Critique, image slicing for fluid CSS layout tutorial

am 08.11.2007 05:44:40 von Nik Coughlin

I am halfway through writing a tutorial on image slicing for fluid CSS
layouts, I would love some feedback on what I've done up until this point:

http://nrkn.com/index.html

I am still writing parts 3 & 4, "optimising the layout" and "alpha
transparency".

Also, does anyone know why I don't get numbers or bullets on my ul and ol in
Internet Explorer (6 or 7)?

Thanks!

Nik,

Whatever the explanations are for the semi-disappeared (or entirely
disappeared) list markers in Internet Explorer 7, I truly and
completely believe that you should avoid this kind of markup code:

Line 30:



Line 34:



Line 81:



Line 89:

Remember/keep in mind that the original purpose and goal of using CSS
was to reduce resorting/recourse of bloated markup code: if your CSS
code does not achieve that, then you should examine how you could
reduce the depth and the width of the DOM tree of nodes.

Hi Gérard!

It's not divitis, believe it or not.

It is totally necessary to create the fluid effect. Have a look at
http://nrkn.com/basic.html#markUp for an explanation of what those are
doing.

You *can't* do this otherwise. Seriously :) With CSS 3 you can assign
multiple backgrounds to one element, but there's no support for it yet, so
for now you have to nest multiple elements in order to do this. I use a
series of nested divs as div is semantically neutral.

> Line 30:

These are also necessary. They're spacers that stop the content of the page
going where it shouldn't (because of the curved shape of the top part of the
design).

> Line 34:


> Line 81:



Again, necessary for that graphical effect, having the horizontal divider
shrink and grow to the width of the viewport. Same principle as above.

Yep, totally agree, but this ain't it :)

I believe that this is the minimum amount of markup necessary to achieve
this effect :) Would love to be proven wrong.

Hello again,

You first declared

ol {font-weight: bold;}

in

ol {
color: #5ac90f;
font-weight: bold;
margin: 1em;
}

and ol span {font-weight: normal;}

ol span {
color: #b95207;
font-weight: normal;
}

(Notice here that you re-declare the color for the span instead of
using inheritance. All you had to do is declare color: #b95207 for the
ol element and that was it!)

then used on 3 chunks of text (only 6 words)

and then declared 7 with font-weight: normal;.

When debugging your code, I removed all that. Everything. And just let
the 3 semantic for the 3 chunks of text (a grand total of 6
words). I removed 7 non-semantic , removed both font-weight
declarations, remove 1 color declaration and replace the remaing one
with #b95207, then removed the ol span CSS rule.

Your CSS code is definitevly improvable, optimizable.

Also, this universal selector rule
* {
margin: 0;
padding: 0;
}
is a clear sign of over-declaring, over-defining. The use of the
universal selector is very rarely recommendable and is discouraged by
many CSS gurus.
By removing all margin and padding on all elements, you are later
force to add them back almost everywhere (for almost all elements like
p, li, headings, etc) instead of relying on browser default
declarations. I personally never do that and I certainly do not
encourage that practice because it invariably lead to over-declaring,
over-defining.

Finally, regarding your question of disappearing list markers in MSIE
7, you need to increase the margin on the ol to at least 1.5em. I have
created a reduced testcase showing this phenomenon, where the list
markers disappear at around margin: 1.1em. IE has a particular way of
displaying list markers..

Regards and good luck,

G=E9rard

Is the effect worth the internal complexity?
Maybe it would be better to just spend more time in the Gimp
perfecting normal images, keeping the page itself simple.

Forcing markup like this:



is just unsemantic, even though it is technically valid.

You're right, I'm not quite sure why I did that :)

Actually, the reason for declaring a color for the ol and then wrapping the
li content in a span is so that that the list markers have a different
colour to the list items. There *is* method to the madness! Some would say
that it's not worth having to have the extra markup just to have different
coloured markers, but I think it makes quite a big difference visually, so I
am willing to make that sacrifice.

Yeah, the font-weight thing is a cock-up.

Yep, there are some rules that can be combined that I can see right off the
bat. Anything else off the top of your head that you've noticed is
particularly in need of improvement, or do you just mean combining rules
that are repeated?

We will have to agree to disagree on this :) I like this a lot as it
equalizes the way browsers set margins and padding, which are different
between different browsers for different elements.

I find with the layouts that I tend to do it's the opposite, I am always
turning margin and paddings *off* on multiple elements, and with the
universal selector I only end up turning them back on in a few places.

Excellent, thank you very, very much!

Thanks again. I really appreciate you taking your time to discuss this with
me. It has been a pleasure, even if we disagree on some things!

No amount of time spent in the Gimp will help me make an image that
stretches to fit the available width though!

Well, for me, sometimes there are trade offs between getting a visual
effect, and being semantically correct. The extra div wrappers are to get
the visual effect (divider that fades away at the edges and resizes to fit
the available width), the
is there so that there is still a horizontal
rule when CSS isn't present.

Some of these things are just necessary to address the shortcomings of
browser support for HTML/CSS -- almost all of these shortcomings are
addressed in CSS3. If IE/Opera/FF supported multiple background images on a
single element (Safari does) then it wouldn't be necessary.

How I wish it were so!

Thanks for your time :)

Depends on how you count it. It only has to be done once by the
author, and from then on it can give multiple pleasure. On
principle, this may well be worth it.

This is yet another issue. But, given that there are limitations
in browser implementations of some css where this sort of thing
can be more easily done in a kosher manner, it is very severe to
never fall to temptation. Perhaps it is an area where a little
individual choice might be allowable.

I hope so :) I try to only compromise on these things when a visual effect
that I want is otherwise unattainable. Oh, for multi-browser support of
CSS3!

