[Theme Horse Support Team]

Hi Jeremy,

To make the slider narrow login to your admin site Go to the Appearance > Customize > Ambition Theme Options > Custom CSS paste the following CSS code and Click on Save and Publish button:

.featured-slider .featured-image {
    padding: 10% 0;
}

And slider images are already stuck with the slider when you moves up and down this is a default built-in action.
If you are having issue with this please share your URL so that we can see the exact issue in you slider image.

Thank you for using our theme.
