A

Same spot. Nothing changes.

20
Q

How does settingposition: absoluteon an element affect document flow?

A

It doesn’t affect the document flow at all. The idea of the value “absolute”, is that the box is taken out of normal flow and no longer affects the position of other elements on the page.

21
Q

How does settingposition: absoluteon an element affect where it appears on the page?

A

Position absolute takes the document out of the document flow. This means that it no longer takes up any space like what static and relative does. When position absolute is used on an element, it is positioned absolutely with reference to the closest parent that has a position relative value.

22
Q

How do you constrain an absolutely positioned element to a containing block?

A

Change the position to fixed.

23
Q

29
Q

List the three selector types in order of increasing specificity.

30

Transition-duration: sets the length of time a transition animation should take to complete. By default, the value is 0s, meaning that no animation will occur.
Transition-timing-function: sets how intermediate values are calculated for CSS properties being affected by a transition effect.

36
Q

What is abreakpointin responsive Web design?

A

A breakpoint is the“point” at which a website’s content and design will adapt in a certain wayin order to provide the best possible user experience. Instead of catering to every specific dimensions for every specific device, breakpoint caters to specific needs when every range is catered for.

37
Q

What is the advantage of using a percentage (e.g.50%)widthinstead of a fixed (e.g.px)widthfor a “column” class in a responsive layout?

A

Percentages are fluid. Pixels are fixed so therefore will cause complications when dealing with different layout sizes.

38
Q

If you introduce CSS rules for a smallermin-widthafterthe styles for a largermin-widthin your style sheet, the CSS rules for thesmallermin-widthwill “win”. Why is that?

A

Because in CSS, the style sheets cascade by order of importance.
The key is do order each ruleset from smallest width to largest width.
