Answer 1

I'm pretty sure it can be done with:

<!-- other code here -->
<input type="checkbox" required>
<!-- other code here -->

This will automatically give an error popup message if the checkbox is not filled in.

Answer 2

Yes, you can apply the required attribute to a checkbox in HTML, even when you have multiple checkboxes.

<form>
    <div>
        <label><input type="checkbox" name="option" value="option1" required> Option 1</label>
    </div>
    <div>
        <label><input type="checkbox" name="option" value="option2" required> Option 2</label>
    </div>
    <div>
        <label><input type="checkbox" name="option" value="option3" required> Option 3</label>
    </div>
    <div>
        <label><input type="checkbox" name="option" value="option4" required> Option 4</label>
    </div>

    <input type="submit" value="Submit">
</form>
