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. ☕

therock Somewhere along this crazy road I learned (often times the hard way) the most important things I can do is be authentic, trust my gut, be the hardest worker in the room, celebrate the mistakes, be a grateful man and always remember that it's nice to be important, but it's more important to be nice.

Random CSS Property

grid-row

The grid-row CSS shorthand property specifies a grid item's size and location within the grid row by contributing a line, a span, or nothing (automatic) to its grid placement, thereby specifying the inline-start and inline-end edge of its grid area.
