I would like to – in the top right corner – display two adjacent links/buttons.
When the user is not logged in, it must display: Register + Log inWhen the user is logged in, it must display: Hi Username + Log out
I did it for you! https://prnt.sc/rvxxbf https://prnt.sc/rvxxsg
Thank you so much.
Where did you change it?
I edited it using the child theme.
Here, I added child theme file components / topbar.php https://prnt.sc/rwi1e8 + some CSS code in style.css https://prnt.sc/rwi1uq
How do i increase the logo size for mobile?
I have increased the size of the mobile logo for you. Because your logo is long, it is difficult to be bigger. Increasing the size of the logo further damages the layout header.
This code will help you do it:
max-width: 120px !important;
