The carousel slider is a built-in feature which means you don’t have to do any setup nor installation to it. It will automatically shows up once you have your first blog post published.
If you do not wish to have it display on your blog, go to Appearance > Customize > Additional CSS > paste the following code in it.
.owl-carousel {
display: none !important;
}
If you’d rather have a regular full-width slider, please install any slider plugin and drag that slider widget to the “Slider area“. We recommend “Meta Slider” plugin.
