Example 2: css centraliz page
Use a container element and set a specific max-width.
A common width many websites use is 960px.
To actually center the page, add margin: auto.
The following example will center the website on screens that are wider than
500px.On screens that are less than 500px wide,
it will span the whole of the page:
<style>
.content {
max-width: 500px;
margin: auto;
}
</style>
<body>
<div class="content">
</div>
</body>
