15properties to guide this element (by giving some margins to the block),
16relative to what was the standard layout. This new position will not
17influence the distribution of other elements (the others will keep
18the standard layout, as if your element leaves a "shadow" of where it
19was supposed to be). Therefore, some overlaps and lack of coordination
20can occur when you move your element*/

35/* With this property, we are able to position the element relative
36to the <body> or relative to it's parent, IF the parent is itself isn't
37"static". Using the coordination properties, we do not increase or
38decrease the margins in relation to the standard position, but rather,
39we are increasing or decreasing the distance in relation to the "walls"
40of the block that contains this element, for example, a parent <div>
41that contains a <h1> element. The name "absolut", comes from the cases
42where the parent is the <body> element. When you use this property,
43you are taking the element away from the natural flow of your document,
44so, the other elements position will not take into account your absolute
45element*/

106/* By default, the z-index of an element is zero, so if you change the
107z-index to something above or below that value, you are putting that
108element above or below the ones you didn't change.
109Another important thing to be aware of is that the z-index only worked
110for elements that have a position different from the standard. This
111means that, for elements with Static position, this won't work.
112So, you can only make two elements interact in the z plane if they both
113have a define position as: Relative, Absolute, Fixed, ... */
