I'm using wordpress and am attempting to connect to the stylesheet:

<link rel="stylesheet" href="<?php bloginfo('stylesheet_url'); ?>" type="text/css" media="screen" />

It's not realizing that link tag, because I believe the bloginfo('stylesheet_url') part isn't working properly.

How can i set the position of the stylesheet url in wordpress?

This is exactly what ought to be specified:

<link rel="stylesheet" href="<?php bloginfo('stylesheet_url'); ?>" type="text/css" />

You're indicating properly, make certain you have place the CSS file within the cause of your theme folder and also the CSS file is known as style.css
