So my company now has a private internal blog. Which is pretty random, 
really. But the thing that gets me is that it's so much more *pretty* 
than my blog. I mean, it looks really slick. Take a look at the 
attachment. I would imagine it's a default theme or something for 
whatever off-the-shelf blogging engine they're using. But damn, how do 
you draw something this nice in the first place? And once you've drawn 
it, how the hell do you make it into a web page?

That's not going to tell me how the graphics were drawn, is it? :-P

If I'm lucky, I might be able to determine how this elaborate collection 
of images was stiched together to make a web page. But in all 
likelihood, the CSS and stuff was machine-generated and will be utterly 
unreadable.

Funny thing is, I've figured out how to do this with a graphics card, but I 
still am not sure if it would work the same for a HTML page. :-)

I didn't particularly note any graphics, unless you were referring to the 
page layout.

In which case, you might look at Inkscape, since ISTR it has the ability 
to export vector drawings to be used as a web layout.

That's quite possible.

Me neither, which is why I let a web design professional do the heavy

Oh, sweet! Now when you do "view source" in Firefox, anything that's a 
link is actually hyperlinked. That's nice.

OK, so looking at the CSS for this page, apparently it's a WordPress 
theme called "black piano":

I fondly remember the first company I ever worked at where people weren't 
pissy and selfish and grumpy. I had hand-drawn a diagram of a rather complex 
architecture, with multiple messages flying between computers in different 
administrative domains and stuff like that.  I went to the head of marketing 
and said "Do we have anything I could use to turn this into something 
presentation-quality?"  She took it from my hand, glanced at it, reached it 
over the wall of the cubicle she was standing next to,and said "Yes. His

OK, they's nothing jaw-droppingly "wow" about it. It just looks really 
sharp and stylish. And I can't put my finger on why. (Which is probably 
part of why I can't replicate it...)

Uh, yeah, that's affirmative. I took Black Piano apart and discovered 
that it doesn't work the way I thought it did at all! Somehow it manages 
to layer semitransparent images ON TOP OF EACH OTHER. It's news to me 
that this is possible. This changes everything...

Now, if I can just figure out how this works... (The code is a tangle of 
CSS and JavaScript events, and there are property names in there that 
I've never even heard of.)

I've been using Artisteer for a while now. It's a (commercial) theme 
generator for a variety of popular CMS. It's really a useful program it you 
need a nice-looking website and don't have the time to learn how theming is 
done in the CMS you're using. I've been using it for Joomla and Drupal but 
it does Wordpress too. It does not replace a true web designer, but it's 
faster than endlessly tweaking the CSS of existing themes.

Why would you need scripting for that?

Mmm, interesting. Of course, since I won't be using a CMS, I'm not sure 
it helps, but it's interesting to know that such things exist.

I think my basic problem is that I'm not a graphic designer. When I look 
at a blank screen, I can't imagine what I might put onto it that would 
look cool...

Actually it's part of the various bitmaps.

If you look at the theme demo (not my cut up image), you'll see that the 
top of the page has a subtle blue glow to it.

The way it works is rather surprising.

There's a 5x5 pixel image that consists of grey with a black stripe 
across it. This is tiled to form the stripey background.

There is an image named "top". This is the black slab with the rounded 
corners and the drop shadow. The bit that the page title appears on top of.

Yes, that's right. Somehow they put text ON TOP OF an image. Not only 
that, but somehow they put one image ON TOP OF another image, WITH 
TRANSPARENCY. I have no idea how that's possible.

There's also an image that's blue in the center, and fades to 
transparent towards the edges. This is somehow displayed ON TOP OF the 
background image to generate the blue glow at the top of the page.

Then there's an image that's 2 pixels tall, just consisting of various 
shades of grey. This is what generates the two-tone grey for the body 
text and the sidebar. But it's TRANSPARENT, showing the stripe texture 
through from below. (And also the blue glow.) And it has a drop shadow 
at each end, which also blends through.

Finally, there's a "bottom" image, which implements the semicircular 
bottom of the page. (You can just about make out where the edge of the 
sidebar doesn't line up perfectly.)