Indeed, tell you what though: I would at this moment settle for
multi-browser support of CSS 2.1

I'll have to trust others reports that it gives them pleasure.

Like the often seen attempts at rounded box corners, it looks
mid-90s kitschy to me, but as you say below, individual choice might
be allowable.

One has to abstract from the individual implementations. The
argument might be on a higher level, namely, are all designs that
stretch and bend and flex various things that cannot be so easily
done 'purely', to be ruled out of order on grounds of a semantic
ideal, is semantic purity in web matters such a very strong and
clear concept that it can bear the weight of such strictness?

So weighty and poignant are these questions that I urge a
humbleness before them, a patience from rushing to judgement.

Despite your rationalization, the least css is the best css. I believe
GTalbot has already resolved the original issue, but Nik is no dummy so the
real problem is the complexity of the styling.

Being later forced to add spacing back to elements is one of the reasons
Eric Meyer *likes* it (see his "Reset Reloaded" article at
with some
more of the reasoning behind it at
),
although he does specifically say he doesn't like the * universal
selector, he does do this:

html, body, div, span, applet, object, iframe,
h1, h2, h3, h4, h5, h6, p, blockquote, pre,
a, abbr, acronym, address, big, cite, code,
del, dfn, em, font, img, ins, kbd, q, s, samp,
small, strike, strong, sub, sup, tt, var,
dl, dt, dd, ol, ul, li, fieldset, form, label, legend,
table, caption, tbody, tfoot, thead, tr, th, td {
margin: 0;
padding: 0;
etc.

While I see his reasoning, I'm not yet persuaded I want to do this for
every page/site I do. But then, I'm not a CSS guru, so maybe my lack of
experience keeps me unenlightened. So like you, Gérard, I never do it
either.

Other discussions of the "reset all" philosophy can be found via an
article called "CSS Frameworks + CSS Reset: Design From Scratch" at

, although that page is best visited with CSS (and JS) turned off.
Ironically enough, with CSS enabled, the page takes forever to load and
respond to scrolling. (Disabling JS just keeps the ad count down.)

Nice tutorial, I like the layered header idea. Of course you make the
assumption that the header graphic has something on the right and
left, but the middle can be expanded. But when the header can be
handled like that, this is a nice plan.

So what? Who says HTML should be entirely semantic.

CSS is _very_ simple and deliberately (read Hakon Lie's PhD thesis)
doesn't include some of the features of other styling langauges.
Amongst these is the ability to do powerful content generation,
sufficient to generate the necessary "hooks" to hang each necesary box
of the rendering model onto. This is particularly evident when
clearing after a sequence of floated boxes.

Some stylesheet languages do support this, but they're more complex
than CSS. CSS gains its simplicity here by requiring the HTML to
already contain a sufficiency of "hook" elements that deliberately
have no smenatic purpose, they're only used (and necessary for)
presentation.

It would be nice to have a purely presentation-free HTML, but not at
the cost of needing to use DSSSL to style it!

I see a kind of smooth scale from pure semantic markup to
clog dancing monkeys. Different people place different points along that
scale where you should just control yourself, or switch over
to Flash or Java Applets. I would resist using the kind of code here
because I would not want to maintain it, and I just find its appearance
unneeded aesthetically. Of course you have to occasionally give in
to clients. (This is also my answer to Andy's reply.)

I would love to expand it to include other scenarios in mind, can you think
of any examples? Thanks!

You have to abstract from particular cases. In plain terms, this
means that you cannot know in advance that it is not worth an
author's time for any site at all. Perhaps we need more examples
of the actual use of code that gets tut tuts from some but which
are plainly nice in effect and hard or impossible to do without.

The fair and substantial complaints are for sites that

(1) Look bloody awful anyway

(2) Work badly in other respects, partly as a result of an
authors over attention to the fancy at the expense of the very
important and unarguable criteria like decent font sizes, screen
flexibility and so on. (Lemme point out that the effect of the
OP's interesting attempts is to at least avoid the often unwanted
fixed nature of images when they are for decoration, this is a
positive for fluid construction).

About maintenance, there are several issues. If an author is in
command of what he has done then it may be very easy for *him* to
maintain it. As for the business of others taking over the site
to maintain it, a sense of perspective is needed. Many of these
fancy things can be commented by the author so the next person
can understand, the commentary might even explain how to dispense
with the fancy parts altogether. Then it is the choice of the new
person (if he has the authority).

What do you mean by "appearance" ? Appearance as finally rendered on
the page, or appearance of the source code, as a rather specialised
aesthetic view by a code guru?

As simple example, you can code "a picture gallery of blocks" as
either a

or as floated
s. When rendered, the floated
s are considered "better", as they give a more flexible and fluid
rendering. Looking inside the source though, there's a problem in how
to achieve this: it _does_ require more coding. It requires more CSS
and more HTML. In particular, there's a trade-off in how you clear-
down after a sequence of floats. This can be (sometimes) done by
complex and non-robust work in CSS selectors, or more simply and
reliably overall by adding a sprinkling of extra (but justifiable)
HTML elements.

So which do you prefer? I'm not a great fan of additional HTML
elements to clear up after floats, but how else are you going to do
it? De-evolve the design back to a
? Use tricksy CSS that
really is hard to understand? Sloppy work with a ragged bottom edge?
Or do it simply, cleanly and correctly, even if it's a little more
verbose? I know which I prefer.

"Divitis" is a hard condition to diagnose, and it's prone to excess
mis-diagnosis. The number of HTML elements should (as a general
principle) be kept to the minimum that are useful, but not reduced any
further!
