Hello guys! I have been going through the curriculum material and I enountered a problem on the third project of the Responsive Web Design Certficate. I tried to copy and paste the html and css code on two seperate files locally on my pc and connect them with these lines in the htm document.

<link rel="stylesheet" type="text/css" href="original.css">

The thing is that the page doesn’t show up like in codepen. I’m testing the example given, not my implementation. The result is this:

The yellow signs warn about “unknown property name” or “invalid property value”. Why is this happening? I kind of lost my motivation by not being sure that what I create in code pen works flawlessly…

This is my header

This is my paragraph


I’m new to coding; I started the lessons on freecodecamp
