Hi Maryanne,

The slider can be edited by going to the "Pages" tab and edit the homepage. Below the page builder you'll find the slider field to edit your slides.

In the following link you can find a screenshot of the slider below:

You're welcome.

To reduce the height of the slider you can use the following CSS code. This code can be added to the textarea under Appearance -> Customize -> Additional CSS:

.jumbotron .carousel-inner > .item > img {
    object-fit: cover;
}
/* Mobile Screens */
@media (max-width:768px) {
    .jumbotron .carousel-inner > .item > img {
        height: 300px;
    }
}
/* Tablet Screens */
@media (min-width:769px) and (max-width:992px) {
    .jumbotron .carousel-inner > .item > img {
        height: 400px;
    }
}
/* Desktop Screens */
@media (min-width:993px) {
    .jumbotron .carousel-inner > .item > img {
        height: 500px;
    }
}

The 300px height can be changed for mobile screens.

The 400px height can be changed for tablet screens

And the 500px height can be changed for desktop screens.

Hope this helps.

You can change the font color by replacing that top heading text with the following line:

<font color="red">This will be the heading text</font>

The value red can be changed to your own needs.
