Thanks for your reply.
I’m using Elemntor but here is the CSS from the template (OceanWP).

/* Custom hover color to the trainers social icons */
.elementor-widget.custom-social .elementor-social-icon:hover { opacity: 1; background-color: #0eb290; border-color: #0eb290; color: #fff; }

/* Margin bottom to the subscribe title */
.elementor-widget.subscribe-tilte { margin: 0 0 10px; }

/* Placeholders color*/
#searchform-dropdown input::-webkit-input-placeholder,
body .sidr-class-mobile-searchform input::-webkit-input-placeholder { color: #81e4cf; }
#searchform-dropdown input::-moz-placeholder,
body .sidr-class-mobile-searchform input::-moz-placeholder { color: #81e4cf; }
#searchform-dropdown input:-ms-input-placeholder,
body .sidr-class-mobile-searchform input:-ms-input-placeholder { color: #81e4cf; }

/* Scroll up button */
#scroll-top { right: 0; bottom: 0; border-radius: 0; }
#scroll-top, #scroll-top:hover { background-color: transparent; }

/* Footer */
#footer-widgets .footer-box { text-align: center; }
#footer-widgets .social-widget .style-light li a, #footer-widgets .social-widget .style-dark li a,
#footer-widgets .social-widget .style-colored li a { background-color: #263036; color: #708e9f; border-color: #263036; width: 40px; height: 40px; line-height: 40px; }
#footer-widgets .social-widget .style-light li a:hover, #footer-widgets .social-widget .style-dark li a:hover,
#footer-widgets .social-widget .style-colored li a:hover { background-color: #0eb290; color: #fff !important; border-color: #0eb290 !important; }

/* Responsive */
@media (max-width: 767px) {
/* Center the buttons in the hero */
.elementor-element.hero-btn { text-align: center !important; }
/* Center elements on mobile */
