I have a bit of a IE8 problem (sound familiar?)
I have a button. when you hover over the button the hover state produces a larger box that has html inside. in this particular case, it's a small music player.
so it goes like this, when you hover over the button it produces a small music player with clickable links and some text. you can move your mouse anywhere inside this box, but as soon as you leave the box/music player, the hover state goes away again.
sorry but I don't know how else to explain it.
this all works a treat except for IE8.
in IE8, the hover state disappears as soon as the mouse leaves the original small button. so navigating around the music player becomes impossible.
now I have noticed that when there is no html in the hover box, it works fine, but when there is html (in this case an iframe) it loses the hover as soon as I touch any html inside the hovering box. so it looks like the problem is not the hover box, but the code inside the box that makes it lose focus
what I would like to know is, is this a known issue in IE8, or could it just be bad coding from my side. in which case i can post the css.
I've had problems with :HOVER states in IE8 too and I noticed that the same CSS (even pointing to the same external CSS file) worked on some pages but not others. The solution for me was to consistently add a DOCTYPE to the top of all pages (above the starting HTML tag).
It seems obvious now, but sometimes (especially when editing old sites) the DOCTYPE is not always specified.
I hope this helps!
Your problem doesn't seem to lie in hover itself. Firstly you assume some window height and your project just look weird if the height is different. Assuming you did some very exact calculations on such assumptions your problem is probably the box model problem. box-sizing:border-box might help, but you would have to recalculate everything.
Also you can use timeout before the elements gets hidden/drop down so that micro mouse movements don't shake elements and maybe allow to "catch" them.
Having both things in mind all hovering problems should be fixable.
EDIT: For iframe hover have a look at: Iframe hover not working in IE (all versions).

Set "Montreal" in the search textbox and hit Enter. The map should go there and show results (after you zoom in one notch I think). A panel will slide from the left for the list of results. This panel has a white arrow attached so that it's possible to collapse/expand it. Here is what happens:
On IE/Firefox: the panel slides well.
On Chrome: the first time the panel extends, it works well. Then any
new manipulation shows the issue. The content of the panel and the
tabs will change position only after the jquery.animate("left") is
finished.
I let you have a look at the css structure under firebug or other dev bar, but basically it seems that chrome doesn't like the various "position:relative" css rules inside the panel. The problem is that I don't control them. They are set by the mCustomScrollbar jquery plugin. To check that this is the actual reason, just zoom out a little until a small window appears notifying that you should zoom in again. This empties the content of the pane and collapses it. See how it closes nicely this time, since there is no content anymore in the pane.
The question is: how should I modify the css (the part I control) so that it works well in Chrome and continues to work well in other browsers?
Let me know if something is unclear, I will update this question.Thanks for your help.
There was no answer here, so I decided to fix it myself by adopting css3 transitions on chrome only. This is now far better but you will notice that the tabs are a bit lagging when the panel slides. This does not happen in non webkit browsers.
Recently I encountered a rendering issue in Webkit which I suspect to be a bug with the Webkit engine. But I am not confident enough to say so. So I would like ask here and see what you think.
It'd be a bit difficult for me to describe the case in plain text, so I prepared a snippet here:
http://jsfiddle.net/2eQXa/1/
First you can see a yellow background with red border. This is not a background of the <body> tag but a <div> with id "backdrop" which has 100% width and height. By default it links to the "backdrop-no-problem" class. Also there is a horizontal list with some images. The list is surrounded by a green border. Inside the list there are some Wikipedia logos wrapped with a dotted red border.
I tested the page with the following 3 devices:
1. Chrome 21 on Windows 7
2. Mobile safari on the first generation iPad (running iOS4, I'll call it iPad1)
3. Mobile safari on the "new" iPad (running iOS5, I'll call it iPad3)
Try clicking "right" or "left" to scroll the list. Pretty good.
To reproduce the my problem, first click on "Issue #1". This will change the backdrop div from "position:absolute" to "position:fixed". Then click "Issue #2". This will add "-webkit-backface-visibility: hidden;" to the element (The reason for adding this style is to ensure smooth animation on the iPad).
