I'm having hard time with Xhtml Strict 1.0 and Css. And I'm almost out of solutions.
My Site Url: http://www.pro-turk.net/beta/
I made a jquery multilevel dropdown menu for my site.
It looks like OK, but I have used inline-block property of css display attribute on navigation menu which is a part of css 2.1 and isn't supported by some browsers (including ie6 and ie7).
I want to make #nav > li elements block level elements, but to do this and having all of them in same line, the only way is using float in #nav > li. But I want to center them in their parent (the menu bar). So I need something like float:center (I know it's pretty stupid and doesn't exist). But is there a way to include block level elements as children elements without linebreaks (I mean without making a block level element).
Regards.
I think there is no solution for it in css2 without using tables.
You can make li float left or right and make the menu itself centered. Make the menu the width of the sum of its elements.
#nav
{
width: 500px;
/* This will center the block within its container */
margin-left: auto;
margin-right: auto;
}
EDIT: Since you don't know the width of the menu (it's dynamic) we're coming to the very case when there is no alternative to tables.
<table border="0" cellpadding="0" cellspacing="0" style="margin: 0 auto;">
<tr>
<td>Menu item 1</td>
<td>Menu item 2</td>
<td>Menu item 3</td>
<tr>
<table>
P.S. There is some substitution for tables with newer CSS3 extensions like display:table | table-cell etc., but it doesn't have a wide-spread support yet.
display:inline-block isn't supported in IE6 or IE7, but you can get the same effect in those browsers by using display:inline and ensuring that hasLayout is set on those element by, say, using zoom:1. Use conditional comments to direct the different css to those browsers only.

Is it possible to apply position: sticky to <thead> or first <tr> tag to make table header stuck at the top of viewport while scrolling the table body?
Yes, it is possible to apply position: sticky to thead or tr elements. The position property can be applied to
all elements except table-column-group and table-column
But no, it won't behave like you want:
The effect of position: sticky on table elements is the same as for
position: relative
No. The specification abstract explicitly states:
Other kinds of layout, such as tables, "floating" boxes, ruby annotations, grid layouts, columns and basic handling of normal "flow" content, are described in other modules.
I'll provide direct link for people who wants to see it live.
Just hover one of the table listing and you'll see there is always a small space under images. I've tried padding, margin, searched stackoverflow for it and used border spacing, border collapse etc. but nothing helped so far.
I would like your help. What's the problem and what am I missing?
Problem isn't the table actually, img tags are inline elements and have that bottom spacing by default (something with line-height I guess, don't really know why).
Solution: div.browseBuilds tr.browseBuilds_piece img { display: block; }
Add display: block to img.
.browseBuilds_piece img{
display:block
}
See this similar question. Because img is an inline element, whitespaces in the HTML source code around the img tag matter and will be displayed. Either remove the whitespaces from the code
<td style="vertical-align: middle;"><img src="./themes/default/images/builds/eski.jpg"></td>
or display the img as a block element, as Michal has pointed out.
User cellpadding="0" and cellspacing="0" as a table attribute.
<table border="0" cellpadding="0" cellspacing="0" >
The problem could be cellspacing and cellpadding but im not sure ... really good tool for this stuff is firebug , inspect element you will see all used styles etc.. or try to fix td height on 50px like your img
I cannot figure out this positioning problem in Firefox. It doesn't seem to follow the absolute positioning rule. Is there something I'm doing that shouldn't be done, but some browesers handle it and some don't?
JS Fiddle:
Original - http://jsfiddle.net/g9qzh/
Updated - http://jsfiddle.net/g9qzh/2/
Works in IE, Chrome, Safari, Opera
Here's the actual code. Let me know if I'm not following some kind of standard I don't know about.
HTML:
<table>
<tr>
<td>
<div id="three">Three</div>
<div id="two">Two</div>
</td>
<tr>
<tr>
<td>
<div id="three">Three</div>
<div id="two">Two</div>
</td>
<tr>
</table>
CSS:
#two {
position: absolute;
top: 0;
}
td {
position: relative;
}
My only clue is that there is some other value that I should assign to td that would cause it to work. Some other stackoverflow questions have mentioned Firefox misbehaving with this, but I haven't been able to find an answer. I tried assigning both top and left values of zero, but FF won't budge.
Change ID's to classes and also displaying it as blocks fixes it:
http://jsfiddle.net/GchWZ/
It is better and more "proper" to user an inner div though as quoted from this stack overflow post: Does Firefox support position: relative on table elements?
<td>
<div style="position:relative">
This will be positioned normally
<div style="position:absolute; top:5px; left:5px;">
This will be positioned at 5,5 relative to the cell
</div>
</div>
</td>
You are using IDs
IDs are unique. Use Classes if you want to reuse a style assignment.
The problem comes from how FF renders tables. If you set your TDs to display:inline-block; it should display correctly.
