Font Issue. Huge font wont change

How do you change the font on the Slider heading / text? I’ve went through all the font options but still remains huge.

Can someone please assist?

Hi,

You can use this CSS code below to adjust the font size:

.text-slider .maintitle {
    font-size: 44px;
}
.text-slider .subtitle {
    font-size: 20px;
}

Put the code into Customize > additional CSS.

And because the subtitle text is too much, it will not displaying good in mobile screen.
