I'm doing Chris's Creating and Editing Custom Themes from Lynda.com and using the exercise files and am having a lot of trouble with the links and paths to files and images. For example, Chris puts the product.css file in the theme and links to it from the header using

<?php if (is_page_template('page-product.php')) { ?>	
    <link rel="stylesheet" href="<?php bloginfo('template_url'); ?>  /css/product.css">
    <?php } ?>

If I put it in the same place and use the same link, it doesn't link.
I have tried putting it in the root of the theme like style.css and linking with either /product.css or product.css , still no joy
The only way I can get it to show is to paste the css into the style.css

The .htaccess file is as follows:
[code]# BEGIN WordPress

RewriteEngine On
RewriteBase /widgetcorpWP/
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /widgetcorpWP/index.php [L]

# END WordPress
[/code]

Am I right in thinking that this has something to do with it? Any ideas, this is driving me nuts.
