Download the lorem.js file and add the script reference to the head of your html file:
<script src="lorem.js"></script>
Whenever you need some placeholder text, call a new script tag, along with the lorem function and how many words you need. For example - 10:
<script>lorem(10);</script>
Would produce something like:
Donec sollicitudin, mi in ultrices tincidunt, nisl libero gravida sem.
That's it!
Because I'm too lazy to Google new placeholder text every time I want some, and wanted to prove that you don't need large plugins or packages to make this work.
