The CSS rules are placed inside a <style> block within the HTML file. According to the best practices in the PR description, CSS should be in separate files to avoid mixing it with HTML and to improve maintainability.

critical

The grading logic has a few issues:

  1. Invalid Input Handling: The else block for "Invalid Input" is unreachable for many invalid cases. For example, an empty input is converted to 0 and graded as "F". The logic should explicitly check for empty or non-numeric inputs.
  2. Range Validation: There's no validation for marks outside the typical 0-100 range.
  3. Redundant Conditions: In else if statements like marks >= 75 && marks <= 89, the marks <= 89 part is redundant because the previous if already handled marks >= 90.

These issues can lead to incorrect grades for certain inputs.

Suggested change
if (marks >= 90) {
grade = "A";
} else if (marks >= 75 && marks <= 89) {
grade = "B";
} else if (marks >= 50 && marks <= 74) {
grade = "C";
} else if (marks < 50) {
grade = "F";
} else {
grade = "Invalid Input";
}
if (isNaN(marks) || marks < 0 || marks > 100 || document.getElementById("marks").value.trim() === "") {
grade = "Invalid Input";
} else if (marks >= 90) {
grade = "A";
} else if (marks >= 75) {
grade = "B";
} else if (marks >= 50) {
grade = "C";
} else {
grade = "F";
}



document.getElementById("result").innerHTML = `Grade: <strong>${grade}</strong>`;
