CSS - Scroll Help With Absolute Position And Hidden Overflow
Title sounds a bit contradictory, I know, but please bear with me...
I'm building a simple chat application with html, javascript php and mysql. The technical stuff (php/ajax etc) i'm absolutly fine with; what I'm struggling with is the CSS to make it behave how I want. I've got a prrof-of-concept page working 90% how I want, here http://chris.loyaltymatters.co.uk/chat-demo/ This works by having an outer div of position:relative and an inner div of position:absolute; bottom:0px so that as new content gets added to the bottom, older text goes up. So far so good....but I want a scroll bar so that I can scroll up to see previous comments. Giving the inner div a height value gives me a scroll bar, but the position remains at the top and new content gets hidden towards the bottom html: Code: <div id='container'> <div id='chatRoom'> </div> </div> css Code: #container {
width:500px;
height:500px;
margin:50px auto;
border:1px solid black;
position:relative;
overflow-y:scroll;
overflow-x:hidden;
}
#chatRoom {
position:absolute;
bottom:0px;
margin:5px;
width:100%;
}
To summarise, all I need now is a scroll bar so that I can scroll up many thanks in advance Similar TutorialsHello people I'm trying to enable a scroll on a div with position absolute but with negative pixels on the left atribute. Something like this: .intro{ position:absolute; top:100px; left:-190px; } the div will start from the back and it's content won't be seen without a scroll.. I've tried with the overflow:auto; but it doesn't work.. i think it only works to the right and not to the left Can anyone help me ? By the way, whats the diference between these declarations on a css: .intro{ #intro{ intro{ I have having issues with IE displaying my page wrong. The page is http://]http://tampabay-online.org/cetr/about.php (or any page within that site) and the css can be found at http://tampabay-online.org/cetr/cetr.css It displays fine in Firefox and Opera but IE makes the content class lower from the top than the #right navigation bar (they should both be 20 pixels form the top) Any help much appreciated. Code: .content {
position:relative;
width:320px;
margin-left: 125px;
margin-top: 20px;
border:1px solid black;
background-color:white;
padding:10px;
z-index:3;
}
#right {
position:absolute;
width:200px;
top:20px;
left:500px;
border:1px solid black;
background-color:white;
padding:10px;
z-index:1;
}
This is working fine in FF, but IE ignores it. I have large bottom margin and large negative bottom padding contained in a wrapper with overflow set to hidden, to keep my columns the same length for different content, which seems to be ignored in IE. Other than that I'm pretty happy with the site, but I don't really know what I'm doing, so I don't really know what I'm doing wrong.. Can anyone help? Structure; Code: <div id="divBranding">
</div>
<div id="divWrapper">
<div id="divSidebar">
</div>
<div id="divContainer">
</div>
</div>
<div id="divFooterWrapper">
<div id="divInfo">

I am having trouble with the overflow: hidden; in IE6. I have a simple example. I have rewritten this to make it as simple as possible. [code] <html> <head> </head> <body> <div style="position:absolute; top: 100px; width:200px; z-index:1; bottom: 113px; overflow:hidden"> <img src="images/700/900-pixel-height-image.jpg"> </div> </body> </html> This simple page works fine in Firefox but in IE6 the overflow:hidden does not work. Why? I thought IE6 completely supported overflow. Is there a way to have overflow content of a DIV hidden at the top of the DIV instead of the bottom? For instance, if I have a DIV that is 200px in height and the content within the DIV ("My top content ... my bottom content.") exceeds 200px: Code: <div style="height: 200px; overflow: hidden;"> My top content<br><br><br><br><br><br><br><br><br> My bottom content. </div> I want the "My bottom content." to always show at the bottom of the DIV, but the "My top content..." to be hidden. I hope this makes since. Thanks! -Chris For some reason overflow hidden is not working in chrome, ff and ie both seem to work as expected. I am totally lost here? Code:

