How to click open a pen in Full Page View
by default please? For example, I would like to open below pen in full page view.
codepen.io/Hance/pen/aLjrJJ
A simple google search would have sufficed in this case, but anyway
You can access the Full Page view of any Pen from the "Change View" menu in the header. - Codepen Blog
To directly view the pen in full page, use /full/
in your link
codepen.io/Hance/full/aLjrJJ
