picture/video link opening on top of page

I'm VERY new to html coding (5/6 weeks) and I'm having a problem getting my head around something. I'd like to be able to click on an image and instead of opening a new page have it's image or embedded video load inside a floating page (I'm sure there is a correct name for this) that loads on top of the existing page.
I've found several examples of this (one of which is linked below) but I'm still baffled. Is it just code from the main.css I need or do I require javascript etc. aswell. I've tried copYing over several bits of css code but to no success. It seems to always open a new page and not a floating page like in the example I've included below.
example: https://html5up.net/parallelism
when you click an image in the above site it opens/pops up a floating box (again sorry for not knowing what it is called) in the way I'd love to understand. I really want to use this technique as my site will be image and video heavy. I feel this approach will be a far a more professional way to display my information and images.
If anyone can help I'd love to learn exactly what I need to do to implement this. It might only be 5/6 weeks but I feel I've learned quite a bit. I want to keep upskilling to the point that I can maintain this website entirely by myself.
Thanks to everyone in advance,
Al.

Invert colors of html when clicking (except imgs)

I've created an on/off button and I would like for the html's content's colors to invert when on and to be normal when off! And also I would like for the images and gifs to stay the same color.. I know it's complicated :x But the problem is since the button would be inside a div in html I can't use + space ~ or > to trigger the effect.. Does anyone know how it would be possible to do it please?
Here's the code for now but it's wrong for the html part..
function invertFunction(x) {
x.classList.toggle("invertbutton");
}
.invertfunction{
cursor:pointer;
position:fixed;
top:20px;
left:20px;
width:60px;
height:30px;
}
#onbutton{
width:60px;
height:30px;
background-color:#fff;
border-radius:10px;
border:1px solid #848484;
-webkit-transition:.3s ease;
-moz-transition:.3s ease;
-o-transition:.3s ease;
transition:.3s ease;
}
#movingbutton{
width:30px;
height:30px;
border-radius:10px;
border:1px solid #848484;
background-color:#BDBDBD;
-webkit-transition:.2s ease;
-moz-transition:.2s ease;
-o-transition:.2s ease;
transition:.2s ease;
}
.invertbutton #onbutton{
background-color:#42B94E;
}
.invertbutton #movingbutton{
transform: translate(30px);
}
.invertbutton .html{
-webkit-filter: invert(100%);
filter: invert(100%);
}
<html>
<div class="invertfunction"onclick="invertFunction(this)">
<div id="onbutton">
<div id="movingbutton"></div>
</div>
</div>
</html>
Thanks for the help! :)

You can use this code here:
function invertFunction(x) {
x.classList.toggle("invertbutton");
if ($("div:not(#movingbutton)").css('filter') == 'invert(0%)') {
$("div:not(#movingbutton)").css('filter', 'invert(100%)');
$("img").css('filter', 'invert(100%)');
} else {
$("div:not(#movingbutton)").css('filter', 'invert(0%)');
$("img").css('filter', 'invert(0%)');
}
}
And you can remove this css:
.invertbutton .html{
-webkit-filter: invert(100%);
filter: invert(100%);
}
function invertFunction(x) {
x.classList.toggle("invertbutton");
if ($("div:not(#movingbutton)").css('filter') == 'invert(0%)') {
$("div:not(#movingbutton)").css('filter', 'invert(100%)');
$("img").css('filter', 'invert(100%)');
} else {
$("div:not(#movingbutton)").css('filter', 'invert(0%)');
$("img").css('filter', 'invert(0%)');
}
}
div:not(#movingbutton) {
filter: invert(0%);
}
.invertfunction {
cursor: pointer;
position: fixed;
top: 20px;
left: 20px;
width: 60px;
height: 30px;
}
#onbutton {
width: 60px;

border: 1px solid #848484;

