Welcome

This is my test area for webdev. I keep a collection of code here, mostly for my reference. Also if i find a good link, i usually add it here and then forget about it. more...

Subscribe to weekly updates about things i have added to the site or thought interesting during the last week.

You could also follow me on twitter or not... does anyone even use twitter anymore?

If you found something useful or like my work, you can buy me a coffee here. Mmm Coffee. ☕

Our brains are wired to find things we are looking for - if your always cynical or waiting for things to go wrong, then your life will reflect that. On the other hand, having a positive outlook on life will bring you joy and provide you with inspiration when you least expect it ☀️🍉🌴

Random CSS Property

scroll-padding-block-end

The scroll-padding-block-end property defines offsets for the end edge in the block dimension of the optimal viewing region of the scrollport: the region used as the target region for placing things in view of the user. This allows the author to exclude regions of the scrollport that are obscured by other content (such as fixed-positioned toolbars or sidebars) or to put more breathing room between a targeted element and the edges of the scrollport.
