Full width/bleed horizontal rule?

Site URL: http://www.pitchurethis.com

Anyone know how to create a full bleed (but fixed) horizontal rule? Basically looking to create a page divider.

currently using the following css:

Quote

hr {

    margin: 0 -200px !important;

  }

the hr, for some reason, increases the actual width of the entire webpage, when I'd just like it to fit the standard page (responsively). Tried "position:fixed;" but it did not help.

Any help would be appreciated. Thanks!

width: 100% !important;
