Make the header 50% width and transparent over a split section.

Hi,

I'm mocking up a template for a cosmetics brand.  I am using split sections and id like the header to only go across the left side section. 50% width works for this but then i need it to be transparent over the background image section.  The main issue is when i do the transparent header it only starts to show on scroll.  The other issue i have is that i would like the nav links to display as a block at the bottom left side of the page.  also with a transparent background.   I have tried making the header 50% width and 100Vh height. I doesn't work.  

Any advice would be greatly appreciated. 

this is what i mean by the nav links - but i would like the logo just on left hand side.

this is the code i have that's not working. It just shoves it all down the page.... 

.header {
  width:50%;
  height:100vh;
  background-color:transparent !important;
  z-index: 99999;
  position:fixed;
  top: 0;
  left: 0;
  
  	display: flex;
	flex-direction: column;
	align-items: left;
	justify-content: space-between;
}

It looks like you have figured it out. Do you still need help?

no i haven't figured it out at all apart from the 50% width! Still need to make it fully transparent and the links at the bottom left of page...
