To add social icons, you can simple use WIX free icons or icons from Google. To get icons from with, simply go to the add element once again and click on social. You will see the many icons including Facebook, Twitter, Google+, Instagram, Pinterest, YouTube and many more. Just drag and drop these icons from the social add element to the right part of your page.
Site Settings- Site settings are almost more important than any other part of the website. Without these settings your site won’t be published (If you don’t want a WIX domain) or be able to certain other elements to your site. Here you will find where to connect your sites domain name, if you would like your own. You will also where to add your sites favicon, a professional mailbox, analytics and much more.
A perfect example would be a photographers portfolio website. They may have different pages for different types of photos such as nature, cars even maybe something small such as street signs. Having a car page would mean, no images of nature should be in the gallery of the car page, unless the photo over laps each category. Then the photo could be an exception.
