Tiny font sizes in KALE PRO theme

Iam working thru some tricky areas of font sizes with my website and I am close to resolution. I have a problem with two arrows that can be seen beneath the body text on the linked page:

left arrow “previous page”
“next page” right arrow

I know how to change these fonts, but I don’t know what the script is to identify the previous arrow and next arrow on the front page

Lyratheme has provided the script for other arrows on a post page:

.pagination-post a { font-size: 25px;
}

.pagination-post .previous_post a::before { font-size:40px;
}

.pagination-post .next_post a::after { font-size:40px;
}

Can anyone help me?
