Match what is told still wrong though

Hello World

I didn’t think it was very unclear until I tried every variation I could come up with and they were all wrong… So, where am I going wrong??
I have tried upper case where it shows uppercase, with the h1, without the h1, spaces, adding / after

Clearly I am doing everything wrong here! I put the items in the place they say to add them as well have tried numerous variations of it ie; with caps as shown, without caps where shown caps, with and with out spaces, with adding </ of my own before and after… I didn’t think it was that difficult but obviously I am doing something wrong here. What is the magical sequence??