Show div when hover over another separate div

I have searched the web and found similar questions to my own, but I have not been able to achieve the results that I am looking for. I am not the most well versed with html/css/and javascript/jquery so I am wondering if it is an error on my part with how I am formatting everything, or the path to which I am trying to write these results.
I have three circles, spaced equally in the center of the page. Each circle links out to a different page. On hovering over a circle, a span is revealed (by changing the opacity property in css) that provides a title for where that link goes.
What I am having trouble doing is: When you hover over each circle, in addition to a span being revealed that provides a title, I want to have a short descriptive text appear below the circles. When you mouse out of that said circle, the descriptive text will disappear. Each circle must have its own descriptor text.
From what I have gathered, the jquery hover on event is likely the best way to do this, however I cannot seem to get the syntax correct to make it work.
<script>
jQuery(document).ready(function() {
jQuery('#text1').hide();
});
jQuery(document).ready(function() {
jQuery('.grid_1').hover(function() {
jQuery(this).find('#text1').show();
},
function() {
jQuery('#text1').hide();
});
});
</script>
Any and all help would be greatly appreciated. Please let me know if I should clarify anything.
Link to jsfiddle

Your jquery references #text1 and it should be .text1 since that element is a class. Also $(this).find('.text').show(); won't work because .text is not a child of the thing you're hovering over ($(this)). Just use $('.text1')
$(document).ready(function() {
$('.text1').hide();
});
$(document).ready(function() {
$('.grid_1').hover(function() {
$('.text1').show();
},
function() {
$('.text1').hide();
});
});

Though I would re-write it to be a little more flexible and with less code like this, utilizing a data attribute in the .grid circles to define the text block class to show, then adding/removing a class that shows the text instead of using jquery's $.hide() and $.show()
$(document).ready(function() {
$('.grid').hover(function() {
$($(this).attr('data-text')).addClass('show');
},
function() {
$($(this).attr('data-text')).removeClass('show');
});
});

I'll provide a css solution since there exist a jquery answer
Add the following to your css
.fmcircle_out:hover .description{
opacity:1;
}
.description{
opacity:0;
transition:opacity 1s;
}
.fmcircle_out a{
text-decoration:none;
}
.fmcircle_out:focus {
opacity: 1;
}

Jquery code Which hide another div on hover and make it visible when mouse move out.
<script>
$(document).ready(function(){
$('.grid_1').hover(
function () {
$('#text1').hide();

function () {
$('#text1').show();
}
);

Using media queries on content loaded by AJAX

Is there any possible way to use media queries on content loaded by AJAX? I'm using .load() to load a html snippet into the web page. It is a light box I created using CSS. The problem is that media queries don't seem to have any effect on it.
Once the movie has been clicked, a html snippet is loaded into the div "lightbox-target" and a lightbox appears up on the screen. The lightbox is styled using ".detail".
<div class="template actionmovies">
<h1 class="name">Batman: The Dark Knight</h1>
<h2 class="imdb">9/10</h2>
<h3 class="rotten">94%</h3>
<a class="lightbox" href="#The_Dark_Knight" name="The_Dark_Knight">
<img src="images/darkknight.jpg" />
</a>
</div>
<!-- the HTML snippets load inside this div -->
<div class="lightbox-target">
</div>
CSS
.lightbox-target {
position: fixed;

width: 100%;

How do I make content derived from css clickable?

What should I do such that when i mouse over the '+' , the add to my playlist appear and i'm ABLE to click on the "add to my playlist" and make it linkable. Right now, everytime i try to hover onto add to my playlist, it disappears. :(
(http://i62.tinypic.com/16bhbit.jpg)
Current jfiddle: http://jsfiddle.net/gmraK/
The add to my playlist is generated by
.addtoplaylist-video:hover:after{
background-color: #ffffff;
background:rgba(30,120,160,0.8);
border-color: rgba(30,120,160,0.8);
border-right-color: #ffffff;
border-radius: 5px;
top: -32px;
color: #ffffff;
content: 'Add To My Playlist!';
left: -100px;
padding: 5px 5px;
position: absolute;
z-index: 98;
width: 120px;
height:15px;
text-align:center;
-webkit-transition: all 0.3s ease-in-out;
-moz-transition: all 0.3s ease-in-out;
-o-transition: all 0.3s ease-in-out;
-ms-transition: all 0.3s ease-in-out;
transition: all 0.3s ease-in-out;
filter: progid:DXImageTransform.Microsoft.gradient(GradientType=0,startColorstr='#1e78a0', endColorstr='#1e78a0');
box-shadow: 1px 1px 2px rgba(0,0,0,0.1);
cursor:pointer;
}
html
<div id="video1" class="toggle">
<span class="addtoplaylist-video">
<img src="images/addicon.png" width="12" height="11" alt="add" class="addplaylisticonimg"></span>
<span class="viewplaylist-video">
<img src="images/viewicon.png" width="17" height="9" alt="viewicon" class="viewplaylisticonimg"> </span>
</div>
js
<script type="text/javascript">
$('.addtoplaylist-video').on('click', function(){
$(this).css({'display':'none'});
$(this).parent('.toggle,.toggle2')
.find('.viewplaylist-video')
.css({'display':'block'});
});
$('.viewplaylist-video').on('click', function(){
$(this).css({'display':'none'});
$(this).parent('.toggle, .toggle2')
.find('.addtoplaylist-video')
.css({'display':'block'});
});
</script>

