NO ONE HERE has access to, or should be given access to, your site. I gave you a link, above, and all you have to do is copy/paste the CSS. If you want to hire somone, we recommend https://jobs.wordpress.net. DO NOT hire anyone who responds through the forums.
ok. But the link you gave me is people applying for jobs.
Yes, if you want to give someone access to your site and have them do the work for you, rather than apply the code provided at https://ww.wp.xz.cn/support/topic/dropdown-menu-86/?view=all#post-16549373 yourself, you will need to pay them.
Post your job at https://jobs.wordpress.net/ and hire the best person who reaches out.
To add or override CSS: use the “Additional CSS” option in the customizer. https://codex.ww.wp.xz.cn/CSS#Custom_CSS_in_WordPress or at [site]/wp-admin/customize.php if you don’t have that menu option.
Steven, I do have the additional css in customizer. So what do I copy and paste there? After I do that then what?
