Problem with CSS code

its the underline tag

got a solution for it.
i made a modification in the style.css file.
in line 22 i changed from

i, em , u {font-style: italics;}

to

i, em  {font-style: italics;}
u {font-style: normal;}

changed

u {text-decoration: none;}

to

u {text-decoration: underline;}
