With the initial questions out of the way, Wix will ask you if you trust the ADI enough to let it build an example website for you, or if you want to build everything by hand. Going with the ADI is a much more efficient approach, especially since you can come back later on and customize every little detail of your site. You’re not stuck with the initial suggestions that Wix gives you.
Users can also use search engines such as Google to find images for your site, including social icons. One thing to always remember is copyright. Not every image on Google Images is subject to copyright but most are. Some images may be allowed for non-commercial re-use and others may not be labelled to re-use commercially. Some you may not be allowed to re-edit yourself. You should always watch out for this. On Google you can get around this by clicking on tools and changing the usage rights. This filters images a user can use on their site.
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.
