 500, 'swing');
navhidden = false;
} else {
$("nav").animate({
left: "-16em"
}, 500, 'swing');
navhidden = true;
}
});

In this JSFiddle you can find it works when clicking the image.
$(document).ready(function(){
$(".scroll-menu").click(function(){
$(".scroll-menu").hide();
});
$(".box").click(function(){
$(".box").hide();
});
$(".icon-open").click(function(){
console.log('Image clicked');
$("nav").animate({left: "-16em"}, 500, 'swing');
});
});

How do i do this with hover effect with javascript/jquery?

So i am slightly new to JS and jQuery, but i know html and css very well. I want to know if this is possible to do.
I have some HTML code for a nav in an info area. I have it all set up and I have it so it calls a function on mouseover, this function turns the color of the link to white. And for mouseout it turns it black again. Now I know you can probably do this with css but I need the practice for Js/jQuery. I wrote some code and it works and all but instead it colors all the colors white and it blends in, test the code and you will see. Is there a way to only choose the selected button and color only that one. maybe with an array or something?? I dont really need to know if there is a way to do it with css, i just need to get into the habit of using js/jQuery.
Code:
function colorLink() {
$(".infoNav nav ul li a").css("color", "white");
}
function colorLinkOut() {
$(".infoNav nav ul li a").css("color", "black");
}

Yes there is a way, but if you are using jQuery you'd be better hooking to the events in a jQuery way, so remove those onmouseover="colorLink()" and onmouseout="colorLinkOut()" from the html and replace your javascript for
$(function(){
$(".infoNav li").mouseover(function(){
$(this).find("a").css("color", "white");
});
$(".infoNav li").mouseout(function(){
$(this).find("a").css("color", "black");
});
});
by hooking through jQuery instead of plain javascript you can now use the "this" keyword as a reference to the element that generated the event, that's why $(this) works here, but would not work your previous code.
