Fitts's law (often cited as Fitts' law) is a model of human movement primarily used in human–computer interaction and ergonomics that predicts that the time required to rapidly move to a target area is a function of the distance to the target and the size of the target. Fitts's law is used to model the act of pointing, either by physically touching an object with a hand or finger, or virtually, by pointing to an object on a computer monitor using a pointing device.

It was proposed by Paul Fitts in 1954. Model[edit] Fitts's law has been formulated mathematically in several different ways. One common form is the Shannon formulation (proposed by Scott MacKenzie, professor at York University, and named for its resemblance to the Shannon–Hartley theorem) for movement along a single dimension: where: T is the average time taken to complete the movement. Success and implications[edit] Fitts's law is an unusually successful and well-studied model. In its original and strictest form: where Notes[edit] Responsive Web Design.

The English architect Christopher Wren once quipped that his chosen field “aims for Eternity,” and there’s something appealing about that formula: Unlike the web, which often feels like aiming for next week, architecture is a discipline very much defined by its permanence. Article Continues Below A building’s foundation defines its footprint, which defines its frame, which shapes the facade. Each phase of the architectural process is more immutable, more unchanging than the last. Creative decisions quite literally shape a physical space, defining the way in which people move through its confines for decades or even centuries. Working on the web, however, is a wholly different matter. But the landscape is shifting, perhaps more quickly than we might like.

Finsta left a question in the forums: I am fairly new to web design and I could never master the differences in positioning of elements. I know there are absolute, fixed, and relative. Is there any others? Also do they majorly differ? And when should you use which? Short answer: Yes, there is one more, "static", which is the default. Medium answer: I'm not going to do a "long answer" because there is no need to rewrite what has been written many times before, but I will do a "medium answer" here were we can quickly run through each type.

An important concept to understand first is that every single element on a web page is a block. Now that you are picturing every single page element as a block of pixels, we can talk about how positioning is used to get the blocks of pixels exactly where you want them to go. Static. Share On. Learn CSS Positioning in Ten Steps: position static relative absolute float. 1. position:static The default positioning for all elements is position:static, which means the element is not positioned and occurs where it normally would in the document. Normally you wouldn't specify this unless you needed to override a positioning that had been previously set. 2. position:relative If you specify position:relative, then you can use top or bottom, and left or right to move the element relative to where it would normally occur in the document.

Let's move div-1 down 20 pixels, and to the left 40 pixels: Notice the space where div-1 normally would have been if we had not moved it: now it is an empty space. It appears that position:relative is not very useful, but it will perform an important task later in this tutorial. 3. position:absolute When you specify position:absolute, the element is removed from the document and placed exactly where you tell it to go. Let's move div-1a to the top right of the page: What I really want is to position div-1a relative to div-1.
