Popup window after clicking a button

[Lajos]

Hi, I need some help. I want to make it so that when I click on the "Contact us" button, a page opens in a small popup window. Can someone please help me? 

Url:

https://www.energetikon.com/products/canadian-solar-cs6l-455ms

My theme: Colorblock v.14.0.0

I am using this Liquid code:

<a href="https://www.energetikon.com/pages/contact" class="button button--primary" onclick="window.location.href = this.href">Contact us</a>

<script>
function openInPopup(link) {
  
}
</script>

Hi!

This can be done with a custom solution.
