jquery slidetoggle() not hiding :before element

All of my elements hide and show correctly using slidetoggle(), EXCEPT for my li:before. I've tried forcing the overflow, visibility, display, etc on the :before and the li, and nothing is helping, it still shows the bullets set using the :before class. What needs to happen to hide these bullets when slidetoggle() is activated/deactivated?
jQuery(document).ready(function($) {
$("#read-more").click(function(){
$(".careers-position").slideToggle(800);
return false;
});
});
ul {
line-height: 2.4em !important;
margin-left: 20px;
padding: 0 0 23px 1em;
}
li {
list-style: none !important;
color: #656565;
}
li:before {
content: "";
background: #9e9e9e;
width: 6px;
height: 6px;
display: block;
position: absolute;
left: 18px;
margin-top: 16px;
border-radius: 20px;
overflow: hidden;
backface-visibility: hidden;
}
.careers-position {
display: none;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="careers-position">
<h3>Pilot</h3>

Demo

Here look at this fiddle https://jsfiddle.net/wfccp58p/4/
ul { line-height: 2.4em; margin-left: 20px;padding: 0 0 23px 1em;list-style-type: none;}
I removed the li:before and added the list-style-type to the ui. Not sure if you still wanted some of the LI:Before pseudo stuff, but this fixes your issue.

Responsive nav not appearing as intended

I am trying to create a responsive nav bar, but I am coming across issues making it appear in the way intended.
Here is an image of how it looks when window is maximized:
Here is an image when the window is resized:
Here is an image of what I want the page to look and function like:
Issues:
As the images show, the header currently shows the links "stretches, mobility" etc, when I want it to display "Join / Log In" etc (image 3).
When menuis clicked, I want the nav to dynamically display the other links.
Here is what I have tried so far: https://jsfiddle.net/hudnybux/

Ok, I think I got it to look almost exactly like your screenshots. One of the main things I had to do was move your nav-trigger up within html.
<div id="header-main">
<div id="nav-trigger"><span>Menu</span></div>
<nav id="main-navigation" role="navigation">
<ul>
<li>Stretches</li>
<li>Mobility</li>
<li>Posture</li>
</ul>
</nav>
<!--<nav id="nav-mobile"></nav>-->
</div>
Technically you no longer need nav-mobile nav. I also fixed your caret triangle next to "menu". It needed a height and width of 0.
width: 0;
height: 0;
Edit:
I have revisited my solution. Just as a suggestion, I am recommending css transitions instead of jQuery slideDown and slideUp. You were already applying a class and that is all we need to create dynamic animations. jQuery's methods apply the styles inline and frankly leave you with less flexibility.
https://jsfiddle.net/qnco3x7e/8/

You will need to add another media query
#media all and (max-width: 460px) {
nav#main-navigation li {
display:block;
border-bottom: 1px solid #fafafa;
}
}

You can use flexbox css properties. It's very powerfull. http://www.alsacreations.com/tuto/lire/1493-css3-flexbox-layout-module.html

Writing others' code for them is not in the spirit of Stack Overflow, but, as I prefer teaching by showing and not telling, I went ahead and did the task for you. Observe how I changed your implementation and learn as much as you can!
The Strategy
Use the same HTML markup for the main menu (Stretches, Mobility, Posture) on both large and small screen widths, instead of using JavaScript to duplicate it in two places.
Use the same CSS for both menus as a starting point; in the media query for small screen sizes, change the main menu to be horizontal
Show everything by default; use display: none only on screen sizes you don't want to show something on.
JSFiddle
$(document).ready(function() {
$("#main-nav-mobile-trigger span").click(function() {
$(this).toggleClass("open");
if ($(this).hasClass("open")) {
$("#main-nav").addClass("open").slideDown(250);
} else {
$("#main-nav").removeClass("open").slideUp(250);
}
});

The HTML
I removed your container <div>s (#header and #header-main), as they serve no purpose as far as layout is concerned.
There are now only three parts to the header area. In order they are:
#top-nav - Join/Login, Help, Shop
#main-nav-mobile-trigger - MENU button
#main-nav - Stretches, Mobility, Posture
The JavaScript
When the MENU button (#main-nav-mobile-trigger span) is clicked:
Toggle its .open class.
If it has the .open class,
Add #main-nav's .open class.
Otherwise,
Remove #main-nav's .open class.
The CSS
You had duplicates of the styling rules for each horizontal menu (formerly #nav-main and #main-navigation, which are very easy to confuse). These are now combined into one set of rules under the more general selector, nav. Additionally, their text-align is set to center by default (the desired alignment on small screen widths).
For big screen widths (#media all and (min-width: 901px)):
Align #top-nav to the right and #main-nav to the left.
Hide the MENU button.
For small screen widths (#media all and (max-width: 900px)):
If #main-nav doesn't have the .open class, hide it.
Display the menu items in #main-nav horizontally.
I hope this helps you. Best of luck with your future adventures in front-end development!

