Blogs: Hide blog title when using an image

When you add a Featured Image banner for the main blog index page, the main title of the blog section is positioned over the image. If you'd like to remove this title, you can use this customization. 

Code to use:

/* -- code to remove main blog page title over image -- */
.template-blog h1.title--flex {display:none}
/* - end - */
