Hi Judy Asman,
Please use the following css to fix your issue:
#pref-cta a:hover {
color: #282828 !important;
}
Please use the class in ol (for eg:
) by editing the page, then use the following css:
ol#custom-listing {
color: black;
font-size: 15px;
}
Note: Please use the custom css plugin or child theme to write the css
Thanks