Try this: http://jsfiddle.net/gmraK/2/
I removed the dynamic css div/link and add a div that is only displayed when the parent has the class of active. A class which is added on hover of the toggle element.
So to begin, I removed your :hover:after
.addtoplaylist-video:hover:after {
background-color: #ffffff;
background:rgba(30, 120, 160, 0.8);
border-color: rgba(30, 120, 160, 0.8);
border-right-color: #ffffff;
border-radius: 5px;
top: -32px;
color: #ffffff;
content:'Add To My Playlist!';
left: -100px;
padding: 5px 5px;
position: absolute;
z-index: 98;
width: 120px;
height:15px;
text-align:center;
-webkit-transition: all 0.3s ease-in-out;
-moz-transition: all 0.3s ease-in-out;
-o-transition: all 0.3s ease-in-out;
-ms-transition: all 0.3s ease-in-out;
transition: all 0.3s ease-in-out;
filter: progid:DXImageTransform.Microsoft.gradient(GradientType=0, startColorstr='#1e78a0', endColorstr='#1e78a0');
box-shadow: 1px 1px 2px rgba(0, 0, 0, 0.1);
cursor:pointer;
}
Well, to clarify, I modified it to be a standalone element.
CSS
.addtoplaylist-video-link {
position: absolute;
display: none;
background-color: #ffffff;
background:rgba(30, 120, 160, 0.8);
border-color: rgba(30, 120, 160, 0.8);
border-right-color: #ffffff;
border-radius: 5px;
bottom: 15px;
color: #ffffff;
right: 10px;
padding: 5px 5px;
position: absolute;
z-index: 98;
text-align:center;
-webkit-transition: all 0.3s ease-in-out;
-moz-transition: all 0.3s ease-in-out;
-o-transition: all 0.3s ease-in-out;
-ms-transition: all 0.3s ease-in-out;
transition: all 0.3s ease-in-out;
filter: progid:DXImageTransform.Microsoft.gradient(GradientType=0, startColorstr='#1e78a0', endColorstr='#1e78a0');
box-shadow: 1px 1px 2px rgba(0, 0, 0, 0.1);
cursor:pointer;
}
Then added the element to the HTML.
HTML
Add To My Playlist!
Finally, I modified the JavaScript. Originally, you were displaying the content on hover as part of the :after pseudo definition. No true interaction within the JavaScript. When you hover over the .toggle class, the .active class is added to the parent element - .frame. The CSS also includes a style to display the new element when the parent has the .active class. When mousing out of the parent element the .active class is removed and the new div is removed.
JS
$('.toggle').mouseover(function(){
$(this).parents('.frame').addClass('active');
});
$('.frame').mouseout(function(){
$(this).removeClass('active');
});
Additional CSS from the fiddle includes adjusted positioning of the .toggle class elements, etc. Here is the portion to show the hidden element on hover:
.active .addtoplaylist-video-link,
.addtoplaylist-video-link:hover{
display: block;
}

Instead of displaying your text using css, write that in jQuery. Just give hover method for that '+' and inside that hover method try to display the text and give the link for that it will work. Because jQuery will give you facility to add HTML elements dynamically.
