Hello,
Thank you for your response.
1. I want to put youtube link with anothers socials link on header and footer
2. Ok, it works, thank you!
3. There is a problem with the email: when I clik on the email links a new blank window open with this URL:mailto:info@kitkasa.com. I just want a “normal” email, without windows, it should be opened only with the outlook (or another manager).
4. BACKGROUND VIDEO: Is it possible? 
5. BLOG: I wll try to change the margin beetween posts, but it changes the entire column, I really like the desing of recent post widget
Sorry for my english, and thanks for your help.
