The twitter and facebook icons belong to "footer", while the images belong to "ul( being set be by 'float' )". They are separative. why do the icons float to the right side?

Treehouse Moderator 90,705 PointsOnce you put a float on an element it takes the element out of "normal document flow". So preceding elements will shift into the available space left where that element would otherwise be. To fix it, you need to clear the floats by putting a "clearfix" on that element.
.clearfix {
content: "";
display: table;
clear:both
}
This is an example of a clearfix. It attaches itself to any HTML element that has a class of "clearfix" and will put that element back into normal flow.
Hope this helps!
