A legitimate use: a utility that must always win

Practice questions
Write the code in the editor, run it, then open the model answer to compare.
The CSS is #nav a { color: gray; } and .active { color: tomato; }; the active link in #nav stays gray. Fix it two ways without !important.
Write a .visually-hidden utility that is always hidden from sight (but still readable by screen readers) and can't be broken by other rules setting position or width.
Explain it without notes
Where does !important act in the cascade, and what does it beat?
Two declarations are both !important. How is the winner chosen?
Why does the origin order flip for important declarations?
Give three ways to fix a losing rule without !important, and two cases where !important is the right tool.