Overflow:hidden, is supposed to expand a box (unless a height is set) to it's contents (just another quirky, stupid CSS rule). I have this working on all browsers except IE6 in one area. I've placed a green box around the problem area, which is the footer of this page: http://www.poweredpages.com/newtarget/ctia/ You'll see it looks fine in most places but is a skinny line in IE. I need it to render correctly because it has some padding attributes. Here it is in the css file: .footer{ padding:10px 35px 10px 35px; overflow:hidden; } Any thoughts why it's not working in IE6? Does anyone know why overflow:hidden does not work when height is given in percentage? The following example does not work and all values from 1 to 20 are shown on screen ... Code: <div style="overflow:hidden;height:10%;border:1px solid green;"> 1<br /> 2<br /> 3<br /> 4<br /> 5<br /> 6<br /> 7<br /> 8<br /> 9<br /> 10<br /> 11<br /> 12<br /> 13<br /> 14<br /> 15<br /> 16<br /> 17<br /> 18<br /> 19<br /> 20<br /> </div> Changing height:10% to height:50px makes the overflow:hidden works fine. Does anyone know how I can make the overflow:hidden css rule with height rule given in percentage? While trying to get text-overflow: ellipsis going with list items, I noticed that bullets were disappearing in Webkit (Safari and Chrome) and Opera browsers. I narrowed the problem down to overflow: hidden. I understand why putting overflow: hidden on a list item can hide the bullets (firefox also hides them in that case), but I'm putting it on a div inside the list item, and the bullets are still going away in those browsers (firefox and ie still show them, but not webkit and opera). This illustrates what I'm trying to do: http://sethsticco.net/files/possiblebug.html ..and this narrows the problem down to overflow: hidden: http://sethsticco.net/files/simpler.html The first list is normal, with no styling. The second one has overflow: hidden applied to the <li> tags. The bullets disappear for firefox, webkit, and opera, but not ie. The third list is the important one. It only applies overflow: hidden to the <div> tags inside the <li> tags, but bullets still disappear for Webkit and Opera. The fourth list is only there to show what happens if I try using <span> tags. They act like divs when they get display: block, and they don't get the ellipsis when they're inline. I feel like I've found a bug, but regardless, I really just want to get text-overflow: ellipsis going on list items. Does anyone have any ideas? I had a problem earlier with my containing DIV pushing too wide which was resolved by adding "overflow:hidden" to my containing DIV. The problem is now that it's cutting off the sides of one of my graphics. At the bottom of my page, I have a link which you can click that will (through the magic of javascript) reveal divs on either side of my main content (the link at the bottom of the page says "reveal sea creature") When overflow:hidden was NOT on my containing DIV, I had the problem with all the extra space, but these revealing divs worked fine. Now that I add overflow:hidden, the extra space is gone, but the divs are cut off. I've tried pushing everything to the left which seems to make the DIV on the right work fine, but the left is still a problem. I realize this doesn't make sense without code, so here's the site. www . deepwaterchurch . com Thanks so much. Hello, I have a problem appearing only in IE8, but I don't seem to find the exact bug and solution. In this page http://www.cracowflats.com/index.php/search/show/id/181 there is a Details area (bottom left) where titles have a green background. For some reason this green background appears in other parts of the page. In other browsers, the whole page has a white background, as it should. 1) With this code in theme.css a {color:#62860b; } h3, h4 { color: #70af1d;} .color_title { background: #76a637;color:#fff;} .logo h1 a { color: #62860b !important;} it appers everywhere and the whole background of the page is green (should be white). 2) when I add an "overflow: hidden;" here .color_title { background: #76a637;color:#fff; overflow: hidden;} it gets better, as the main area is white. But I still have a lot of green on the footer (and tabs). If I could find out to which bug it refers, it would be easier to find a solution. Any hint would be appreciated! Thanks! Luca Hello all I have an elastic design in which an image clips to the appropriate size via overflow: hidden. Is there any way to control which sides are cropped? What I mean is, can one emulate the background-position property for IMGes with overflow: hidden? Thanks Tom when you put overflow: auto; into a div it adds a horizontal scroll bar in, is there a way using css and/or html to make it add a vertical scroll bar instead of a horizontal one so when the text got to the end of the div instead of extending the div it just adds a vertical scroll? Thanks in advance! I want a fixed height table, so I'm using overflow: scroll for the tbody. This works well in Firefox but does not work in Opera or IE. Does a solution exist to my problem? Hello, after a few hours I managed to identify the CSS element responsible for this problem. However so far I have no solution on how I could solve this problem. Basically the problem is very minor but still frustrating. I am using the following command to set a DIV element with transparent background; Code: filter: progid:DXImageTransform.Microsoft.gradient (gradientype=0,startColorstr='#60ff0000', endColorstr='#60ff0000'); The DIV element becomes transparent. However the parent element - which is set with the CSS attribute overflow:hidden - is always displaying an extra pixel on the right of the container. This might not be clear at first, which is why I attached the following screen shot. (the light red line is the extra 1px I am referring to) If I remove the transparency CSS attribute for IE8 then this extra 1px will disappear. However that means loosing the wanted transparency. I have also developed the following example of the problem; Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"

