UPDATE: I was able to force the box and text to work by adding a "height" value in CSS but the BG image won't load in. Inspector shows the image is loading from the correct source but it will not display in Firefox. I tried setting the null check to false and droping the "!" operator from the getElementByID code but that did not fix it.
I made a simple typing game that is supposed to create an overlay with a dialogue box that allows the player to either go back to the selection page or repeat the game. The dialogue box displays just fine in Chrome and Edge (IE) but in Firefox the Inspector shows the box div as collapsed to 1px height.
here is the code:
HTML
...
<div className="overlay" id="overlay_2">
<div className="dialog">
<div className="dialogcontainer">
<img className="dialogbg"/>
<h3 className="dialogtext">Would you like to repeat this quest?</h3>
<h2 className="no">Go back</h2>
<h2 className="yes" onClick={repeat}>Repeat</h2>
</div>
</div>
</div>
...
JS
function endGame() {
var end = document.getElementById('audio_end')!;
(end as HTMLAudioElement).play();
document.getElementById('overlay_2')!.setAttribute("style","display: block; opacity:1; -moz-opacity:1; filter:alpha(opacity=100); z-index: 20");
}
CSS
.dialog {
position: absolute;
left:50%;
top: 50%;
transform: translate(-50%, -75%);
}
.dialogcontainer {
position: relative;
text-align: center;
}
.dialogbg {
position: relative;
width: 500px;
content: url("/Images/Video%20Page/dialog.jpg");
}
.dialogtext {
position: absolute;
width: 70%;
top: 50px;
left: 50%;
transform: translate(-50%, 0);
}
.yes {
position: absolute;
width: 40%;
bottom: 30px;
right: 30px;
cursor: url('/Images/Main%20Menu/mouse2.png'), auto;
}
.no {
position: absolute;
width: 40%;
bottom: 30px;
left: 30px;
cursor: url('/Images/Main%20Menu/mouse2.png'), auto;
}
.yes:hover, .no:hover {
color: #555;
}
The black translucent overlay works fine in Firefox but the box does not show. I have disabled all ad-blockers in Firefox but that wasn't the problem. Any help is greatly appreciated.

there. I was trying to make a hover popup. When my mouse hovers over a table header, a detail explanation will pop up.
However, when I scroll left the table, the popup stays. Is there any way that I can make it stick with the header?
Jsfiddle Link:
https://jsfiddle.net/fmchen/hmaczn87/10/
Some Screenshots:
When scroll left:
I know that I can change the position: absolute; to position: relative; in .CellComment1
However, it will be looking like this:
I added the position: relative; to the field_29 class, then position: absolute; to the span and it worked properly. If you want to be in 1 row then add the span a width: max-content; and for the center align add a margin-left: 50%; and transform: translateX(-50%);
.field_29:hover span.CellComment{ display: block; position: absolute; width: max-content; margin-left: 50%; transform: translateX(-50%); }
.field_29 { position: relative; }
Im currently in the process of fixing a wordpress site for a client, unfortunately I am having tons of issues with scrolling on one of the pages. I have tried time and time again to remove any scroll assist js that could be causing it but I still cant seem to get it to work.

You issue is background-attachment
Chris Ruppel writes:
[...] using background-attachment: fixed causes a paint operation every time the user scrolls. Why? Well, the page has to reposition the content, and then, since its background image is supposed to appear as if it’s holding still, the browser has to repaint that image in a new location relative to its actual DOM elements. The performance for this feature is so bad that iOS simply ignores this property.
The culprit is your header background image.
it is fixed and is consistently getting repainted on scroll behind your page content.
In you CSS file you have this
.section-parallax {
background-attachment: fixed;
}
If you remove that then you smooth scrolling without trouble but you loose the parallax effect.
If you must have the parallax effect then you need to either use a more efficent method for the effect or hack your way to it.
for more efficiency use jQuery. I found a pen by Marcel Schulz and copied it below for reference:
/*
See https://codepen.io/MarcelSchulz/full/lCvwq
The effect doens't appear as nice when viewing in split view :-)
Fully working version can also be found at (http://schulzmarcel.de/x/drafts/parallax).

