Hello, Mohamed
“i want to change black logo to white logo if button actived https://prnt.sc/6jDCy_j35dEW” – to be able to give you an answer, we need to take a closer look at your site. Please contact us once you disable coming soon mode or provide temporary wp-admin access.
The next code can be used to change the styling of the back to top button:
.back-top {
color: red;
background-color: green;
}
.back-top svg path {
stroke: red;
}
Kind Regards,
