Delete line in slider

Hi,
How do I remove the line
and how can make the two lines closer to each other?

Thank you

Hi,

Add this into: Customize > Additional CSS.

.text-slider .maintitle:after {
    background-color: transparent;
}
.text-slider .maintitle{
    padding-bottom: 5px;
}
.text-slider .subtitle {
    padding-top: 0;
}
