Hi there!
Sorry for the inconvenience!
I think you can try the following css into your custom CSS:
a {
color: chocolate !important;
}
body .sppb-btn.sppb-btn-default, body .btn.sppb-btn-default, body .sppb-btn.sppb-btn-primary, body .btn.sppb-btn-primary, body .sppb-btn.btn-primary, body .btn.btn-primary {
background: var(--gradient);
color: #fff;
}
.wimble-article-classic-view .article .wimble-article-author-wrap {
display:none;
}
First portion is for link color, second portion is for buttons, and the third one is to hide the posted by portion.
Blog pages doesn't have basic layout changing options. And customization support is prohibited here.
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.
