could u plz explain me the use of clearfix usuage when using ul and seperatiion of left and right header in css.
And the use of clear:both.
Clearfix is just one method
Clearfix is just one method of containing floats. clear:both is for clearing preceding floats. clear:left is if the preceding content is floated left, clear: right if it was floated right and clear: both if you need to clear floats in both directions.
