Beauty salon site in HTML 5
meta-charset should come before title

The meta-charset element would ideally be the first element in head (details about the order in head).

So it could be:

&lt;head&gt;
  &lt;meta charset="utf-8"&gt;
  &lt;title&gt;Salon Sociel | Hair-Nails-Unisex&lt;/title&gt;
  &lt;link rel="stylesheet" href="style/main.css"&gt;
&lt;/head&gt;


Wrong use of section and h3

You have:


&lt;section class="logo"&gt;
  &lt;h1&gt;Salon Sociel&lt;/h1&gt;
  &lt;h3&gt;Hair-Nails-Unisex&lt;/h3&gt;
&lt;/section&gt;



Neither is the section correct here (it only contains headings, and by using it the h1 is no longer the heading of the body), nor is it correct to use a heading element for a subheading (details).

So it should simply be:

&lt;h1&gt;Salon Sociel&lt;/h1&gt;
&lt;p&gt;Hair-Nails-Unisex&lt;/p&gt;


(Your structure would have been correct if using hgroup instead of section, but this element was removed from W3C’s HTML.)
