it moves the element to whatever spot you want it to go. ex-top, left, bottom, right

it is taken out of the document flow essentially, it does not affect surrounding elements, its as if they ignore the space that shouldve been there.

What are the four components of “the Cascade”.
Source Order
Inheritance
Specificity
!important
What does the term “source order” mean with respect to CSS?
the order that your css rules are written in the stylesheet.
The styling provided for an element last in your stylesheet is the styling that will ultimately take effect.
How is it possible for the styles of an element to be applied to its children as well without an additional CSS rule?
use inheritance because it allows child elements that have no style on it to inherit the style of its parent.
List the three selector types in order of increasing specificity.
ID - (only ID selectors) CLASS - (includes .class selectors, pseudo classes, also attribute selectors like type="radio") TYPE - (such as p, h1, td)
Why is using !important considered bad practice?
Understanding and effectively using specificity and the cascade can remove any need for the !important style.

depending on how wide your screen is the column will always be 50% of the screen your using.
If you introduce CSS rules for a smaller min-width after the styles for a larger min-width in your style sheet, the CSS rules for the smaller min-width will “win”. Why is that?
the source order.
