I'm trying to implement a CSS-only modal box with animation onto my website. It works perfectly on this Codepen I found: http://codepen.io/petebot/pen/DBvKj
But I can't test or customize this code on my website because it doesn't work on an HTML page.
What am I missing here?
Here's the HTML page:
<html>
<head>

The problem is that you have the styles in LESS format. LESS is a CSS pre-processor. Is not supported natively by the browser. You should compile your LESS styles to CSS and then add those styles to your page.
In codepen the code works because the CSS panel is configured to use LESS but is just a codepen feature, sadly you can't do it for your site / page.
Check out LESS docs to see how to compile it to a valid CSS.
Try this to get the compiled css
Click on the settings button just beside the css tab.
Then click on Analyze css and then on Clear css errors.
You will now have the compiled css.
Use this css on the html file.
