How can I make my modal background go to the bottom of the page rather than the bottom of the viewport?

I need to make a lightbox for pictures on this portfolio website. I have everything hooked up so the image goes to the original size when being clicked on, like a simple lightbox. But the problem I'm having is that the background behind the modal only goes down to the bottom of the viewport instead of going all the way to the bottom of the page. Let me know if theres any additional information I can provide.
Lightbox Problem
#overlay {
background: rgba(0,0,0,0.8);
width: 100%;
height: 100%;
position: absolute;
top: 0;
left: 0;
display: none;
text-align: center;
}
#overlay img {
border-radius: 4px solid white;
margin-top: 10%;
}
#overlay p {
color: white;
}

Change position to fixed like this:
#overlay {
background: rgba(0,0,0,0.8);
width: 100%;
height: 100%;
position: fixed;
top: 0;
left: 0;
display: none;
text-align: center;
}

How to make an image the full width of a screen with dictating the height

I created an image slider, but I am running into an issue. I want the width of the images to be the entire width of the screen; I accomplished this. However, my images' height are more than 100% of the height of the screen. I am wanting the height to be around 50-70% of the screen (preferably 50%). I tried adding height: 70vh; to my images, but that did not help.
Can anyone suggest something to help this?
My slider can be viewed at: http://realtorcatch.com/slider3
My code is:
* {
padding: 0;
margin: 0;
}
body {
font-family: Sans-Serif;
}
img {
max-width: 100%;
/*height: 70vh;*/
}
.cycle-slideshow {
width: 100%;
display: block;
position: relative;
margin: 0 auto;
}
.cycle-prev, .cycle-next {
font-size: 200%;
color: #FFF;
display: block;
position: absolute;
top: 50%;
margin-top: -10px;
z-index: 999;
cursor: pointer;
}
.cycle-prev {
left: 10%;
}
.cycle-next {
right: 10%;
}
.cycle-pager {
width: 100%;
text-align: center;
display: block;
position: absolute;
bottom: 20px;
z-index: 999;
cursor: pointer;
}
.cycle-pager span {
text-indent: 100%;
white-space: nowrap;
width: 12px;
height: 12px;
display: inline-block;
border: 1px solid #FFF;
border-radius: 50%;
margin: 0 10px;
overflow: hidden;
}
.cycle-pager .cycle-pager-active {
background-color: #FFF;
}
<div class="cycle-slideshow">
<span class="cycle-prev">〈</span>
<span class="cycle-next">〉</span>
<span class="cycle-pager"></span>
<img src="images/subway.jpg" alt="subway">
<img src="images/beach.jpg" alt="beach">
<img src="images/space.jpg" alt="space">
</div>

On your img declaration, instead of max-width set width to 100% and height to 70vh. If you'd like more variety in the height, try setting the min-height to be 50vh and the max-height to be 70vh.
Be warned, this will skew your images and make them look disproportionate.
Alternate solution:
Create a "scrim". By this, I mean create a box that covers up the bottom half of the page. You can actually do this with a pseudo-element from your wrapper:
.cycle-slideshow {
position: relative;
...
}
.cycle-slideshow:after {
content: '';
width: 100%;
height: 50%; //50% of parent element
background-color: white;
position: absolute;
top: 50%;
left: 0;
z-index: 2;
}

change style of img to img {width: 100%; height: 100vh;}
It will work for you. Thank you.

try this,, Hope it will help you.
var vHeight = $(window).height()/2, // for 50%
vWidth = $(window).width(),

Margin-left doesn't work properly in Firefox

In my code margin-left: is working in two different ways in Firefox and all the other browsers.
On Firefox, the margin is only like 20% of the "real" margin. I tried #-moz-document url-prefix() { }, but it didn't solve the issue, it moved both the image that is shown and the "real position from where the cars start moving" to a even bigger margin.
Here's my code:
<section id="home" >
<div id="home1inner">
<div id="header">
*lots of content here*
</div>
<img id="cars" src="images/cars.png" />
</div>
</section>
#home {
position: relative;
width: calc(100% + 25px);
overflow-y: scroll;
background-image: url('images/movie_6.jpg');
background-repeat: no-repeat;
background-position: center;
height: 690px;
margin-top: 40px;
}
#home1inner {
height: 1550px;
overflow: hidden;
position: relative;
}
#cars {
position: absolute;
height: 690px;
bottom: -500px;
margin-left: -300px;
pointer-events: none;
}
Here's the website itself, where you can check the difference between Firefox and any other browser: http://denea.comeze.com/
Any ideas how to fix it?

In Firefox, your cars ID is defaulting to be centered on the page.
Simply add left: 0, like so:
#cars {
position: absolute;
height: 690px;
bottom: -500px;
margin-left: -300px;
pointer-events: none;
left: 0;
}
and it will start off at the position on the page you want.

Smart Sticky Navigation Menu

I'm having a small problem with some text jumping around in my sticky menu. This is my code: http://jsfiddle.net/u6ywraj8/
As you can see, I want the red #menu to stick to the top when a user scrolls down. However, the text in the top left part of the menu jumps around. I want this text to always be in the top left part of the red menu, I don't want it to have the initial ~100px padding.
Thank you for your help!

Try this one
sticknav {
background: none repeat scroll 0 0 #ffffff;
display: inline-block;
height: 30px;
left: 0;
margin-left: 0;
margin-right: 0;
position: relative;
right: 0;
width: 100%;
z-index: 9999;
}

Add float: left; to this class sticknav{}
sticknav {
background: #ffffff;
height: 30px;
width: 100%;
margin-right: 0px;
margin-left: 0px;
left: 0px;
right: 0px;
position: relative;
z-index: 9999;
float: left;
}

Horizontally and vertically align image in div

I'm using Bootstrap and WordPress.
I've been researching how to horizontally and vertically align an image inside a div (classic problem, apparently). I used the answer to this question to vertically align my image: How to vertically align an image inside div
Now I need to horizontally align it. I know to do that, you normally add margin: 0 auto;
The problem is that the method that I followed uses margin:auto; and it undos the vertical align if I change it to margin:0 auto;
I started to make a JSFiddle of the problem, but I couldn't replicate it. So I think it's something in Bootstrap that is overriding it, but I'm not sure what.
Here is the basic code I'm using from the vertical align solution on the other stackoverflow question:
HTML
<div class="crop-featured-2">
<img src="image.png">
</div>
CSS
.container {
position: relative;
width: 100%;
overflow: hidden;
}
.crop-featured-2 {
height: 100px;
width: 200px;
position: relative;
border: 1px solid red;
padding: 5px;
display:block;
}
.crop-featured-2 img {
min-height: 100px;
width:100%;
position: absolute;
top: 0;
bottom: 0;
left: 0;
right: 0;
margin: auto;
border:0px;
padding:0;
}
You can see the problem at http://ucaftercruz.com/upcoming/?page_id=30. It's the slider at the top and the problem is in the .carousel-inner div. Resize the browser to around 800px wide to be able to really see the issue.
Thanks so much in advance!

I had a look at your web page. I think the issue solves it self if you just remove the width rule from this selector:
.crop-featured-2 {
height: 320px;
width: 575px;
position: relative;
}
instead use
.crop-featured-2 {
height: 320px;
position: relative;
}

Try this
.crop-featured-2 {
position: relative;
margin: 0;
position: absolute;
top: 50%;
left: 50%;
margin-right: -50%;
transform: translate(-50%, -50%);
}
