General advice, built from the definition and example above

Code pattern: “selector { property: value; } with comments in /* */.” Then apply it: .red-text { color: red; }

In a short answer, give the definition in your own words first, then tie it to the situation in the question. Do not copy the example above unless it fits the scenario.

What the marking guidelines and feedback say

Sample exam Q16a (1 mark): CSS (id v class) · contains a reasoned or flagged note, read it as such

FLAG: the NESA MG prints the answer as 'The id "se_item" ...' while the question printout says "qe_item". This is an official inconsistency; the option is the 'id ... not correctly referenced' one. Fix: use class="qe_item" in the HTML or #qe_item in the CSS.

General advice
  • Use the term exactly as the syllabus words it, then link it to the scenario in the question; the 2025 feedback repeatedly rewards using the stimulus.
  • Answer the command word: outline gives main points only, explain gives a reason or cause, discuss gives both sides.
