getting crazy with ems
I am a big fan of using em sizes in css but sometimes is a little bit hard to get the correct conversion into the more readable px format.
here is a link to a web tool that does the conversion for you:

Interaction design patterns
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?
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
<div> which contains a <span> which contains an <img alt="" />. 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
<div>'s event listener. The event then goes to the <span>, and finally to the <img alt="" />. 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 <img alt="" /> inside a
<span> , which is inside a <div>, 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 <img alt="" />, gets to see the event first, and then passes it upwards to the <span> for further processing, which passes it on to the <div> , which finally passes it up to the document.
