/*

So you like the style of impress.js demo?
|
||||||
|
Or maybe you are just curious how it was done?
|
||||||
|
|
||||||
|
You couldn't find a better place to find out!
|
||||||
|
|
||||||
|
Welcome to the stylesheet impress.js demo presentation.
|
||||||
|
|
||||||
|
Please remember that it is not meant to be a part of impress.js and is
|
||||||
|
not required by impress.js.
|
||||||
|
I expect that anyone creating a presentation for impress.js would create
|
||||||
|
their own set of styles.
|
||||||
|
|
||||||
|
But feel free to read through it and learn how to get the most of what
|
||||||
|
impress.js provides.
|
||||||
|
|
||||||
|
And let me be your guide.
|
||||||
|
|
||||||
|
Shall we begin?

That's the one by Eric Meyer http://meyerweb.com/eric/tools/css/reset/

You can probably argue if it is needed here, or not, but for sure it
|
||||||

doesn't do any harm and gives us a fresh start.

Now, when we have all the steps styled let's give users a hint how to navigate
|
||||||
|
around the presentation.
|
||||||
|
|
||||||
|
The best way to do this would be to use JavaScript, show a delayed hint for a
|
||||||
|
first time users, then hide it and store a status in cookie or localStorage...
|
||||||
|
|
||||||
|
But I wanted to have some CSS fun and avoid additional scripting...
|
||||||
|
|
||||||
|
Let me explain it first, so maybe the transition magic will be more readable
|
||||||
|
when you read the code.
|
||||||
|
|
||||||
|
First of all I wanted the hint to appear only when user is idle for a while.
|
||||||
|
You can't detect the 'idle' state in CSS, but I delayed a appearing of the
|
||||||
|
hint by 5s using transition-delay.
|
||||||
|
|
||||||
|
You also can't detect in CSS if the user is a first-time visitor, so I had to
|
||||||
|
make an assumption that I'll only show the hint on the first step. And when
|
||||||
|
the step is changed hide the hint, because I can assume that user already
|
||||||
|
knows how to navigate.
|
||||||
|
|
||||||
|
To summarize it - hint is shown when the user is on the first step for longer
|
||||||
|
than 5 seconds.
|
||||||
|
|
||||||
|
The other problem I had was caused by the fact that I wanted the hint to fade
|
||||||
|
in and out. It can be easily achieved by transitioning the opacity property.
|
||||||
|
But that also meant that the hint was always on the screen, even if totally
|
||||||
|
transparent. It covered part of the screen and you couldn't correctly clicked
|
||||||
|
through it.
|
||||||
|
Unfortunately you cannot transition between display `block` and `none` in pure
|
||||||
|
CSS, so I needed a way to not only fade out the hint but also move it out of
|
||||||
|
the screen.
|
||||||
|
|
||||||
|
I solved this problem by positioning the hint below the bottom of the screen
|
||||||
|
with CSS transform and moving it up to show it. But I also didn't want this move
|
||||||
|
to be visible. I wanted the hint only to fade in and out visually, so I delayed
|
||||||
|
the fade in transition, so it starts when the hint is already in its correct
|
||||||
|
position on the screen.
|
||||||
|
|
||||||
|
I know, it sounds complicated ... maybe it would be easier with the code?

And as the last thing there is a workaround for quite strange bug.
|
||||||
|
It happens a lot in Chrome. I don't remember if I've seen it in Firefox.
|
||||||
|
|
||||||
|
Sometimes the element positioned in 3D (especially when it's moved back
|
||||||
|
along Z axis) is not clickable, because it falls 'behind' the <body>
|
||||||
|
element.
|
||||||
|
|
||||||
|
To prevent this, I decided to make <body> non clickable by setting
|
||||||
|
pointer-events property to `none` value.
|
||||||
|
Value if this property is inherited, so to make everything else clickable
|
||||||
|
I bring it back on the #impress element.
|
||||||
|
|
||||||
|
If you want to know more about `pointer-events` here are some docs:
|
||||||
|
https://developer.mozilla.org/en/CSS/pointer-events
|
||||||
|
|
||||||
|
There is one very important thing to notice about this workaround - it makes
|
||||||
|
everything 'unclickable' except what's in #impress element.
|
||||||
|
|
||||||
|
So use it wisely ... or don't use at all.
|
||||||
|
*/

/*
|
||||||
|
There is one funny thing I just realized.
|
||||||
|
|
||||||
|
Thanks to this workaround above everything except #impress element is invisible
|
||||||
|
for click events. That means that the hint element is also not clickable.
|
||||||
|
So basically all of this transforms and delayed transitions trickery was probably
|
||||||
|
not needed at all...
|
||||||
|
|
||||||
|
But it was fun to learn about it, wasn't it?