Now click "left/right" to scroll the list. You should see a strange behavior in all three browsers:
The green div is scrolling properly and smoothly, but not its child elements. The child elements simply "out-sync" with the position of the scrolling parent. The movement not only looks laggy, it sometimes even stuck. And the child elements will stop at a wrong position when the scrolling animation finishes. You have to move your mouse over the picture (or tap on it in a tablet) to trigger an update to have the element re-drawn at the right place. Even Chrome shows this weirdness makes me feel that it is a Webkit issue.
Things gone worse in iPad3. In iPad3 you don't need to add "-webkit-backface-visibility: hidden;" (Issue #2) to see this weird behavior. Just add "position:fixed" (Issue #1) will do. The strange thing is that this doesn't happen when you view the snippet in jsFiddle. In case you are interested I have put the source in a single file at pastebin:
http://pastebin.com/i4ARX4mD
When writing this question I saw quite a number of questions regarding backface visibility. I've checked some but none of them matches my problem.
Ideas or suggestions are welcome. Thanks!
(Post updated to fix many typos)
I have a site where the background-image jumps up on hover state and I can't for the life of me find the specific css that does this.
I'm able to get to the "offending" link and give it a border and change the padding and margin. The problem is that firebug and chrome inspect does not show me what happens on the hover state.
So I want a way to see what additions to the normal css state happens on :hover.
Any pointers?
(P.S. IE 8 doesn't have this issue - ie no jumping of background image)
Try using the Inspect function in FireBug to focus in on the element in question. It will show you all related CSS, including any CSS that is related to :hover. You can also see in this way what changes happen to the elements CSS (and any other DOM attribute) when you hover your mouse.
In case the changes are coming from some JavaScript, try out the Visual Event bookmarklet. Activating it on the page will let you see all events that are tied to the element in question.
Does anyone know what is causing the sprite rollover to jump around
It is I think more likely a photoshop question, but I am not completely sure.
I hope to get an answer here anyway, since I think most webdesigners/programmers problably worked with photoshop also.
This is what I want the rollover to do example 1
and this is my testpage (see the play button)
I made the sprite with spriteme.com
thanks, Richard
I do not see anything jumping around. However, when I first open the page the Play button is missing (its style is set to display: none;). When I click stop it appears, and then disappears when I click play. This is due to it's inline "display" style being set to block and none.
Is this your problem?
Note: I tested in Chrome and FF. I debugged the CSS states using Firebug.
I am working on this philippedecor.com site and I am having a difficulty in figuring out this css issue.
When I on mouse over on "Main categories" that appears on the right side, it shows a drop down with links in it.
Two things happens,
1) in IE(7) - the drop down hides behind another div
2) in both ie and ff, it pushes other div below that to go down and on mouse out, it looks fine.
I am not sure which css property can fix this.
please help me out

In Firefox, I also see a tiny bit of the background showing through the menu, as you can see. Mousing over this thing triggers a mouseout event, closing the menu. In IE 7, I don't see the push-down effect, only the hiding of the menu under the Flash panel and everything below it.
To prevent the menu pushing down other elements on your page, you should use position: absolute on #downmenu and probably incorporate it into the div containing "Main Categories" to position it in the right place. Use an appropiate z-index will likely prevent the drop down menu from popping under another div in IE (untested, as I don't have a debugging tool for IE at the university where I'm typing this message now).
Furthermore, I think you shouldn't use two menus containing exactly the same content, that can be confusing to visitors of your site (actually, I didn't read your post well enough and moused over the left instance). Also, you shouldn't put text in images without providing alternate texts, screen readers and the like can't "see" it this way (preferably use a suitable image replacement technique). And all those s in the lis are totally unnecessary and not according to rules for semantic HTML; just use padding on them or something. By the way, you should make the rounded cursors of 'Main categories' transparent (now two little white corners are shown). Just my $ 0.02...
