Remove page title and vertical grey lines

Site URL: https://www.orientlinenco.com/shop

Hi,

I'd love some help removing the vertical gray lines between shop categories navigation. I've tried the below two codes and neither of them work.

I also can't seem to figure out how to remove the page title from my shop page above the category navigation. It feels redundant to have "shop" in navigation at top left and then have "shop" again as the title of the page. I'd like to then reduce the space between the header and the content on the page.

And I am not able to change the font and color of the product names on my main shop page. 

Thank you

 

/* Hide Line */
span.category-filter-delimiter.has-category {
    display: none;
}

ul.nested-category-children:after {
    display: none !important;
}

If possible, can you share code for other members ;) thank you
