Validation

[Courtney513]

You have a couple warning about using multiple h1 in your index. Consider downgrading one of the h1 from h1 to h2 and then just style them using css. you had to two errors stating that the element link is missing a required attribute property. A Couple of easy fixes for would be to either move to the link from the body to head of the document or if you leave the link in the body you have to use property="stylesheet". Either way will validate and I have included some links below if you have any concerns.

Your css showed one error and ten warnings. The validator show this on line seventy-eight to be an error .hero p Value Error : font-family 1.75rem is not a font-family value : 1.75rem Museo. Eight of the ten warnings had to do with "unknown vendor extension." However, after reading some articles it appears that because they are browser specifics they just aren't included in standard css and aren't actually wrong. The other two warnings said that "Family names containing whitespace should be quoted." Here are some links I found for you to refer to.
