I've followed the tutorial url to get a popup working:
I have one caveat though. Sometimes the pages it will be popping up from are really, really long. The code in the tutorial has it popping up in the center. Vertically, this is not acceptable. I'm trying to get it to pop up in the center, but at the very top. I've used top: 0px; and for testing purposes left: 0px; (and a few others) but it seems to matter not. Always pops up in the center.
You can take a look at the latest one I've done here
Am I missing something?
Your technique is very old and not the right way!
What happens in your case is, you have considered the page's height and width for calculating the center position. If you can change it like:
popUpDiv.style.top = '10%';
Just give a try and let me know.
Best Suggestion: Use jQuery! :)
But, what I have followed is from Queness, which is still more simple.
Tutorial: Simple jQuery Modal Window Tutorial and Live Demo.
Hope it helps! :)
In your css for #popUpDiv do top : 0 !important and you will find your popup box at the top. It is because javascript is calculating the top position and its overwriting your css style. Hope this helps.
The problem is your top and left values are being ignored in the CSS because whatever script you're using to make the popup happen is applying the styles inline directly to the popup. So you should look through that script and find where it's applying the styles, then change it there.

At first, it looks simple, and at the end of scroll event, a margin (or padding) will be applied at the top.
This is useful when there is a sticky element at the top. Then when a link is clicked and scroll down to somewhere on the page, it's nice to have this element "skipped" by the scrolling.
This article explains it pretty well: https://css-tricks.com/fixed-headers-and-jump-links-the-solution-is-scroll-margin-top/
I could make it work on really simple examples, and that works. However, I am trying to make this work on a normal website, and I can't. I think there is something not clear for me (or in general?) about how it works.
Please have a look here: https://meowapps.com/media-cleaner/tutorial/#Media_Library_Scan
When a link is clicked on the right, it scrolls but the scroll-padding-top is completely ignored. I have tried many techniques, moving the CSS property in many different places in the code, but that doesn't do anything.
Do you see what's wrong? Ideally, it would be great to find real the cause and maybe have an explanation why it doesn't work in this case and describes what's that case actually is.
Thanks a lot :)
scroll-margin is not useful if scroll behavior is controlled by JS
Looking at your page source, I found easy-table-of-contents WordPress plugin, which relies on smooth-scroll jQuery script. Also, I don't see scroll-behavior: smooth; in your body either (see this MDN page for reference).
It looks to me that your anchor link is not controlled by CSS but by JavaScript. And, as you'd know, when something is controlled by JavaScript, any relevant style declaration via CSS might be ignored.
What to do?
I honestly don't know. Perhaps you could replace the table of contents plugin with something that gives you a finer control. Perhaps you could refactor the said plugin yourself. In any case, should you need to keep the jQuery dependence and a particular WP plugin, you might have a tough luck for this fix.
I got your point, sorry for a long answer but I am sure this will clear your doubt with the output.
scroll-margin-top and scroll-padding-top define the amount of space to be given from within the element or from outside the element whenever a scroll event occurs.
Sometimes we see some text gets cut from the viewport such that it's half visible.
To avoid that kind of thing scroll-margin-top is helpful.
when no scroll event happens:
when scroll event happens but with scroll-padding-top:20px;
see an example from MDN Web Docs
Now applying this logic to your link example
When we click on the link it takes us to the specified div,
But when the scroll-padding-top is applied the output looks like this it gets stuck to the top of the viewport, even if we specify a certain margin with CSS the output is the same because the padding is applied from within the element:
When we apply scroll-margin-top we get the desired output on the link click event or scroll event:
a{
font-size:30px;
text-transform:capitalize;
}
#down{
scroll-margin-top:30px;
background-color:royalblue;
height:100px;
width:50%;
}
<center>
down
<section style="height:1000px;"></section>
<div id="down"></div>
<section style="height:1000px;"></section>
</center>

Correct me if I am wrong anywhere.
I know this has been asked many times, and I have been searching for the answer in a lot of places but I can't seem to fix my code. Thank you for reading this because I'm going crazy here! First I had a different z-index problem with safari, than another with explorer, but now the z-index problem I'm having with mozila I can't fix in any way. I code in chrome, where it seems to work perfectly (for me it seems at least!)