In the same article I quoted above, there is a tutorial for how to fix the issue with CSS. Instead of using background-attachment: fixed you add the background to a pseudo-element and give it postion fixed like so
.element {
position: relative;
}
.elemnt:before {
content: ' ';
position: fixed; /* instead of background-attachment */
width: 100%;
height: 100%;
top: 0;
left: 0;
background-color: white;
background: url('/img/front/strategy.jpg') no-repeat center center;
background-size: cover;
will-change: transform; /* creates a new paint layer */
z-index: -1;
}
And this will essentially limit the impact on scrolling as the "background" would have it's own independent element.
Note: If you run into issues which you cannot debug, open the dev tools and start deleting elements from the page one by one until you find the issue.

From looking at your site, there are a few parts of it that are slowing down the rest. Here are a few easy ways to speed it up.
Use a CDN
A CDN (Content Distribution Network) ensures that everything is loaded faster because it doesn't depend on your own Wordpress server and will allow access times to be consistent across the world. There are a few good ones out there like CloudFlare and Incapsula. Here is an article listing a few more.
In addition, you can host your images (I see that one is coming from Wikipedia) on a slightly faster
Compress images
This step is as easy as converting photos to a .jpg. JPEG automatically compresses the data by getting rid of unnecessary information in the photos. You can also use compression software to get the file size down.
Leverage caching
Use a caching plugin (there are tons of great ones for Wordpress) to cache data on your server and can really speed up things for your site.
Search for more ways to optimize
Use tools like Pingdom and Google PageSpeed Insights to identify bottlenecks and resolve them.
Hope this helps you!
Is it possible to give the hover-icon a class, so that the icon is the triggerinfo? The image is in gray when i hover it, it gets colored but I wan't to hover a text when is colored, when I going over the little icon. Is there a way overlapping the div with the triggerinfo class over the image, but not leaving the hover of the image. Like hover the div that is not visible and not leaving the hover effect colored ?
Thanks !
If it helps I can share the link to my website, but only as message not for the public post. It gets more visual, and I think better to understand what I mean.
jQuery(document).ready(function() {

jQuery(this).next(".info").toggle("fade");
});
});

