Cutsom HTML block

Hi everyone, how can I create a custom html block. I want to add a custom html code into my footer part of my website. How can I do it?

If you go to Online Store, Themes and click the three dots and select Edit code. In there you will find footer.liquid under sections, here you can place the html code.

Hope this helps

Thanks BlackCro. But what’s the HTML code to insert into footer.liquid in order to make a custom block option?
