Removing line on frontpage

Greetings! Customizing this wonderful template, does anyone have an idea how to remove the line between the bigger text and the smaller sub text?

Hello, try to use the following CSS code.

You can add CSS code in Customize → Additional CSS section.

.text-slider .maintitle::after {
    display: none;
}

Please feel free to ask any other questions that you might have.

Kind Regards, Roman.
