Coding Details:
Behind the scenes, the Genetics Quiz is powered by HTML, CSS, and JavaScript. Let's delve into the coding that makes this interactive quiz possible:
HTML Structure: The HTML structure defines the layout of the quiz. It includes a title, question container, options container, result display, and a "Next" button.
JavaScript Magic: JavaScript brings the quiz to life. It maintains the current question, calculates the score, and handles user interactions. For example, when you click an option, JavaScript checks if it's correct, updates the score, and loads the next question.
Question Bank: The quiz comprises a set of questions stored in an array. Each question includes the question itself, answer options, and the correct answer.
Dynamic Content: JavaScript dynamically replaces the question and answer options based on the current question. It ensures a smooth and interactive user experience.
Result Display: As you progress through the quiz, your score is displayed. Once you've answered all the questions, the quiz concludes.
