I wonder what the html error was, showing 10 of 10 currently. missed that one. Maybe I changed it on the fly and didn’t notice.
The shorthand for the margins definitely seems like a good practice, could save a lot of writing.
The accessibility point is interesting, I wonder what it would be like to be using an electronic reader as opposed to a browser or phone.
Thank you for your points, and may your day be a good one. Best wishes for your musical interests, I have had a guitar near me at all times for 30 years.
So that only applies to passing the tests that FCC has setup. You should still run your code through an html validator to see if there are mistakes in the code.
One mistake is in line 18 with two opening p tags.
