Hi @jehan! You can definitely do this. All you have to do is go to your blog’s Customize settings and add some code to the Custom JavaScript. There are two options depending what you’d like to do.
If you want to simply replace the text:
x = document.querySelector('footer').getElementsByTagName('nav')[0];
x.innerText = 'published with my hands';
If you want to add links or styling:
x = document.querySelector('footer').getElementsByTagName('nav')[0];
x.innerHTML = 'published with my <i>hands</i>'
Hope that helps! Would be glad to clarify anything in the code if need be.
