Multiple CSS files for each .php file (IFELSE)

I have 6 different pages on my website, however I want each page to have very different CSS.

This is what I currently have in the header, however I notice some CSS happens on other pages when it shouldn’t.

<link rel="stylesheet" href="<?php bloginfo('stylesheet_url'); ?>" type="text/css" media="screen" /> 

<?php if ( is_page_template( 'front-page.php' ) ) { ?>
<link rel="stylesheet" href="<?php bloginfo('front-page.css'); ?>">
<?php
} elseif ( is_page_template( 'home.php' ) ) { ?>
<link rel="stylesheet" href="<?php bloginfo('template_directory'); ?>/css/home.css" media="screen" type="text/css" />
<?php
} elseif ( is_page_template( 'digital.php' ) ) { ?>
<link rel="stylesheet" href="<?php bloginfo('template_directory'); ?>/css/digital.css" media="screen" type="text/css" />
<?php
} elseif ( is_page_template( 'print.php' ) ) { ?>
<link rel="stylesheet" href="<?php bloginfo('template_directory'); ?>/css/print.css" media="screen" type="text/css" />
<?php
} elseif ( is_page_template( 'video.php' ) ) { ?>
<link rel="stylesheet" href="<?php bloginfo('template_directory'); ?>/css/video.css" media="screen" type="text/css" />
<?php
} else {

}

?>

Any suggestions would be greatly appreciated.
