CSS just won't load.

[eluser]Todlerone[/eluser]
Hello everyone and thank-you in advance for any help/suggestions. Put simply I can't get my CSS to load no matter what I do. Currently I have created a css directory at the same level as my system folder.

I have autoloaded these:
$autoload['helper'] = array('url','html');
and this is in my header view
<?php echo link_tag('css/default.css');?>

When I look at the scource code for my website it appears like it should, it's just not formatted as per css.

Cheers

I got it to work. Turns out my .htaccess wasn't right. It still doesn't remove the index.php but my css loads now????

I couldn't get htaccess to work either, though I should say I'm using Mamp on a local machine. I hope I can get rid of index.php once this is uploaded offsite.
