How can i add a cut line instead of normal line?

What do you mean by a "cut line"? Do you have a specific example of what you want? Are you talking about a dashed line like this:

----------

<hr style="border: none 0;
border-top: 1px dashed #000;
border-bottom: 1px dashed #ccc;
width: 80%;
height: 2px;
margin: 10px auto 0 0;
text-align: left;">

That should give you a dashed line, as seen at the bottom of this page: http://www.blakems.com/experimental/hr/

Are you talking about a dashed line like this:

exactly

<hr style="border: none 0;
border-top: 1px dashed #000;
border-bottom: 1px dashed #ccc;
width: 80%;
height: 2px;
margin: 10px auto 0 0;
text-align: left;">

thanks alot
