Banner Under Navigation menu needs a blank space??

Site URL: https://www.octaneworkholding.com/

I have added a blank text block above the banner image on my homepage because without the blank space any images are displaced.

The attached screenshot demonstrates this.

Is there a way to minimize the blank space block above this banner? 

You mean remove header overlap image?

If there is no blank section in between my banner and the Home, products etc. menu then when an image is uploaded as a banner it is not centered.

Adding a blank space in between makes the image format to fill the page correctly.  

The blank section seems to be required for the banner to function properly.  Is there a way to make this section a few pixels high?

Is there a way to inject code to shrink a section height like is above this banner?  Thanks
