Here is an example of using the Grid 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-grid container>
<uwc-grid xs="6" sm="12" md="3" lg="4">
<uwc-text-field label="First Name"></uwc-text-field>
</uwc-grid>
<uwc-grid xs="6" sm="12" md="3" lg="4">
<uwc-text-field label="Middle Name"></uwc-text-field>
</uwc-grid>
<uwc-grid xs="6" sm="12" md="3" lg="4">
<uwc-text-field label="Last Name"></uwc-text-field>
</uwc-grid>
</uwc-grid>
</body>
</html>