In a similar way, there are a pair of "top" and "bottom" images 
containing a black bar with a curved end; this is what implements the 
black markers at the bottom of each post, where it tells you the number 
of comments, etc. (This also explains why the curve isn't quite right. 
You can also see a glitch in the dotted line where the two halves of the 
image meet.)



Last time I checked, there are two ways to put an image into a web page. 
You can use the IMG tag, which inserts an image in amoungst the text. 
(But you cannot put anything over the top of this image.) Alternatively, 
you can set the page background image, which is obviously behind 
*everything*. That means you can put things over the top of it.

That gives you two ways to build a page like this:

1. Draw the entire page, with all the borders and lines you want, and 
then use CSS to position the text into the spaces in the graphic. (This 
means the page must be a fixed size, since the background graphics have 
been drawn at a fixed size.)

2. Draw the entire page, and chop it into pieces. Use IMG tags to insert 
each piece of the frame around the outside of the text, keeping the text 
inside the frames. If you want the text itself to have a background, 
things get tricky. But by using a repeating pattern, you might be able 
to make the page semi-resizable.

This theme uses neither approach. Somehow it manages to combine multiple 
layers of semitransparent images *at the client end* to produce the 
final page. I have still to discover how that's possible. (Not to 
mention how the hell you line all the text up nicely...) The fact that 
the CSS code is litered with properties I've never even heard of is 
probably the first clue. Unfortunately, it's not very readable in there...

(I have to find out what tags and classes exist in the HTML and what 
they contain, then see where they end up on the rendered page, and then 
see what CSS is applied to them, and lookup what images are being 
referenced, and then see the JavaScript that's manipulating them, and...)

Out of curiosity, how does one "learn" Photoshop anyway?

Presumably it doesn't come with a manual - or if it does, it only covers 
what each button and menu item does (which isn't the same as knowing how 
to *use* these tools to achieve a particular goal).

Also, Photoshop costs something absurd like £700, which normal humans 
don't have.

You have to use CSS. There is a css-property called z-index, allowing you to 
stack elements that have this property. There are "left", "right", "top", 
"bottom" properties, allowing you to position elements with pixel-precision: 
add style="position: absolute; left: 10px ; top: 10px; z-index: 2;" and 
style="position: absolute; left: 20px; top: 20px; z-index: 3;" to a 
div-element containg pictures and see what happens.

Note the "position" properties. They are important - read up on them.

Then you have a several css-properties for background: you can layer 
div-elements one upon the other, and overlap them using "left", "top", 
etc. - and each div-element can have a seperate background. The background 
for each and every element can be aligned ("background-align" property) and 
you can decide whether you want to repeat it or not. So you can position an 
image within a div-element and have a backgound for this element. If the 
background is a transparent image, the images and text below will show 
through. Or, with IE, there are things called filters - neat things can be 
done with them - but they are something only supported by IE, so best keep 
away from them).

There are pitfalls, though. Not every browser supports css properly and you 
have to make sure the browser is in the right mode. Mode is set by 
HTML-DOCTYPE, I'd advise

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" 
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

It can be very hard to debug a style. Firefox with the Firebug-Extension is 
your friend.

If you really want to dig into this, you have to learn how css works. And 
how to circumnavigate the various browser-bugs.

For a background that goes from one colour to another you can use your 
paint-program, create a line with fill-properties starting at blue and 
ending at white. Then put this 1-pixel line in the background property of 
your [whatever div or document part you want it to be]. Set style= 
"background-repeat: none; background-position: top; background-align: left;" 
and you have got what you want. Of course there are pitfalls here, too.

To explain all this properly is like asking somebody how to do a macro with 
sphere-sweep in povray - and why it sometimes gives rather unexpected 
results and in which cases it does and what to use as remedy. Or lecture on 
the finer points of photons in povray. Not easy, for obvious reasons.

  You use it. You read tutorials on the internet (do you really think there

Yeah, one way is to use IMG tags in the HTML, the other way is the 
background property in CSS.

Besides, ideally your HTML should contain *only* the text you're trying 
to display, and CSS should do all the styling. A while back I found this:

http://www.csszengarden.com/

Just by changing the CSS, it completely rearranges the entire contents 
of the page. And I thought CSS was just for changing colours...

Yeah, I remember reading about that. I didn't think any known browser 
supported it though?

