Here is an example of using the Tab Bar in a plain html page:

<html>
<head>
<link href="https://developer.temenos.com/uux/base.css" rel="stylesheet" />
<script src="https://developer.temenos.com/uux/unified-ux-web.min.js"></script>
</head>
<body>
<uwc-tab-bar>
<uwc-tab label="Tab one" icon="accessibility" stacked></uwc-tab>
<uwc-tab label="Tab two" icon="exit_to_app" stacked></uwc-tab>
<uwc-tab label="Tab three" icon="star" stacked></uwc-tab>
</uwc-tab-bar>
</body>
</html>
