social media links are lost

Hi! I hope someone can help me. Recently i used an css code from this forum to place my logo in the middle of my header. While doing that i knew this would remove my social media links and search bar from my header. After looking at this new design, i didn't like my logo in the middle so i removed the css code again. My logo is now back on the left side of my header where I want it. But....my social media links and search bar are not coming back in my header. Please help?!