Try this:
<tr>
<td>
<div id="wrapper">
<div id="three">Three</div>
<div id="two">Two</div>
</div>
</td>
</tr>
<tr>
<td>
<div id="wrapper">
<div id="three">Three</div>
<div id="two">Two</div>
</div>
</td>
</tr>
and for css:
#two {
position: absolute;
top: 0px;
}
#wrapper {
position: relative;
}
Aside from the duplicate ID issue noted by Brandt, assigning positioning to table cells is dodgy at best - I'm surprised it works in any browsers. If you must use a table, wrap the elements you want to position in a div and assign the wrapper div position: relative:
<table>
<tr>
<td>
<div class="wrapper">
<div id="three">Three</div>
<div id="two">Two</div>
</div>
</td>
<tr>
</table>
CSS
#two {
position: absolute;
top: 0;
}
.wrapper {
position: relative;
}
In case you want to position stuff at the top and bottom of a cell, also in Firefox, I made it work doing the following mix of CSS and (unfortunately) jQuery.
Use a wrapper div (div.inner) inside your td which has position=relative style in the td. Inside the wrapper I added 2 divs which are to be positioned at the top and bottom of the cell.
Positioning at the top (class=interval-start) is for free, via CSS positioning.
Positioning the div.interval-end at the bottom is done via script, which adds the styling shown in the picture. With variable td-heights and the wrapper div being 0-height by default, you need a way to tell the element how far it should go to the bottom. The script is as follows:
$("table .inner .interval-end").each(function () {
$(this).css({top: ($(this).parent().parent().height() - 10) + "px"})
}).show()
I initially made the div.interval-end invisible, set the 'top' style, and then made it visible via jQuery show().
Hope this helps anybody trying to achieve the same. Let me know if there are better methods out there, specially if these methods do not require scripting. BTW: I tried setting the height style of the wrapper div.inner, but it messes with the table layout in Firefox.
There are legitimate reasons to use CSS display: table styling. It eliminates issues that display: block and display: inline-block do not address. These reasons occupy an entire chapter of a book on CSS styling so I won't go into them here. That same book also describes the problem of positioning within items with that display type. CSS 2.1 specs simply don't address the issue and Mozilla has chosen a course that ignores attempts to create a positioning context with those elements. CSS-table positioning is well established, mature methodology, and not "dodgy" - it just takes understanding of its limits - just like any other CSS element. For liquid layouts and other layouts where element size is variable or unknown it's indispensable for vertical spacing and positioning.
One suggestion in this thread has been presented - create a div within the "table-cell" element set to position: relative and use that for the positioning context. The other method is to embed another CSS table within that cell and use it to position elements within a grid. The third method is to wrap your CSS table within another item that creates a positioning context.
When I try to use position: relative / position: absolute on a <th> or <td> in Firefox it doesn't seem to work.
Easy and most proper way would be to wrap the contents of the cell in a div and add position:relative to that div.
example:
<td>
<div style="position:relative">
This will be positioned normally
<div style="position:absolute; top:5px; left:5px;">
This will be positioned at 5,5 relative to the cell
</div>
</div>
</td>
That should be no problem. Remember to also set:
display: block;
Since every web browser including Internet Explorer 7, 8 and 9 correctly handle position:relative on a table-display element and only FireFox handles this incorrectly, your best bet is to use a JavaScript shim. You shouldn't have to rearrange your DOM just for one faulty browser. People use JavaScript shims all the time when IE gets something wrong and all the other browsers get it right.
Here is a completely annotated jsfiddle with all the HTML, CSS, and JavaScript explained.
http://jsfiddle.net/mrbinky3000/MfWuV/33/
My jsfiddle example above uses "Responsive Web Design" techniques just to show that it will work with a responsive layout. However, your code doesn't have to be responsive.
Here is the JavaScript below, but it won't make that much sense out of context. Please check out the jsfiddle link above.
$(function() {
// FireFox Shim
// FireFox is the *only* browser that doesn't support position:relative for
// block elements with display set to "table-cell." Use javascript to add
// an inner div to that block and set the width and height via script.
if ($.browser.mozilla) {
// wrap the insides of the "table cell"
$('#test').wrapInner('<div class="ffpad"></div>');
function ffpad() {
var $ffpad = $('.ffpad'),
$parent = $('.ffpad').parent(),
w, h;
// remove any height that we gave ffpad so the browser can adjust size naturally.
$ffpad.height(0);
// Only do stuff if the immediate parent has a display of "table-cell". We do this to
// play nicely with responsive design.
if ($parent.css('display') == 'table-cell') {
// include any padding, border, margin of the parent
h = $parent.outerHeight();
// set the height of our ffpad div
$ffpad.height(h);
}
}
// be nice to fluid / responsive designs
$(window).on('resize', function() {
ffpad();
});
// called only on first page load
ffpad();
}
});
Starting with Firefox 30, you'll be able use position on table components. You can try for yourself with the current nightly build (works as standalone): http://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/latest-trunk/
Test case (http://jsfiddle.net/acbabis/hpWZk/):
<table>
<tbody>
<tr>
<td style="width: 100px; height: 100px; background-color: red; position: relative">
<div style="width: 10px; height: 10px; background-color: green; position: absolute; top: 10px; right: 10px"></div>
</td>
</tr>
</tbody>
<table>
You can continue to follow the developers' discussion of the changes here (the topic is 13 years old): https://bugzilla.mozilla.org/show_bug.cgi?id=63895
Judging by recent release history, this could be available as soon as May 2014. I can barely contain my excitement!
