HOMEPAGE

My portfolio website relies heavily on carousels. The home page has a full-screen carousel at the top. The first issue is that the close "X " icon appears on the right side of the "About" menu:
www.marcal.net

When scrolling down to see the other project carousels, the top "X" icon disappears.

My first question is whether it would be possible to disable the "X" icon when loading the homepage. Same issue in mobile browsers / iPhone.

PROJECT CAROUSELS

Another topic is, for example, when I click on any of the home page carousels below, it loads the project with the option to close the project by clicking the "X" icon at the top again. This is good, as closing the project makes the homepage visible again.

The issue is whether it would be possible to have the "X" icon aligned vertically with the menu "Index About X".

The issue is worse on mobile, where the "X" icon is placed disaligned over the "About" (tested in iPhone Pro 15). (Screenshot attached below)

Moreover if there are other option to place the "X" icon in other places, for example, leave the menu only to "Index About" and then place the "X" icon right below.

NEGATIVE CONTRAST

Last question related to the "X" icon, and for extension the whole website logo, menu and "X" icon.

Some projects on my website have a white background, others have a black background, and others have a colour background. The issue is that when any project has a black background, the website logo, menu, and "X" icon logically disappear, only to become visible when an image scrolls down underneath. (Screenshot attached below)

Black background example:

White background example:

My last question is: is there any way for mainly the "X" icon, and if possible, for the website logo and the menu to have a negative overlay effect, so that it is always in the negative colour of anything it has underneath.

Many thanks,

Marçal