Appearing <div> should push images below down

I've got an HTML-File.
As you can see, if you click on an image it opens a box below with some text. That works with jQuery. Is there a way to push the images under the box down?
So that the box never covers an image. Please note that it should be responsive.
Here's the fiddle:
That's the css:
#projekte {
list-style: none;
text-align: center;
width: 100%;
}
#projekte li {
display: inline-block;
margin: 10px 5px 10px 5px;
width: 300px;
}
#projekte img {cursor: pointer; width: 300px;}
.beschreibung {
background-color: #bec3c8;
display: none;
width: 100%;
left: 0;
position: absolute;
}

don't make the .beschreibung elements absolutely positioned, as this will take them out of the flow of the document. Change your css to:
.beschreibung {
background-color: #bec3c8;
display: none;
width: 100%;
}
Updated fiddle (with vertical-align:top as stated in comments)

You have to change position parameter to relative
.beschreibung {
background-color: #bec3c8;
display: none;
left: 0;
position: relative;
}
And using jQuery, you can set it's width, like:
jQuery(".beschreibung").width("desired width");
EXAMPLE FIDDLE
Also, you need to hide previous image description, like:-
$("div[id^='projekt']").hide();

You can change your CSS Class position: relative
.beschreibung {
background-color: #bec3c8;
display: none;
width: 100%;
left: 0;
position: relative;
}

So I just found an easy solution. I just put the .beschreibung in a wrap div and set the .beschreibung to 100% width. You can find the updatet fiddle here: https://jsfiddle.net/znt3npqa/9/

How would I add text before the numbers in odometer.js

I am using the odometer.js library and I want to add a '$' right before the display of numbers. (EX: $123,435) Does anyone know how to go about this to get it to work? I have tried adding tags and inserting it in the options section of the javascrip which is in correlation with the library, but it still will not work. I have also tried :before and :after pseudos but that is not very dynamic.
<div class="odometer" id="odometer"></div>
.odometer {
color: rgba(250,250,250,.75);
font-size: 50px;
margin-top: 100px;
background-color: #2ecc71;
text-align: center;
padding-top: 10px;
position:fixed; top: -50px; width:100%; border: 0px solid black !important;
}
.odometer:before {
content: "$";
}

This should do the trick:
.odometer-inside:before {
content: "$";
}

CSS - displaying a dynamic height floated DIV - missing background image

My Goal:
Here is what I'm trying to accomplish. We have an list of categories that appear on a page. The number of categories is unknown. The description can be pretty much any size... yet we want a uniform look. So, we are using the dotdotdot plugin to put ellipses on the paragraphs. When you hover over the item, it should expand the description and show the full text.
I want that hover to float or overlay whatever is below it. Due to some of my layout items (see my NOTE below) my sccontainer element doesn't have a set height. It's dynamic based on the content... with a max-height set.
When I change that height to AUTO in the hover event (which causes the text to flow down and displays all the content), I lose the background on the sccontainer element.
Some pertinent CSS:
.sccontainer { width: 280px; zoom: 1; float: left; margin: 5px 10px; padding: 0; border: 1px solid #8697a1; -moz-border-radius: 5px; border-radius: 5px; -moz-box-shadow: 0 0 6px #777; -webkit-box-shadow: 0 0 6px #777; box-shadow: 0 0 6px #777; -ms-filter: "progid:DXImageTransform.Microsoft.Shadow(Strength=6, Direction=90, Color='#777777')"; filter: progid:DXImageTransform.Microsoft.Shadow(Strength=6, Direction=90, Color='#777777'); position: relative; background: #fff url(http://imagecss.com/images/background.jpg) repeat-x left top; }
.sccontainer .parent { position: absolute; width: 270px; }
.sccontainer .image { margin: 5px; float: left; }
.sccontainer .image img { width: 48px; }
.sccontainer .icon { margin: 0; }
.sccontainer p { margin: 8px; padding: 0; max-height: 145px; }
.sccontainer h1 { line-height: 24px; display: inline-block; vertical-align: middle; width: 200px; height: 48px; padding: 0; margin: 5px 0 0 0; overflow: hidden; }
.sccontainer h1 a { padding: 0; font-size: 24px; color: #fff; font-weight: normal; }
.sccontainer .content { position: relative; height: 210px; padding: 0 5px; font-size: 15px; line-height: 22px; width: 270px; }
.sccontainer a:hover { text-decoration: underline; }
.sccontainer.hover { height: 250px; }
.sccontainer.hover .content { height: auto; }
.sccontainer.hover .content p { min-height: 135px; max-height: none; }
jsFiddle:
Here is a jsFiddle version of what I have right now. You can see this in action, if you hover over the text in the blue box. It's a bit large, so I used jsFiddle instead of putting all the bits here code tags...
http://jsfiddle.net/ztMM5/1/
And here is a mockup of what I'd like to see. Method 5a expands slightly to show the full content.... yets overlaps the red line. None of the other items move around or are affected.
NOTE: Sorry for the size of things. I've trimmed it down about as much as I can. Also, I am modifying an existing intranet website... it's 3rd party, so I have limited control of the source code - hence the table usage. :(
What I've Tried/Researched:
I believe the issue stems from the fact that my sccontainer item is floating, and doesn't have a height specified. That's why the image disappears.
I had a version that kept the background... but the sccontainer box didn't resize like we need... the text just overflowed it... rather ugly.
I don't know enough CSS to make this all work right. I'm not adverse to using jQuery to do more if needed.
I did work on a version that handled most of the hover using the :hover stuff... but it didn't work quite as well as the jQuery approach.

