Until recently whenever I had to do the simplest animation I always had to use JavaScript code.
If you're using jQuery it's pretty easy to make simple effects.
The most known ones would probably be slideDown() and slideUp().
Custom animation is also pretty easy with jQuery:

$('div.red').hover(function() {
    $('div.red').animate({
    width: '+=50',
    height: '+=50'
    }, 200)
},
function() {
    $('div.red').animate({
        width: '-=50',
        height: '-=50'
    }, 200)
});

After looking into bitcoins (on and off) for over 2 years, and finally started to accept bitcoins, I've added some Bitcoin news sites to my feed.

Local Storage (or Web Storage), is a simple yet very powerful feature of HTML5, that is pretty much supported across the board
by now, as in, by almost all browsers.
In essence, Local Storage lets you store information for a long period of time (more on that in a bit).
This has many uses, especially for Web Apps.

In the past 10 years (or so), I've been taking old
computers (desktops, laptops), and putting Linux on them.
Mainly because Microsoft's philosophy with Windows is a very one size fits all approach, and also because Windows had a general bad reputation when it comes to old machines (security holes, anyone?).
As for friends & family, it was also very difficult for me to convince them that if they'll switch, they could get 2+ more years out of their machines.
