Buttons, text on slider

Hi

Please share your site link, so that have a better idea

Hi

you can make this div display :none
.slider-content-wrap{display:none}

it will be better if you install this plugin to change css https://wordpress.org/plugins/simple-custom-css/

because changes made directly to theme css file will be lost when theme is updated.

Hi

yes to show it only on the first slider you can add this css after the above one
.owl-item:first-child .slider-content-wrap{display:block;}
