I have been playing about on codepen for a while and can’t get simple html and css to work as intended.
As a test, I’ve now copied and pasted some code directly from w3schools and it still appears incorrectly.
It seems that Codepen is ignoring positioning? or adding margins? What am i doing wrong?
This is what it should look like though: https://www.w3schools.com/howto/tryit.asp?filename=tryhow_css_timeline