The Fiddlejsfiddle.net/e8qd8gvf/3/ works now as it should on my site. Now the thing is: on hover the img get colored and it appears a little icon in the bottom left coner, the trigger that is now under the img should be this little icon, because the icon is from the css definition in uk-overlay-icon (from the font awesome)
I dont now how to set the info class on this icon.
Or I was trying put an div with the info class over the img at the position of the icon and than trigger it, but than the colored effekt dont show when I trigger it, so I thought there must be a way to trigger the div on hover and not lose the colored effect, so the trigger div would trigger the Info and musst trigger the hover from the img at the same time
PS: Sorry for the long css !
The <figure> element is intended to mark up diagrams, illustrations, photos, code examples and similar content, "that can be moved away from the main flow of the document without affecting the document’s meaning" (http://w3c.github.io/html-reference/figure.html).
Your way of using it seems to be against this specification.
It's your own responsibility to code according to specification and best practices.
I just opted with your provided example: https://jsfiddle.net/e8qd8gvf/4/
I moved the uk-overlay-icon outside of the figure, added the toggle-info class and put the info box inside it.
All that was left was adding some CSS:
.uk-position-cover { cursor: default; }
.uk-panel-teaser { position: relative; }
.toggle-info {
display: none;
cursor: pointer;
position: absolute; bottom: 20px; left: 20px;
width: 30px; height: 30px;
}
.toggle-info > .info {
width: 150px; height: 150px;
border: 2px solid red;
position: absolute; bottom: -20px; left: 10px;
transform: translateY(100%);
}
.toggle-info, .info { display: inline-block !important; }
.toggle-info.hidden, .info.hidden { display: none !important; }
as well as changing your JS to:
jQuery(document).ready(function() {
jQuery(".uk-overlay").hover(
function() {
jQuery(this).next(".toggle-info").removeClass("hidden");
},
function() {
jQuery(this).next(".toggle-info").addClass("hidden");
}
);
jQuery(".toggle-info").hover(
function() {
jQuery(this)
.removeClass("hidden")
.children(".info").removeClass("hidden");
},
function() {
jQuery(this)
.addClass("hidden")
.children(".info").addClass("hidden");
}
);
});
My solution is only showing you a way to accomplish things and is by far not "nice". You need to adapt it yourself and to specifications.
I'd like to make an image viewer that centers an image regardless of how big it is and allows scrolling to view the entire image.
The problem I'm running into is that, while centering images smaller than the container is easy, when they're larger tranform I'm doing positions the image off the right and top of the screen.
Here is the fiddle that has some fixup javascript to make it work: http://jsfiddle.net/d3y0b8bd/
The code below will work for smaller images (e.g. https://upload.wikimedia.org/wikipedia/meta/0/08/Wikipedia-logo-v2_1x.png)
But for larger, the translate(-50%, -50%) transform will translate the image past the left and top margins of its parent.
.lightboxRoot {
position: fixed;
width: 100%;
height: 100%;
overflow: auto;
/*aesthetic*/
background-color: red;
}
.lightboxImg {
position: absolute;
top: 50%;
left: 50%;
margin-right: -50%;
transform: translate(-50%, -50%);
/*aesthetic*/
background-color: blue;
}
html:
<div class="lightboxRoot">
<div class="lightboxImg">
<img id="imgElt" src="http://upload.wikimedia.org/wikipedia/commons/6/65/Cute_beagle_puppy_lilly.jpg"></img>
</div>
</div>
here's a fiddle in which JS is updating the position of scrollTop and scrollLeft, so to set the scroll to center of img.
Figured it out, in retrospect kind of silly: Just make a containing div that can't get any larger than the parent element, and make sure that it has the overflow property set so it gets the scrollbars. then the image inside can get is big as it wants: http://jsfiddle.net/abrady0/d3y0b8bd/2/
.lightboxRoot {
position: fixed;
width: 100%;
height: 100%;
/*aesthetic*/
background-color: red;
}
.lightboxContainer {
position: absolute;
top: 50%;
left: 50%;
margin-right: -50%;
transform: translate(-50%, -50%);
max-width: 90%;
max-height: 90%;
overflow: auto;
/*aesthetic*/
background-color: blue;
}
and the html:
<div class="lightboxRoot">
<div class="lightboxContainer">
<div>
<img id="imgElt" src="foo"></img>
</div>
</div>
</div>
one thing to fix in this case is that I'd still like the div's scroll centered with pure CSS, but this is a good first step.
I'm working on this website called http://martindue.dk/mmd3x9x/ and I have this scroll to top script that just won't coorporate. I've used the script on many other sites, and it works fine, but on this particular website the div#to-top keeps on re-appearing, even though I'm at the very top of the website, why won't it fade out correctly when at the top?
My code looks like this (the #to-top is insertted after the body-tag in my html):
Javascript
jQuery(document).ready(function() {
$toTop = jQuery("#to-top");
$toTop.hide();
jQuery(window).scroll(function() {
if(jQuery(this).scrollTop() != 0) {
$toTop.fadeIn();
} else {
$toTop.fadeOut();
}
});
$toTop.click(function() {
jQuery("body, html").animate({ scrollTop : 0 }, 500);
return false;
});
});
CSS
#to-top {
background: url("img/to-top.png") center top no-repeat;
background-size: 100%;
width: 50px;
height: 50px;
position: fixed;
bottom: 60px;
right: 60px;
cursor: pointer;
/*display:none;*/
/*opacity: 0.0;*/
}
I created this fiddle, and here it works fine: http://jsfiddle.net/2Rubp/
I know it is not js but in this case you are only using fading so css can do the trick:
#to-top {
background: url("img/to-top.png") center top no-repeat;
background-size: 100%;
width: 50px;
height: 50px;
position: fixed;
bottom: 60px;
right: 60px;
cursor: pointer;
**-webkit-transition: all 0.5s linear;**
display: none;
opacity: 0.0;
}
