A

Percentages are always consistent, whereas fixed widths will vary

26
Q

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?

A

Because that breakpoint is being reached before the larger breakpoint, negating the larger one’s styling

27

What are the four components of “the Cascade”.

A

Source order, inheritance, specificity, and !important

28
Q

What does the term “source order” mean with respect to CSS?

A

The order in which CSS rules are written in a stylesheet, with the last rule usually being applied if two rules contain the same styling

29
Q

How is it possible for the styles of an element to be applied to its children as well without an additional CSS rule?

A

Some CSS properties are set to inherited by default, meaning they are automatically applied to children elements

30
Q

List the three selector types in order of increasing specificity.

A

Type selectors, class selectors, id selectors

31
Q

Why is using !important considered bad practice?

A

It makes debugging more difficult because it breaks the natural cascading of the stylesheets
