      <div class="faq-answer">
        <p>Glassmorphism is a UI design trend that uses background blur, transparency, and vibrant borders to create a frosted glass effect.</p>

    <div class="faq-item">
      <div class="faq-question">
        <h3>How is the blur effect achieved?</h3>
        <div class="question-icon">+</div>
      </div>
      <div class="faq-answer">
        <p>The blur effect is created using the CSS backdrop-filter property with a blur value, combined with semi-transparent backgrounds.</p>
      </div>
    </div>
    
    <div class="faq-item">
      <div class="faq-question">

        <div class="question-icon">+</div>
      </div>
      <div class="faq-answer">
        <p>Yes, we've implemented proper contrast ratios, keyboard navigation, and ARIA attributes for accessibility.</p>

    <div class="faq-item">
      <div class="faq-question">
        <h3>Can I customize the colors?</h3>
        <div class="question-icon">+</div>
      </div>
      <div class="faq-answer">
        <p>Absolutely! The component uses CSS custom properties that make it easy to change colors, blur intensity, and borders.</p>
