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...

You could also follow me on twitter. I have a couple of youtube channels if you want to see some video related content. RuneScape 3, Minecraft and also a coding channel here Web Dev.

Random CSS Property

scroll-padding-inline-start

The scroll-padding-inline-start property defines offsets for the start edge in the inline 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.
