I am not sure whether i am missing something here, but it seems i cannot put an imagemap above everything else (in terms of z-index). I tried varying the order of the HTML element definition, i tried using CSS to define proper z-index values, but none of these approaches works.
Has anyone encountered similar issues?
(Tested in FF 8.0.1)
jsFiddle here
You need to add position:absolute; to the map too:

I would suggest setting #testDiv to display:none
Then whenever the event occurs that you want to trigger it appearing or disappearing simply call:
$('#testDiv').toggle();

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>
See Output
Correct me if I am wrong anywhere.
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 am having trouble getting the facebook pop out dialog to be on top of my nav bar and slideshow here:
http://d14599.u62.c14.ixinstant.com
I have search for several hours and all the solutions have not seemed to work. Here is a list of what I have checked:
-overflow:hidden on other page elements causes problems. I looked into this but my nav bar does not have this property.
-z- index only works for positioned elements. I made sure my elements were positioned relative or absolute.
-I tried directly styling the js created facebook elements using things like
.fb_iframe_widget{
display:block !important;
z-index:9999 !important;
}
I'm not that good with CSS but have never been stuck this long on one single issue.
I am assuming the issue actually is with something I have done wrong elsewhere on the page, like the navbar itself, but I cannot see what it is. Any thoughts would be greatly appreciated.
I searched lot of things and tried it too but no solutions worked for me. I found one quick fix to solve facebook like dialogbox overlap issue here and it worked for me.
Hope it could save others time, Cheers!
It doesn't really solve the issue, but what I have done is to hide the comment box. For this case it was acceptable. In the css file I added:
.fb_edge_widget_with_comment span.fb_edge_comment_widget {
display:none;
}
What worked for me was to set the z-index for the element that holds the Facebook like button to be higher than the element the comment box was shown behind.
I'm currently working with a set of links that are getting their background images replaced when they are focused, hovered over, and non-focused; but right now I also need to fix it so that when you hover a focused link you'll get yet another result. My searching hasn't found anything and my experiments with anything like:
a:focus:hover { background:url(image.url) no-repeat;}
have met with less than desired results. Does anyone know of way to simply do what I'm trying for?
This should work, but focus won't work in IE without a valid doctype, so I doubt :focus:hover will fare any better.
Solution found, that method does work; but only when you remember to include the class and sub-class names that you are applying to an item.
I have a label with a tooltip attribute for rollover effect. This works all great. However, it seems to get hidden behind any dropdown lists that are nearby. I have tried adjusting the z-index, without any luck. This issue does not appear in firefox, and I have not tested it in later versions of IE.
I realize this is probably due to IE6s poor css standards-compatibility, but how can I get around this?
Not the best because it requires javascript/jQuery library, but there's a workaround:
http://dhtmlgrounds.wordpress.com/2008/12/23/ie6-select-box-z-index-bug/
IE6 has a know error that selects always end up the highest in the z order...
Custom select control optional?
Have a look at this
Another idea is to use the ajaxtoolkit autocomplete?
The select dropdown in IE6 is implemented as a Windows control, so the browser isn't really drawing it. Thus, it doesn't support features like z-index. One possible solution is to hide all select boxes on the page when you show your tool-tip. Another option is a custom dropdown, which you can find in libraries like Ext.
As astander and MikeWyatt said, selects in IE are topmost. There are two paths to work-around this problem:
Use a custom select box, rendered with divs, etc. This is rather cumbersome, since you won't be able to replicate all of the drop-down functionality.
Place an <IFRAME> under the tooltip (tooltip z-index > iframe z-index). This will work-around the problem, yet you have to worry about the positioning of the iframe overlay.