Oh, mind you, I guess that was a while ago...

Yeah, I've played with them, but I could never think of any useful 
purpose for them.

Yeah, you can set the position relative to the rest of the flow, or 
absolute relative to the page, or relative to the browser frame, or...

Now, see, I was under the impression that setting a background 
completely overrides any previous setting. And yet here we have a page 
with a stipey background, and then a glow background on top of that. Or 
DIV boxes with a transparent background so what's below shows through 
(rather than being replaced).

Sure, you need to avoid quirks mode and stuff, and as soon as you use 
CSS it's 100% guaranteed that it will only ever work in the one version 
of the one browser you tested with. I get that.

> It can be very hard to debug a style.

Hell yeah. Almost as hard as trying to debug JavaScript...

> If you really want to dig into this, you have to learn how css works.

I already know how CSS works. What I seem to be missing is that since I 
last looked at it, they've added some new features.

Sure. I get that. (Although I don't possess a "paint program" to create 
this image with in the first place... I'd have to write a custom program 
to generate the pixels and write them to file, which is a little tedious.)

In my experience, most Internet tutorials aren't very useful. (Although 
there are always exceptions.) And since povray.off-topic is the only 
"colleagues" I have, asking here is only going to give me "dude, GIYF!" 
Books are similarly hit-and-miss, but I'm sure there's some good ones 
out there. The tricky part is finding them. ;-)

  That's because you don't try them. When you read a tutorial you have to
actually *do* what the tutorial is saying, step by step. Just reading it
is not enough. You learn by doing.

If the tutorial doesn't make sense, it's not a good tutorial.

If the tutorial doesn't explain the part I'm trying to learn, it's not a 
good tutorial.

Most tutorials I've seen fall into one or other of these categories. (As 
I say, there are always exceptions...)

That has been possible since forever. Except in IE which didn't support 
alpha channel on PNGs.

You can put an image as a background on ANY element.

<div style="background-image: url(foo.png)">hello <img src="bar.png"></div>

If you don't use any paint program yet, try the GIMP. It is free, can do 
much, and is available for almost any OS I know.

www.gimp.org

It is not my first choice because I do not like the interface. Since you 
don't use a paint program yet, this will be no problem. The GIMP should come 
in handy when post-processing povray images, too. ;-)

With the right plugins GIMP can do many interesting things to a picture... 
so sometimes I use it in spite of the interface. ;-)

If you want vector-images then inkscape looks promising. Not yet commercial 
grade stuff, mainly because it has not many export formats, but it is free 
and it imports PDF nicely. I think this is a program to watch.

BTW: if you want a >really< interesting background, then use an animated gif 
(but keep down the loops to a few, else the text becomes unreadable)

  If he is unwilling to learn to use a program like Photoshop, I doubt he
will be willing to learn to use the Gimp.

  Uh, what?

Seconded. The game programming tutorials I was reading often had bugs in 
them - stuff that basically wouldn't compile, due to sloppily changing one 
part but not the other, for example.  Figuring out what was broken was very 
informative.

It's still an img tag. You just need to use CSS on it.

Heh. That drawing book had great reviews, and yet still it didn't really

I'm unwilling to learn Photoshop because I don't *have* Photoshop! :-P 
Learning how to use something I haven't got isn't going to help me very 
much...

Well, understand that I learned about HTML, XML, CSS, etc. waaay back in 
2001. Sure, I occasionally go read the latest W3C draft from time to 
time, but I haven't done a huge amount of this stuff recently.

I just got home, clicked it to remind myself what it looks like, and 
GAH! >_< Did I really waste 2 hours making this? It's awful! :-S

Must try harder...

(Still, just making the vertical colour gradiant is painful when you 
have to type in all the RGB values by hand, trying to guess what might 
look nice.)

Well, there is that too, yes. ;-) From what little research I've done, 
the way the GIMP works makes sense to the people who designed it, but 
fails to follow any normal kind of intuition, making it maddeningly hard 
to learn.

I've seen it, I've used it, it's nice that it exists, but it's really 
not very easy to do anything remotely useful with it.

That's what the plethora of third party books covers.

There are other graphics programs besides Photoshop - like the Gimp.
