I would like when I add #exampleheader at the end of my link , to arrive directly at the header in my page like in github with this link : https://github.com/getgrav/grav#adding-functionality you arrive directly in the chapter “adding-functionality”. How can I do that please ? by default it doesn’t work
You just need to use named anchors within the page, as explained here. Similarly, for a link “to the top” you would add a <a name="top"></a> and <a href="#top">To the top!</a>.
