Most likely  as mentioned by others  it is a class carrying the css values    clear clear  both     in order to prevent any more page elements from extending into the footer element  It is a quick and easy way of making sure that pages with columns of varying heights don t cause the footer to render oddly  by possibly setting its top position at the end of a shorter column   In many cases it is not necessary  but if you are using best-practice standards it is a good idea to use  if you are floating page elements left and right  It functions with page elements similar to the way a horizontal rule works with text  to ensure proper and complete sepperation

A class in HTML means that in order to set attributes to it in CSS  you simply need to add a period in front of it  For example  the CSS code of that html code may be    clear       height  50px      width  25px      Also  if you  as suggested by abiessu  are attempting to add the CSS clear  both  attribute to the div to prevent anything from floating to the left or right of this div  you can use this CSS code    clear       clear  both
