I am using text-shadow for all p and headline tags (2px white glow for better readability), everything works fine until page is scrolled and javascript changes absolute positioning on one element to fixed - which I want to stay visible.
Is there any way apart of changing style for opera to make it scrolled smoothly? overflow:auto is not working in this case...
Thanks
it's hard to say 100% without seeing the code, but I guess that the way you've styled this page makes Opera do a lot of reflowing and painting when it is scrolled, and the combination of styles will make this a very expensive operation. (It would be nice to see a jsfiddle or get a link to the actual page, this would also make it simpler to advice on possible workarounds).
There are various fixes you could try - like keeping the element you want on-screen styled with position:absolute and move it from JavaScript after scroll events, or simply avoid setting position:fixed in Opera and letting the element scroll away for better scroll performance.
However, I'd strongly recommend that you first report a bug to Opera. Why?
The reason and the genesis of the web is collaboration. It may not be obvious to (understandably) frustrated web developers struggling with browser bugs, but they have a responsibility for helping browser vendors improve when they find problems, thereby contributing to moving the web forward. A minority browser like Opera admittedly has less development and QA staff resources, but to some extent support from the user community and "normal" web developers makes up for this and makes it possible also for smaller players to develop in the Web ecosystem. I think that's one of the web's strengths and the real reason why no single corporation has been able to dominate it.
So please report your issues and problems :)
This is a problem with Opera, not any way you've written the code. Opera is a gigantic steaming pile of doo-doo with almost no market share, and you should use another browser.
That's basically all anyone could tell you here, unfortunately. I understand that everyone loves their browser of choice but some just don't handle these things well. Other examples: browser with a poor javascript engine rendering animations erratically and jerky, etc.

So I've been working on browser compatibility. Unfortunately, when I first designed my site, I desigend the CSS aesthetically for Firefox only. Now I'm having all sorts of trouble trying to get it to look good in the other major browsers. However, when I fix the CSS positioning such as floating a box object to the right, IE8 forces it left. I checked my code on W3C and it's okay semantically. I use little to no javascript. It's a portfolio website. The screensize shifts everything around no matter what browser, yet there is no perfect CSS for this so how does one get things to stay in place? I'm not too familiar with JQuery, but this seems to be the closest I can get to an answer. Where would I plug this into my site to see if this works?
I just found out about this really cool plugin (new for me, old for some of you maybe) and it works like a charm upon implementation, but only in regular computer browsers. When I try it on my android phone, the css3 animation of the dropdown moves really really choppy, just like its dropping frames. How can I fix this problem?
Here is the plugin I am reffering to:
http://responsive-nav.com/
They seem to have done a really nice job with the plugin, I would say the largest cause of the drop of frame rate may be because you are repainting the entire screen. If you would like, roll your own side navigation but make it go over the existing web page rather than move all the elements on the screen.
EXAMPLES OF SIMPLER MOBILE NAV without repainting

