/********************************************************************************
To adjust the side col widths, or the vertical col dividers, a certain set of values must be changed
all at the same time and by exact amounts or problems will result. Each of these group's member values
have been marked off with comments that start with "Critical...". For example, if the left col width needs
to be changed then all the values marked "Critical left col dimension value" MUST have their pixel values
altered by the same amount. Certain of these left col width values are marked "(moves inversly)", and
these get changed by the same pixel amount but inversly to the other values. So if margin-left on .outer
is increased by 10px, then the width of .outer must decrease by 10px, and so on.
To change the width of the entire layout, .wrapper, .outer, .float-wrap, and .center all get changed together,
and only after that is it safe to change col or divider widths. Remember, even one small mistake will degrade or
even break the layout, so be very careful! it's possible to "loosen" the layout so small errors aren't so messy,
but then it becomes hard to finely control text spacing.
For spacing within the cols, it's best to apply margins on content elements inserted into the cols,
because padding directly on those col elements will change their widths, breaking the layout.
Certain hiding hacks have been used extensively in this layout, so here is a quick explaination of them.
The Tan hack:
* html .anyelement {rules read only by IE/Win and IE/Mac}
The Mac-hack: (first the active comment you are reading now must be closed...) */
/* \*/
/* */
/*...Back in comment mode now. Anything between those two comment lines will be hidden from
IE/Mac. Don't use any comments within this hack or it will close prematurely and IE/Mac will begin
reading before it should.
The above two hacks are combined so as to feed rules only to IE/Win. Proper use of backslash escape
characters inside property names used in the Holly hack can further segregate rules to be read by only
IE6 from rules for IE5.x/Win.
These hiding hacks, along with several other fixes, make possible this formerly impossible layout.
It is highly unlikely that new browsers will have any problem with these valid hiding hacks, and
Microsoft does not plan any browser changes soon that would alter the proper operation of the layout.

to see the "height: 1%" to give it some kind of box dimension. Browser coddling
we call it. Finally, Bruno found that "word-wrap: break-word;" disarranged the
justified text in IE5.5 and 6, so it is defaulted to "normal" for this text.

