Mailto
A help forum user asked:
"I want to add an email button which shares my website link. How can I do this?"
Below is a HTML/CSS button that links to:
"mailto:?subject=Look at this website&body=Hi, I found this website and thought you might like it - https://sitesguide.perjury.info"
(Unfortunately adding it as a simple link does not seem to work in Sites. At the time of writing this has been identified as a bug which should be fixed one day appears to have been fixed)
Below is the full html embed code I used. Details of how to style CSS buttons can be found here https://www.w3schools.com/css/css3_buttons.asp
<!DOCTYPE html>
