/* impress.js doesn't require any particular CSS file. 
Each author should create their own, to achieve the visual style they want. 
Yet in practice many plugins will not do anything useful without CSS. (See for example mouse-timeout plugin.) 
This file contains sample CSS that you may want to use in your presentation. 
It is focused on plugin functionality, not the visual style of your presentation. */

    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.
*/

.impress-enabled                          { pointer-events: none }
.impress-enabled #impress                 { pointer-events: auto }

 /*If you disable pointer-events, you need to re-enable them for the toolbar.
   And the speaker console while at it.*/

.impress-enabled #impress-toolbar         { pointer-events: auto }
.impress-enabled #impress-console-button  { pointer-events: auto }


/*
    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?