<h2>First in source</h2>
<p style="font-weight: normal; margin: 10px;border: 1px solid #900; background: white; padding: 15px;">
<strong>Important new information as of July 2008: </strong>
IE bugs discussed in this obsolete document have been found to be associated with
<a href="http://www.satzansatz.de/cssd/onhavinglayout.html"><strong>hasLayout</strong></a>.
Knowledge of this MS concept is essential if you want to make IE behave well
with advanced CSS using floats.
Also see this <a href="articles/haslayout.html"><strong>basic method</strong></a> for specific ways to
combat the IE bugs on your pages.
</p>
<p>
This column is first in the source, being a right float within a left-floated wrapper. The second col
is floated left in that same wrapper, and following the wrapper is the left floated right col. (confusing, ain't it?)
</p>
<p>
The headings and italicized paragraphs are "widthless" and have 1px red borders to show any width problems
in the columns.
</p>
<h3>Some Of The Features</h3>
<img src="images/beach.jpg" style="float: right; margin: 10px 0 8px 20px; display: inline; width: 301px; height: 405px;"
alt="This image demonstrates how floated items are no problem in the layout"
title="This image demonstrates how floated items are no problem in the layout" />
<p>
Any col may be longest without problems, thanks to the fact that all the cols are
floated and "within" a single container. The notorious problems that IE has with
floats are negated because all the cols are floats, leaving no normal elements to
interact with them and induce IE bugs. Woohoo!
</p>
<p>
A number of bug fixes have been used to make this design work well in different browsers,
particularly IE/Win. Most of these can be applied in the stylesheet and forgotten, but several
involve tiny dimensional differences and need to be changed when alterations are desired
for the layout. Detailed instructions on this subject are to be found in the source stylesheet.
</p>
<p class="italics-test">
Italics can be used in this design, but when text is "justified" as well, it seems to make IE pre-calculate
box widths and then calculate the width of the italics after that, forcing the box bigger than the stated
width. In a float layout like this, such stupidity leads to display flaws and even destructive float dropping,
so if these two properties are used in the same paragraph a couple of precautions must be used to avoid
IE text buggery.
</p>
<p class="italics-test">
First, using the Holly hack to exclude all but IE/Win, apply to the paragraph a fairly large negative right margin.
The value can be too small, but apparently can never be too big to cause harm. This layout uses -30px right margin.
Then pixel size the width of the paragraph or other element to the widest width you can without float
dropping at the largest text size in IE. You can determine this width by trial and error in a few minutes.
Study the source to see exactly how it's done.
Remember, if both text properties are used on even <em>one word</em> it may cause trouble unless the fix is used.
</p>
<h3>Piefecta's Dirty Little Secret</h3>
<p>
This design employs a proprietary IE property that forces a spaceless url or word to break
before it cause IE to enlarge the floated box and break the layout. If the CSS must validate,
place the "word-wrap" rule in a "conditional comment" (as in this demo). It's also proprietary, but validatible.
</p>
<p>
Note for IE5/Win: This fix fails in IE5/Win, alas. Also note that use of "word-wrap" in conjunction with justified
text prevents IE5.5 and 6 from lining up the text on the right edge. That property has been set to "normal"
in the italics test boxes to keep the text justified on the right.
</p>
<h3>Update July 4th, 2008</h3>
<p>
The W3C has decided to adopt the <strong>word-wrap</strong> CSS property into the CSS&nbsp;3 specification.
(the W3C was going to change MS's syntax at first, but someone gave them all "dope-slaps" and they
came to their senses, thankfully) Word-wrap is already supported by <strong>Safari&nbsp;3/Win</strong>,
<strong>Opera&nbsp;9</strong>, and of course <strong>IE</strong>. Only <strong>Firefox&nbsp;3</strong>
does not yet support this vital CSS tool. C'mon guys, get with it!
</p>
<p>
Since the W3C has endorsed word-wrap, we are free to use it, even tho it may not
pass the validator for a while.

Mucho thanks to
<a href="http://www.neuance.net/"><strong>Douglas&nbsp;Livingstone</strong></a>,
who developed the brilliant
<a href="http://www.redmelon.net/tstme/3cols2/"><strong>Negative&nbsp;margined&nbsp;floats</strong></a>
method at the heart of this design. Thanks, Douglas! Next step is to add a "sticky&nbsp;footer" as shown by
<a href="http://www.pmob.co.uk/temp/3colfixedtest_sourcenone.htm">Paul&nbsp;O'Brian</a>.
</p>
<p style="margin-right: 152px;">
The Master of the Mac, <a href="http://www.l-c-n.com/IE5tests/">Philippe&nbsp;Wittenbergh</a>,
came thru with crucial Mac fixes, as usual, along with
<a href="http://www.sperling.com/">Tedd&nbsp;Sperling</a> on cleanup detail.
<a href="http://65.109.140.59/">Bruno&nbsp;Fassino's</a> work on the text fixes for IE
came along at just the right time. This layout is
truly the result of the efforts of many coders over a long period. Thanks people.
</p>
<h3><em style="color: #c00; font-size: 1.2em; font-family: Verdana, sans-serif;">Special Announcement!</em></h3>
<p>
Now, thanks to the hard work of Trevor, aka 'ClevaTreva', you may easily have a
<a style="color: #228;" href="articles/pie-maker/pagemaker_2_9_home.html">coded version of the Piefecta
layout prepared for you, <em>automagically!</em></a>&nbsp; This unsung script/css genius has crunched the
incredibly complex rules of this design down into a tool so cool that all primary layout mods are
a "no-brainer". Woohoo!

Tweaking the cols can be very confusing due the interlocked nature of the layout, but colored backgrounds
