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.

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

Random CSS Property

float

The float CSS property places an element on the left or right side of its container, allowing text and inline elements to wrap around it. The element is removed from the normal flow of the page, though still remaining a part of the flow (in contrast to absolute positioning).
