I could not get it to work after updating the cahce the css did not appear in the homepage, do you have the full Content.php file please.

Yes, sure. It will look like this:

<?php

namespace XLite\Module\Tony\HomePageWithoutSidebar\View;

class Content extends \XLite\View\Content implements \XLite\Base\IDecorator
{
	protected function isSidebarFirstVisible()
	{
		if ('main' == $this->getTarget()) {
			$return = false;
		} else {
			$return = parent::isSidebarFirstVisible();
		}

		return $return;
	}

	public function getJSFiles()
	{
		$result = parent::getJSFiles();

		if ('main' == $this->getTarget()) {
			$result[] = 'modules/Tony/HomePageWithoutSidebar/css/css.css';
		}

		return $result;
	} 

}

Please do not forget to add the following CSS file:
skins/default/en/modules/Tony/HomePageWithoutSidebar/css/css.css
