Help learning about scroll anchors pls

Hi

I'm very very new to html sorry and i'd like my forum to auto scroll to the top of post or threads when changing pages etc.

Meaning when i click on a board it will scroll straight down to the threads rather than the top of the page.


I'm very very new and i wouldn't even know where to start sorry, but i kinda know it's a code i can just put in the header that auto scrolls half way down with the scroll bar and anchor  ... idk sorry.


How would i do this pls ? or can i request one ? and learn at the same time


thank you  http://jedsblog.tk/PotAds
