Why isn’t my link attribute getting my css?

 <link href="https://wordpress.stackexchange.com/questions/161307/<?php bloginfo("stylesheet_url');?>"rel="stylesheet" type="text/css"/>

Just Copy and Paste above code.

Hata!: SQLSTATE[HY000] [1045] Access denied for user 'divattrend_liink'@'localhost' (using password: YES)
