Hello Tyler,
Greetings of the Day!
1) To remove sidebar, please go to Apperence >> Customize >> Theme Options >> Layout Options and select “No Sidebar” under “Global Layout”.
2) If you are asking about slider then it is 3rd party revolution slider. If you want, you can purchase it and use it to create sliders as per your requirement. After creating slider, Please go to Appearance >> Featured Slider Options >> Slider On/Off >>
Select “Using Shortcodes” under “Slider Type” option and paste that code that you have received after creating a slider. Please, let us know in case you are asking about something else.
Feel free to get in touch in case of other queries.
Thanks and Regards,
Team ProDesigns
