Showing bullet above horizontal carousel

I solved it editing custom-styles.css this way:

FIND CLASS:

.bx-wrapper ul li img

ADD THIS LINE:

margin-top:-20px !important;

RESULT:

.bx-wrapper ul li img {

max-height:100%;

max-width:100%;

display:inline-block;

margin-top:-20px !important;

}

Since this trick only places the logo image over the bullet to hide it, it only works with solid background images.

My theme uses the :before selector and adds a bullet with content: "?";
I solved it this way:

.wpb_text_column ul.kiwi-logo-carousel-opdrachtgevers li:before {
content: "" !important;
}