I believe now it works more or less fine in most browsers but not on mozila. The idea of the page is to make (only with CSS because that's the only language supported by the website) a flipping book of several pages. I see some examples around of CSS only flipping cards (only one page), but not a book of more than one page. So I essentially overlap several "cards", in order to give this effect. You can see the demo from codepen here: pkrein/pen/qBOewem
Btw I do know this code is not as clean as it could be, but that's the way I figured to make a fuction like that works only with CSS, and I hope it will make sense for you.
Ok, so the matter is, the content inside the book pages is not "scrollable" on firefox. I guess this is indeed a z-index problem, because when I move any page outside the book, that is, from behind the rest of the content, it scrolls fine.
Let me know if I can give any more info that could help you understand my issue!
I figured a possible solution for this. It's not quite the solution for the problem itself but it's something that can make what I want to do work.
The problem was: (what I had to remove in order to make it work):
(1) The div #content-holder holding all the text inside the flap
(2) The div .preparation-text inside the .preparation (that's the text I want to scroll). That was a scrolling div (.preparation) inside a non-scrolling div (.preparation-text). I always add a scrolling div inside a non-scrolling div in order to hide the scrollbar, by adding a high padding-right to the inside div. I know I can use code to hide the scrollbar but it do not work in all browsers.
How I fixed:
(1) I just removed the #content-holedr divs, since it was not strictly necessary.
(2) I removed the .preparation-text and transformed .preparation into a scrolling div. Then I just covered the scrollbar with an image of the same size and colors as the background (a print of the layout).
I'm clueless how to get the scrollbar display below the active box - list item.
After searching I have found that the z-index should work on element positioned other than static. But still I'm still unable to produce the desired effect.
This is just one part of my problem, I believe if I understand the solution to this one, I can also fix another similar problem.
Somehow the active box is displayed on top of the scrollbar, but not the scrollbar's handle.
Here's the JsFiddle. Should be quite easy to notice my problem.
The desired effect is that the scrollbar and everything related to it (handle) is displayed below the active(longer, red) box.
Sorry, don't really see a way to accompany this problem with code inside the post or how to make the JsFiddle with less code.
I think you'll have to apply a z-index to the .scrollbar element itself, rather than its child .scroller. Add these styles to your definition of it:
.scrollbar {
z-index:-1;
position:relative;
}
And you should get (what I hope is) your desired behaviour. Here's an updated JSFiddle for you to see what this achieves. If this isn't what you were looking for, feel free to let me know and I'll be happy to help further. Good luck!
I'm having trouble figuring this one out, it's a menu I am changing a bit to make it more usable on touch devices. Thus I need the first part of the CSS to stay as it is for normal screens, and then have to overwrite it with the touch styles. But I am trying to position the sub menu of services below services when services is selected. See the sketch. I have created a fiddle to show my problem.
My main problem, and what would solve it, is that I can't seem to get the ul.level_2 to position itself under the selected li, neither with absolute position or floating and clearing. Any ideas?
JS fiddle of problem
I sipmlyfied your example a bit to show you what is the minimal required css to achieve this. http://jsfiddle.net/3EKAq/10/
The positioning of the submenu should be fairly easy, it goes almost automaticly, no positioning required as you can see.
I think the key lies in the clearing of the menu element you want to appear on the left, the 4th one in this case. You could also consider working with the :n-th child css3 selector, but i would not do that for cross browser compatibility.
Hope this puts you in the right direction. Feel free to let us know if you need any more help!
I've done this in the past using a method similar to this:
http://javascriptkit.com/javatutors/static3.shtml
but I don't like the "flicker" effect as the page is scrolled and the div needs to move with the scrolling. Lately I've seen a lot of site that have an element (a div or the like I presume) that don't move when the page is scrolled but it's seemless...they're just there and it's a beautiful thing.
Unfortunately I can't seem to recall where I've seen it lately to view the source and try to figure it out so I figured I'd turn here and see what all of you experts can provide as far as assistance / suggestions.
TIA
Try setting "position: fixed" to the element.
I think this does not work with some IE versions, you'll have to us JS for that.
That site you linked to still mentions thing such as IE 4 on it, better no rely on it. It's outdated.
You can position an element to a fixed position with CSS, by doing position: fixed;.
Take a look at google reader.
It has a fixed header and a fixed side bar.
