<!DOCTYPE html>
<html>
<head>
<style>
.mydiv {
text-align-last: right;
}
</style>
</head>
<body>
<h1>text-align-last Property</h1>
<div class = "mydiv">
<p>This is demo text. This is demo text. This is demo text. This is demo text. This is demo text. This is demo text. This is demo text. This is demo text.</p>
</div>
</body>
</html>
