CSS - Plugin For Firefox That Automatically Calculates Px To Em?

Solution included in post below --- thanks.

Hi, I am rewriting a series of webpage in CSS. the pages have a two column
layout with a top area which has a banner effect.

What I would like to do is to have the top and the left div's contain the same info on all pages. So instead of manually putting the contents of these
div's in each page I would like to just create the contents in one file
say top.html and left.html and load them in each page by using some sort of link. This would make any changes to the contents easy, edit one file instead of many.

I am CSS newbie so I would be greatful for any pointers.

Thanks,
R Haynes

I am desperate. I think I found a bug in Firefox, and I'm not sure how to work around it.

The following code works in everything (IE 8, Chrome, Safari, Opera) except Firefox (version 3.6.3). Am I doing something wrong, or is this a bug in Firefox?

You can look what happens to the drop-down menu's on Menu 2 and 3 live by going to my site (deenfoxx dot com slash firefox-bug dot html).

css Code:
Original - css Code #main-nav { background-color: black; height: 40px; } #nav { position: relative; margin: 0; padding: 0; } #nav li { position: relative; float: left; display: table; width: 99px; height: 40px; border-right: 1px solid white; text-align: center; font-size: 10px; } #nav li:hover { background-color: darkred; } #nav a { display: table-cell; vertical-align: middle; line-height: 11px; font-weight: bold; text-decoration: none; color: #fff; } #nav li ul { position: absolute; padding: 0; background-color: gray; top: 40px; left: 0px; } #nav li ul li { width: 98px; border: 0; border-top: 1px solid white; }

     </ul>


 </div> 

The problem appears to be that "#nav li" happens to have position:relative; and a display:table; and "#nav li ul" is position:absolute;. Normally, absolute positioning requires its parent or ancestor position to be set, but when used with the table display, it doesn't work normally on Firefox--but it does on other browsers.

Can someone help me with a workaround that does not involve altering the HTML? If I must, I will accept a workaround that requires changing the HTML, but I'll have to do some heavy duty recoding of Magento's core menu generation. Anyone that knows Magento knows I want to avoid that like the plague--my example is a very simplified version of the problem.

I'm having an issue where a website is showing up a few pixels off in Mac Firefox than it is in PC firefox. Anyone have a quick fix for this?

Mac Screenshots: http://graffetto.com/chops/clairus_screens.pdf

PC Firefox Screenshot:


Firefox, IE, and Netscape all look identical on PC, while firefox, IE and safari look identical on Mac, but different from PC (except safari - messed up text)

Any help is greatly appreciated

Edit: after reviewing my post I realized I was quite vague. What I'm looking for is a way to filter CSS so that only Mac Firefox users will receive one CSS file, and PC users will receive another.

Hi, I'm having an issue with Firefox displaying my home page correctly. It previews smaller than other pages in my site even though they all share the same style sheet.

In IE 7 my site previews fine, the issue is with Firefox for some reason the wrapper seems to shrink on the home page and any help or tips to steer me the right way would be greatly appreciated, thanks.

I have a site using CSS for layout

It has one main div called main-column that sits in the middle of the page
and has a background image. Within this there are 3 columns columns.

the trouble is the background of the main column does not show up behind
these three. If you right click it says there is a background image there but nothing is showing.

my css is:

Code:

#main-column
{
width:750px;
height: 100%;
margin-left: auto;
margin-right: auto;
background-image:url(/site_images/bodyback.jpg);
}

#left-column
{
width:150px;
float:left;
}

#contents-column
{
width:450px;
float:left;
}

#right-column
{
width:150px;
float:right;
}

and html is:

Code:

<!-- Start of main column -->
<div id="main-column">

<!-- Start of Left Column Div -->
<div id="left-column">
<? include("../includes/leftnav.php"); ?>
<!-- End of Left Column Div -->
</div>

<!-- Start of contents Column Div -->
<div id="contents-column">
<? include("../includes/main.php"); ?>
</div>

<!-- Start of right Column Div -->
<div id="right-column">
<? include("../includes/rightnav.php"); ?>
<!-- End of right Column Div -->
</div>

<!-- End of Main Column Div -->
</div>

Any idea how I can correct this?

I have two divs on a page and the last two are about 10 pixels higher up the screen than the last one. But if I adjust the window size they move back down where they should be.

This only happens on of the pages though which is quite odd. Does anyone know of any firefox bugs that would cause this and any work-arounds?

I have a question regarding CSS and it's compatibility with FireFox, the problem is, when I have the CSS in a seperate file (e.g. <link rel="stylesheet" type="text/css" href="content.css"> ) it wont work in FireFox browser, works fine in Internet Explorer, but when I copy and paste the CSS directly onto the page, in between the <head> </head> tags of course, it works fine in FireFox and Internet Explorer fine, what am I doing wrong, do I need to specify something in the "stylesheet type" tag above?

Any help would be great!

My website works fine with all browsers except IE. Can anyone help me with the issue?

www.opennys.com

It uses CSS and xHTML and PHP.

Thanks,
Dennis

Have a page at

www.maxxedmotors.com/damo

There is a div called "container" which is supposed to surround all of the content with a border.

This works fine in IE 6/5.x, but in firefox the border only surrounds the div called "header".

Can anyone tell me where i'm being dumb

Any help greatfully appreciated.

Can someone please help me, i am desparate to intergrate transparency into my forum but im finding out what a pain in the *** it is.

I tried semi transparent png's, but they only work in firefox and IE7 but most people are using IE6 (42.3%). I looked around on the internet for a fix that solves the ie6 png transparency issue but i didnt find one that shows it as semi transparent and doesnt bugger all of the links.

Now ive moved onto CSS, ive found a solution that works great for IE 6 + 7 but not firefox. What happens is i apply a transparent css to the pagebackground:

Code:

	filter:alpha(opacity=50);
	opacity: 0.5;

but it applies it to everything on top as well. To get around this i apply a non transparent css to everything on top:

Code:

	filter:alpha(opacity=100);
	opacity: 1;

This works fine in IE making the background transparent and the contents on top solid but in firefox everything (including the content and the background) is transparent. Is there anything i can do to get around this? Its getting really annoying! Any help you can give would be much appreciated.

preview in firefox and IE.
Lines appear in IE but not firefox
This is related to the display of a text box on mouseover.

why ?? is there a better method ??

my css in IE is GREAT and look good. but on firefox, it doesnt show my background and all that. can anyone give me some suggestions.

I see there is another post here on this. But it may be a different issue. I was hoping some of the experts could take 30 seconds to see why this looks fine in Firefox and not IE.

It did validate at w3c. I am sure there is a hack, but if there is something that sicks out real quick it would be much appreciated. I know everyone gives there extra time here and it is greatly appreciated.

I created a menu for someone, hideous as it may be, it's what they wanted. However, it works in Firefox but not in Internet Explorer.

This is code I used for the menu.
.Menu ul li {
float:left; position:relative; list-style-image:url(images/divider2.gif); margin:0 15px 0 20px; padding:0;
}

I have an image to replace the bullets that would normally appear. In Firefox it appears with the image as it should, but in Internet Explorer it is not showing up like it should.
