Try this
.slider-wrapper.secondary-slider-wrapper.my-20 {
position: relative;
display: grid;
grid-template-columns: auto auto auto;
grid-template-columns: repeat(3, 2fr);
grid-template-rows: 135px 135px;
grid-gap: 0px;
}
If you have more rows, increase the grid-templates-rows: 135px 135px 135px;
Note: This will help you to get 3 columns
Didn't try 4, sorry
