Validation

[Courtney513]

HOMEPAGE
Your home page has nine errors and one warning. Your one warning is on line 25 and suggests you add an h1-h6. You have four errors on lines 132 through 135. You have you <li> inside of your <a>, but if you switch them around they will validate. Correct example: <li class="fi-social-facebook"> <a href="#"></a></li>.
On line 81 for your Instagram snap widget allowTransparency="true" frameborder="0" scrolling="no" for iframe is obsolete. The validator suggests using css or you could find a different widget. Also on line 81 your iframe src="" link has a ampersand in the url, try escaping using &

You have one error on line 107 stating that the element link is missing a required attribute property. A Couple of easy fixes would be to either move the link from the body to the 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 need to reference them.

MAIN.CSS

Your css is currently validating with no errors and had 8 warnings. The warnings state they have detected an "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. here are a couple of links I found for you to refer to.