This answer may not solve your specific problem but it may help others with a similar scenario (working with tables makes difficult to render a clean layout in most cases.)
I ran into this issue before and this is how I solved it. It basically relies in an html nested div structure to achieve the expandability of the content without affecting the floating layout of the near elements :
<div id="wrapper" class="cf"><!--wrapper with border and CLEARED-->
<div class="sccontainer"><!--position relative-->
<div class="inner"><!--position absolute-->
<div class="content"><!--position relative-->
<!-- my content here -->
</div>
</div>
</div>
<!-- more containers etc-->
</div><!--END wrapper-->
First, we are going to apply the infamous clear-fix hack to the #wrapper container (use your preferred method):
.cf:after {
visibility:hidden;
display:block;
content:"";
clear:both;
height:0
}
* html .cf {
zoom:1
}
/* IE6 */
*:first-child+html .cf {
zoom:1
}
Then the style for the .sccontainer container :
.sccontainer {
width: 280px; /* or whatever - could be % for responsiveness */
padding-bottom:200px; /* any value to give height without using height ;) */
position: relative;
float: left;
margin: 5px 10px; /* or whatever */
overflow: hidden; /* this is important to keep all same height and big content out of sight */
z-index: 1; /* this is important too, see later */
background: white url("imagebackground.jpg") 0 0 repeat-x; /* need to explain? */
}
Then the .inner container, which actually will help to keep the layout in order if we hover the elements
.inner {
position: absolute; /* please don't move */
width: 100%; /* to fill the whole parent container */
height: 100%; /* same */
}
And the content :
.content {
position: relative;
background: white url("imagebackground.jpg") 0 0 repeat-x; /* not redundant though */
width: 100%; /* helps to fill the gaps with small content */
height: 100%; /* same, specially if using image backgrounds */
/* other styles, etc */
}
NOTE: we should apply same border-radius properties to the three containers and box-shadow to .sccontainer and .content for consistency
Now, what happens when we hover ?
.sccontainer:hover {
overflow: visible; /* show the full content */
z-index: 999; /* place me on top of the others if needed (which lower z-index, remember?) */
}
.sccontainer:hover .content {
height: auto; /* as it really is, including background image */
}
NOTES : this effect will happen regardless if the content's height is smaller than the parent container's height. You may not like the effect mostly if you are using borders and shadows (could be shown as smaller box inside the parent container) so we could add an extra class to .sccontainer like
<div class="sccontainer withhover">
and apply the hover effects only if that class exist like
.sccontainer.withhover:hover {
overflow: visible;
z-index: 999;
}
... and use a bit of jQuery to remove that class for shorter content, so it won't be affected :
jQuery(document).ready(function ($) {
$(".sccontainer").hover(function () {
var $contentHeight = $(this).find(".content").height();
if ($(this).innerHeight() > $contentHeight) {
$(this).removeClass("withhover");
}
});
});