Does anyone know what's causing the problem and how I can solve it. It is true that 1px might not sound much. But it still frustrates me knowing that it is there and the fact that on Firefox all works great. Hello everyone, relatively new web developer seeking help! I'm working on a template that will eventually be used with Joomla, but right now I'm just concerned about getting the layout to work with just the HTML and CSS. I want to create a fixed frame around the webpage that expands and contracts to fit different resolutions and browser window resizing, and then have the content scroll inside of that frame. The frame is also comprised of transparent PNG's since the client wanted lots of art on the frame around the content. It mostly works in Firefox, and is a giant mess in IE at the moment. I'd like to get it working in the standards compliant browsers first and then figure out some hacks that I can use for IE. Hopefully I can do that.... Here is my HTML: Code: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <HTML> <HEAD> <TITLE>Site Test</TITLE> <META NAME="Generator" CONTENT="EditPlus"> <META NAME="Author" CONTENT=""> <META NAME="Keywords" CONTENT=""> <META NAME="Description" CONTENT=""> <link rel="stylesheet" type="text/css" href="site_test.css" /> </HEAD> <BODY> <div id="wrapper"> <div id="frame_left"> </div><!--End frame_left--> <div id="logo"> </div><!--End logo--> <div id="content"> <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.

overflow: auto;
}
In FireFox everything works and the scroll bar pops up, but won't actually scroll anywhere, even though there is content off screen? Any thoughts? I am slightly concerned that this is just totally undoable, but then I look at some of the stuff on CSS Zen Garden and think that there must be a way to pull it off! Any help is very, very much appreciated. Here's my next IE challenge (or frustration). It deals with the overflow attribute. Overflow property was a challenge on my page since the page emulates position fixed for IE. The present scenario deals with the pre element. Sometimes the content in the pre container exceed the parent container's width. IE expands the parent containers width as a result. The workaround for this scenario relates to the overflow property and using a wrapper with the height set to 1% . Now, IE maintains the parent container width. Apparently, the wrapper ensures that IE renders hasLayout. I am not exactly sure why it works, but it has predictable results. The workaround involves wrapping a pre element in a div, WrapOverflow. Now, you could set the overflow auto attribute on the child pre element. Apparently, the wrapper ensures that IE renders hasLayout. I am not exactly sure why it works, but it has predictable results. Firefox has no need for the wrapper and still renders the page accurately with the superfluous code. The problem relates to IE rendering pre/wrapper with a smaller height. By controlling the horizontal expansion; the workaround has somehow constrained the height as well. The net effect is a vertical scroll bar, which is not ideal. Compare the scenario in both Firefox and IE; set the browser next to each other; notice the div.WrapOverflow pre container height. Screenshots are below and review the code for a full illustration. Yes, you must be thinking change overflow auto to overflow vertical. Let's not jump to a quick conclusion. Understanding what is going on here is important as well. The pre container's height should grow in IE, but the page's complexity and various hacks muddle the scenario. I have already spent a month on this scenario, but do not have the skill to decipher what various hacks impose on my layout. Let me know if you have any good ideas, explanations, or suggestions on this situation. http://neville.f2o.org/nifty_TEMP2.html Aloha, Is there any way to make overflow: auto & overflow: scroll use the wheel mouse on mozilla / mozilla firefox ? Here's my design for any of you who might be confused about what i'm asking: http://ub3r.net/oxiserve/ . Thanks. love, mikey |
