What are the potential pitfalls of using JavaScript and CSS layers for tabbed displays in a website?

Potential pitfalls of using JavaScript and CSS layers for tabbed displays include accessibility issues for users who rely on screen readers or keyboard navigation, performance concerns due to excessive DOM manipulation, and potential conflicts with other scripts or styles on the page. To address these issues, consider using semantic HTML markup for tabs, progressive enhancement techniques to ensure basic functionality without JavaScript, and optimizing CSS styles for performance.

<!-- Example of using semantic HTML markup for tabs -->
<div class="tabs">
    <button class="tab" onclick="openTab('tab1')">Tab 1</button>
    <button class="tab" onclick="openTab('tab2')">Tab 2</button>
    <div id="tab1" class="tab-content">
        Tab 1 content
    </div>
    <div id="tab2" class="tab-content">
        Tab 2 content
    </div>
</div>
