Twenty Seventeen Child Theme Issue

Hi

Total newbie here!

I have created a child theme folder (twentyseventeen-child) in the themes folder.

Inside the child theme folder, I have created a style.css file and a functions.php file.

It looks like my style.css and functions.php file aren’t being called properly.
What have I done wrong?

functions.php file....
add_action ("wp_enqueue_scripts", "theme_enqueue_styles");

function theme_enqueue_styles() 
{
     wp_enqueue_style ("parent-style", get_template_directory_uri() . "/style.css");
     wp_enqueue_style ("child-style", get_stylesheet_directory_uri() . "/style.css", array("parent-style"));
}

function hsl_breadcrumbs() 
{   
	...my code here (tested this function in main theme functions.php file and it works.
}

.style.css file....
/*
Theme Name:     	Twenty Seventeen Child Theme
 Author:         	KW
 Template:       	twentyseventeen
 Version:        	1.0.0
*/

/* HSL Breacrumb Navigation  */
.breadcrumb{
    width:645px;
    float:left;
    padding:0 0 0 47px;
    margin:9px 0 0 0;
    font-size:90%;
    clear:both;
}

.delimiter{
    color:#000;
    background-color:inherit;
}

.delimiter1{
    color: #627FC3;
    background-color:inherit;
}
