UI design patterns are common behavioural patterns that users may find during their navigation throug a website pages.
In web design they are used a lot since they are useful for the user becouse they increase drastically the chance to success of a task.
I found a useful site which contains the most common, and used, interaction patterns with a rich explaination on how and when to use them.

Which is the difference between event capture and event bubbling?

admin — Sat, 12 Feb 2011 10:03:01 +0000

The DOM has two ways for objects to detect events: from the top down, and from the bottom up. The first method is known as event capture, the second is called event bubbling.

Event Capture
Let's say that your document contains a

which contains a which contains an . Further, let's say you've added an event listener to all of them. When a user clicks on the image, a mouseclick event occurs.

Even though the user clicked the image, the image doesn't get the event first. Instead, the event listener attached to the document grabs the event first and processes it. The event is then passed down to the

's event listener. The event then goes to the , and finally to the . That is, all of the clicked-on object's "ancestors" higher up in the document capture the event for processing before sending it down the chain to its intended target.

Event Bubbling
Now let's look at the same situation from the inside out. You have an inside a
, which is inside a

, which is inside your document. When a user clicks the image, this time the events rise like a bubble in a glass of water. The click's original target, the , gets to see the event first, and then passes it upwards to the for further processing, which passes it on to the

, which finally passes it up to the document.

Paper size in pixels

I'm doing some work for printed graphic so I was wondering how big is in pixel a paper sheet?
Of course depends on DPI usuallly the standard DPI rate is 300 but also lower resulution are fine for what I'm doing so let's see what happen playing with resolutions.

paper size	inch	pixel 300dpi	pixel 200dpi
A0	33.11 × 46.81	9933 x 14043	6622 x 9362
A1	23.39 × 33.11	6717 x 9933	4478 x 6622
A2	16.54 × 23.39	4962 x 6717	3308 x 4478
A3	11.69 × 16.54	3507 x 4962	2338 x 3308
A4	8.27 × 11.69	2481 x 3507	1654 x 2338
A5	5.83 × 8.27	1749 x 2481	1166 x 1654
A6	4.13 × 5.83	1239 x 1749	826 x 1166