Last, but not least.
|

|
|

|
To make all described above really work, you need to include impress.js in the page.
|
||||||
|
I strongly encourage to minify it first.
|
||||||
|
|
||||||
|
In here I just include full source of the script to make it more readable.
|
||||||
|
|
||||||
|
You also need to call a `impress().init()` function to initialize impress.js presentation.
|
||||||
|
And you should do it in the end of your document. Not only because it's a good practice, but also
|
||||||
|
because it should be done when the whole document is ready.
|
||||||
|
Of course you can wrap it in any kind of "DOM ready" event, but I was too lazy to do so ;)
|
||||||
|
|
||||||
|
-->
|
||||||
|
<script src="js/impress.js"></script>
|
||||||
|
<script>impress().init();</script>
|
||||||
|
|
||||||
|
<!--
|
||||||
|
|
||||||
|
The `impress()` function also gives you access to the API that controls the presentation.
|
||||||
|
|
||||||
|
Just store the result of the call:
|
||||||
|
|
||||||
|
var api = impress();
|
||||||
|
|
||||||
|
and you will get three functions you can call:
|
||||||
|
|
||||||
|
`api.init()` - initializes the presentation,
|
||||||
|
`api.next()` - moves to next step of the presentation,
|
||||||
|
`api.prev()` - moves to previous step of the presentation,
|
||||||
|
`api.goto( idx | id | element, [duration] )` - moves the presentation to the step given by its index number
|
||||||
|
id or the DOM element; second parameter can be used to define duration of the transition in ms,
|
||||||
|
but it's optional - if not provided default transition duration for the presentation will be used.
|
||||||
|
|
||||||
|
You can also simply call `impress()` again to get the API, so `impress().next()` is also allowed.
|
||||||
|
Don't worry, it wont initialize the presentation again.
|
||||||
|
|
||||||
|
For some example uses of this API check the last part of the source of impress.js where the API
|
||||||
|
is used in event handlers.

Now you know more or less everything you need to build your first impress.js presentation, but before
|
||||||
|
you start...
|
||||||
|
|
||||||
|
Oh, you've already cloned the code from GitHub?
|
||||||
|
|
||||||
|
You have it open in text editor?
|
||||||
|
|
||||||
|
Stop right there!
|
||||||
|
|
||||||
|
That's not how you create awesome presentations. This is only a code. Implementation of the idea that
|
||||||
|
first needs to grow in your mind.
|
||||||
|
|
||||||
|
So if you want to build great presentation take a pencil and piece of paper. And turn off the computer.
|
||||||
|
|
||||||
|
Sketch, draw and write. Brainstorm your ideas on a paper. Try to build a mind-map of what you'd like
|
||||||
|
to present. It will get you closer and closer to the layout you'll build later with impress.js.
|
||||||
|
|
||||||
|
Get back to the code only when you have your presentation ready on a paper. It doesn't make sense to do
|
||||||
|
it earlier, because you'll only waste your time fighting with positioning of useless points.
|
||||||
|
|
||||||
|
If you think I'm crazy, please put your hands on a book called "Presentation Zen". It's all about
|
||||||
|
creating awesome and engaging presentations.
|
||||||
|
|
||||||
|
Think about it. 'Cause impress.js may not help you, if you have nothing interesting to say.

||||||

Are you still reading this?

For real?
|

|

I'm impressed! Feel free to let me know that you got that far (I'm @bartaz on Twitter), 'cause I'd like
|

|
to congratulate you personally :)
|
||||||
|
|

But you don't have to do it now. Take my advice and take some time off. Make yourself a cup of coffee, tea,
|

or anything you like to drink. And raise a glass for me ;)
