XF 1.5 Avatar dimensions increasing


Active member
I have searched many threads here how I can increase the Hight and width of default avatar in the posts and also the size of the info box under avatar according to the avatar dimension. And I also tried those tricks but end up with breaking layout or CSS issues. Maybe they are outdated, that's why I'm making this thread to get the fresh codes which work perfectly with the current XF version.
By the way I'm using default theme. Appreciate your prompt response.

Kindest regards,
