Hello there!
Thanks for your query.
Please use the following code in your custom CSS:
.sp-pre-loader .circle-two>span, .sp-pre-loader .circle-two>span:before, .sp-pre-loader .circle-two>span:after{
border: 2px solid blue;}
.sp-pre-loader .circle-two>span{
border-left-color: transparent;}
.sp-pre-loader .circle-two>span:before{
border-right-color: transparent;}
.sp-pre-loader .circle-two>span:after{
border-bottom-color: transparent;}
Note: Path towards custom CSS: Extensions>Templates>Styles> Click on your current default template name then choose Template Options. Then find custom CSS within the custom code.
Hope this helps!
Best Regards