As a further step you can also get rid of the javascript and just do plain CSS and see how that works for you, an example of using checkboxes and labels to control the side nav can be found on my site (just inspect the code) - www.aktof.ca . Hope this helps!
How can I make my scroll bar black for a <div>?
Is there anything that will work in Webkit, IE7 to IE9 and Firefox?
You cannot do this in Firefox. Only IE and webkit browsers support modifying the scrollbar.
See http://msdn.microsoft.com/en-us/library/ie/ms531153%28v=vs.85%29.aspx on how to do it in MSIE and http://www.webkit.org/blog/363/styling-scrollbars/ on how to do it in webkit.
You cannot style the scrollbar of the browser. It's not universally supported (although IE did try to implement it).
Also, it's a bad idea to do so from an accessibility perspective. Think of (old) people who cannot see your very slim, almost invisible custom scroll bar or don't know that what you have there is actually a scroll bar.
You can use custom scrollbar plugins in JS like this one. It's all over the place
As Pez Cuckow said:
I imagine that custom scrollbar is implemented in javascript, it looks
very slick and you can't make a browsers scrollbar look that good!
Find an example I just put together for you at:
http://jsfiddle.net/9LHPW/2/ - note check the resources tab as this
includes four external files (3x Js and 1x CSS)
Have a look at this website for a further example (looks like exactly
what you want) with Javascript and jQuery:
http://manos.malihu.gr/tuts/jquery_custom_scrollbar.html
You can find the plugin's home at
http://manos.malihu.gr/jquery-custom-content-scroller
Along with a how to use it section!
I agree you shouldn't tamper with the visibility (I'm looking at you Apple) of the scrollbar of a scrollable region. Sometimes, a box with scrollable text fits just inside the boundaries and there is no visual clue letting a user know that it scrolls thereby confusing the user. Is it really a good idea to prevent the user from being able to use your application? Most likely not, but you can also argue back that your target demographic wont have any problems; an application for extreme inline competition is probably not going to be used by people who aren't able to see very well. However there are accessibility/usability concerns that go beyond visual hinderances; cognitively impaired, or non tech-savvy, individuals might be very good at said aggressive inline and want to compete in your upcoming event but wont be able to because the black-on-black scrollbar looks awesome.
That all said, do what make you happy. That's what I do.
I just finished a website: http://www.basenharald.nl and all is good in IE9, chrome and firefox.
It does not support browsers < IE8, but that is planned.
However the website is really really slow in IE8 and for some reason some people encounter that the scrolling divs do not work (not all IE8 users).
Any help on these issues would be greatly appreciated since i cannot locate the problems.
Because IE8 just renders these animations VERY poorly. Also slow PC's will have issues with the animations.
You should detect IE8 (and lower) and disable those effects, because they are not functionally necessary
First of all well done on a good looking site. I have used Developer Toolbar in Chrome to detect the following problem. Your site uses or reference a page called daddy-shoutbox.php. This code in this page or calling code to this page is causing a infinite loop or continues call. From my results I could see that that page takes on aggregate about 500ms to load.
From the browser perspective I can only assume that IE8 actually shows the symptoms of this loop. My stats showed that the page has made over 130 requests and counting after 2mins.
Not modern browsers and, as douwe said, even slow PCs will be affected.
The parallax animation requires lots of CPU time and the effect is mainly related to the aesthetics of the website.
A good compromise between usability and aesthetics could be achieved by reducing the parallax effect.
I suggest you to remove the effect from the text ( class: contentwrapper). It will save you some CPU time and it will give you a more readable text.
You could even switch to a normal scroll bar. For my experience, customized scrollbars, always give some trouble with the users ;)
If you are happy with the experience on the modern browsers, you could simply discriminate older browsers.
With jquery you can use this
good luck
In Opera 11.52 it doesn't load at all..
This may sound crazy, and i didnt believe it until i saw it for myself.
The vertical scroll bar does not scroll when you click in the space between the scroller or the arrows. You have to drag the bar to get it to scroll. This only happens in the ugly default theme (not windows classic).
The scroll bar has some heavy javascript behind it that drive scrolling of another DIV on the page.
Has anyone even encountered this before? Why the heck does the theme influence IE's rendering?! Only IE!
edit:
this problem happens when you are in "non-classic" XP theme (the default ugly one). switching themes does not cause this, but it does fix it if you switch to classic from the default.
Does it help when you add
<!--[if IE]><meta http-equiv="MSThemeCompatible" content="no"><![endif]-->
to your page source? It worked well to work around glitches in IE when a non-classic theme is enabled for me. Note that the conditional comments are there so that firefox does not parse the tag (because it will screw up scrollbars in firefox sometimes).
I just had the same problem with vertical scrollbar in IE7 within the XP theme. After many experiments, I finally found the solution to it. I don't know this solution fits your case.
The container (div#scroll in the example below) with the rendered scrollbars must be larger than 18px. Any number below that will cause the vertical bar disabled.
<div id="scroll">
<div id="fill">
</div>
</div>
The stylesheet, for example:
#fill{
width: 1px;
height: 1000px;
}
#scroll {
width: 18px; /* This has to be larger than or equal to 18. */
height: 50px;
overflow-y: scroll;
}
Thanks,

In order to avoid certain Windows restrictions, IE re-implements almost all the controls visible on a web page.
The Old New Thing : Windowless controls are not magic
<excerpt>
The Internet Explorer team went and reimplemented all of the controls that a web page would need. They have their own windowless checkbox control, a windowless listbox control,
a windowless edit box, and so on. In addition to reproducing all the functionality of the windowed controls, the Internet Explorer folks also had to reproduce the "look" of the
windowed controls, down to the last pixel. (Functions like
DrawThemeBackground and DrawFrameControl prove extremely helpful here.)
If I recall correctly, the only element that is still windowed is the <SELECT> element.
If you squint, you can see some places where they didn't quite nail it. For example, if you right-click in a text box, options like "Right to left reading order" and "Insert Unicode control character" are missing. As another example, notice that IE's scroll bars do not light up when you hover over them.
</excerpt>
Without seeing the code implementing your page, I would guess that this is another manifestation of "IE's controls don't act native".
If you have a support contract with Microsoft, I'd suggest complaining to them through that channel; if not, see if you get any responses in the microsoft.public.internetexplorer.general newsgroup. Back in IE6, they broke the scrollbar with KB824145 and fixed it with KB832894, so it's not like theses sorts of problems haven't happened and been resolved before.
First, I'll start saying that IE is a terrible browser and in some cases you don't have control over issues while developing a web application.
In that case I haven't encounter such an issue and a Google search don't pull anything on the subject. I'd say it must be something in your code that lead to a weird bug. Most likely it won't break in a lot of systems, so unless it's a very important application (sales, government...) you could leave it that way.
Look at it that way: who change the style of windows to classic? Geeks. And do geeks use IE? No. ^^ ... Joking, but not really.
If it's important I'll need to take a look at your actual code for "The scroll bar has some heavy javascript behind it that drive scrolling of another DIV on the page."
