Newb seeking help - Strange coloured bar

[eluser]Unknown[/eluser]
Hi and thanks for your time,

That's correct. It was initially a html5/bootstrap template but I really like wanted to learn how to develop using a php framework and settled on CodeIgniter as a good intro. Also considered CakePHP/Zend but soo many seem to race about the CI community and docs. So far so good.

Everything had been running fine and I would presume that this is a css issue. It seems to appear whenever I try to implement the email class. I followed the docs <a href="http://ellislab.com/codeigniter/user-guide/libraries/email.html" target="_blank">here</a> but keep hitting a 404 despite the page/controller being created. When I attempt to submit the form, I then experience the coloured/speckled issue.

Thanks
