Adding a like/love button to a project page

Site URL: https://www.melvinraju.com/spiro

I want to add a simple like or love counter to my websites where visitors can like a project 
here's a similar "love" button example which has a heart button and the count above it.

It doesn't need to be floating like in the example but great if that is possible
