Slider Image Dimensions and Removing Margins in Makeup Theme

Hello

I am currently working on my website using the MAKEUP prebuilt theme, and I have encountered a few issues related to the slider image dimensions and unwanted margins. I would appreciate your guidance on the following:

– Adjusting Image Dimensions in the Slider

I would like to know if there is a way to control the dimensions of the image within the slider without manually resizing it in Photoshop.
So far, the only way I have managed to make it fit properly is by adjusting the image dimensions in Photoshop and testing different sizes.
Is there a built-in option or setting that allows me to scale or crop images directly within the theme’s slider settings?
– Removing Margins in the Makeup Prebuilt Theme

I have noticed that my slider has margins on both sides (as shown in the attached screenshot).
I was able to remove the top margin by repositioning the element in Elementor, but I would like to know if there is a more efficient method to make the image cover the entire homepage while still allowing me to control the transparency of the menu if needed.
Could you please guide me on how to completely eliminate the margins and achieve a full-width layout?
I appreciate your help and apologize for the inconvenience. Looking forward to your response!
