I’d like someone to help me with the table. I tried to expand the first (empty) header onto 2 columns, in order to put Jovian planets and Gas/Ice planets under one header, but it resulted into puting all planets (except Jovian ones) under this same header. Please, explain where I did a mistake
It’s correct to expand the empty cell (which should be a <td>) to two columns. Now you also have to add colspan="2" to “Terrestrial planets” and “Dwarf planets*”.
I hope that brings you further in the exercise. Please tell me if you have more questions or you want me to assess your whole work.
I’m glad it was helpful! If you have updated your JSFiddle and want me to have a final look, you need to post the new link. (On JSFiddle every time you save the URL changes)