EDIT (6/10/14): Firefox 30 was released today. Soon, table positioning won't be an issue in major desktop browsers
As of Firefox 3.6.13, position: relative/absolute do not seem to work on table elements. This seems to be long standing Firefox behaviour. See the following: http://csscreator.com/node/31771
The CSS Creator link posts the following W3C reference:
The effect of 'position:relative' on table-row-group, table-header-group, table-footer-group, table-row, table-column-group, table-column, table-cell, and table-caption elements is undefined. http://www.w3.org/TR/CSS21/visuren.html#positioning-scheme
Try using display:inline-block it worked for me in Firefox 11 giving me positioning capability within the td/th without destroying the layout of the table. That in conjunction with position:relative on a td/th ought to make things work. Just got it working myself.
I had a table-cell element (which was actually a DIV not a TD)
I replaced
display: table-cell;
position: relative;
left: .5em
(which worked in Chrome) with
display: table-cell;
padding-left: .5em
Of course padding usually is added to width in the box model - but tables always seem to have a mind of their own when it comes to absolute widths - so this will work for some cases.
Adding display:block to the parent element got this working in firefox.
I also had to add top:0px; left:0px; to the parent element for Chrome to work.
IE7, IE8, & IE9 are working as well.
<td style="position:relative; top:0px; left:0px; display:block;">
<table>
// A table of information here.
// Next line is the child element I want to overlay on top of this table
<tr><td style="position:absolute; top:5px; left:100px;">
//child element info
</td></tr>
</table>
</td>
The accepted solution kind of works, but not if you add another column with more content in it than in the other one. If you add height:100% to your tr, td & div then it should work.
<tr style="height:100%">
<td style="height:100%">
<div style="position:relative; height:100%">
This will be positioned normally
<div style="position:absolute; top:5px; left:5px;">
This will be positioned at 5,5 relative to the cell
</div>
</div>
</td>
</tr>
The only problem is that this only fixes the column height problem in FF, not in Chrome and IE. So it's a step closer, but not perfect.
I updated a the fiddle from Jan that wasn't working with the accepted answer to show it working.
http://jsfiddle.net/gvcLoz20/
I have the following code that I am using to display a search tool with a scrolling results section. In IE the code works fine:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<html style="background:black;height:100%;width:100%;">
<head>
<title>Report</title>
</head>
<body style="background:black;">
<table HEIGHT="100%" WIDTH="100%" style="background:red;">
<tr>
<td>
Search Area
</td>
</tr>
<tr>
<td HEIGHT="100%" WIDTH="100%" style="background:orange;">
<div style="overflow-y:scroll;height:100%;">
<table style="width:100px;height:1000px;">
<tr>
<td style="background:white;">
Results Area
</td>
</tr>
</table>
</div>
</td>
</tr>
</table>
</body>
</html>
But when I set the meta tag to use IE8 formatting by adding:
<meta http-equiv='X-UA-Compatible' content='IE=edge' />
The bottom DIV tag expands beyond the page. I have tried a number of options though and can't find a way around it without actually specifying a height for the values. Which will not work as I want the page to take up 100% of the screen no matter the size of the browser window.
Any help would be much appreciated.
This metatag enables correct CSS rendering, and in CSS – by design – height:100% basically doesn't work.
You need to give specific height to every single ancestor of the element, including <body>, <table>, <tr> and even <tbody> element that's automatically inserted by the parser.
Anyway, this layout can be achieved in easier way:
.topBanner {
position:absolute; position:fixed;
height:2em;
top:0; left:0; width:100%;
}
body {padding-top: 2em}
this will degrade nicely in IE6, and unlike overflow, will work properly in Mobile Safari.
Edit:
Removing the DOCTYPE declaration will make height="100%" work but it puts the browser in quirks mode though, which is not desirable.
Generally speaking using tables for layout is discouraged, you should use CSS instead.
For example: http://jsfiddle.net/rf649/7/
HTML
<div id="search">Search Area</div>
<div id="results">Results Area</div>
CSS:
#search {
background-color: red;
position: fixed;
height: 150px;
width: 100%;
}
#results{
background-color: orange;
position: fixed;
top: 150px;
width: 100%;
bottom: 0;
overflow: auto;
}
You should set all margins and paddings for the parent elements to zero in order to get what you want.
Update: Sorry, didn't understand the problem at once. Ben's hint should be the better one I assume. :)
Update 2: Oops, since Ben has deleted his answer my first update doesn't make any sense. Try setting the body's height to 100%, that should solve the problem.
My understanding about cross browser CSS is not that big so it might not be the best solution, but it's a solution.
As far as I've seen, you always have to set the height/width of the container that you want to overflow, so you need to set them.
To deal with the resolution I would suggest you to add a jQuery script at the onReady event that dynamically would fix the height and width making the overflow work.
I had the similar problem like you and finally the solution was to modificate a CSS line entry that had an !important modificator for a fixed height declaration. In the HTML code the class (defined in CSS) had the height assigned to 100%, but the CSS applied the !important during the style loading.
