Change tab close background

Hi, is there a way to change tab close background to something like this;

Right now, its like this;

Sorry for the trouble.

Unfortunately the default style of Vim is hardcoded to always draw a X character.
Vim itself does not support a simple customization of the tabline other than overriding the function that renders it which is a bad idea to do so.

Vim's default tabline style with Nord colors.

To learn how to configure the tabline, the :help setting-tabline documents the tabline option which specifies what the line with tab pages labels looks like.

Looking on your screenshots I guess you're using the lightline-vim or vim-airline plugin that both support Vim's tabline option like both project descriptions also state:

[...] statusline/tabline plugin for Vim [...]

Both plugins also provide documentations like e.g. :help g:lightline.tabline that describes how to configure lightline.vim for the tabline component.
This way you can customize the content and ordering of the tabline:

set showtabline=2
let g:lightline.tabline = {
            \ 'left': [ [ 'tabs' ] ],
            \ 'right': [ [ 'close'] ] }

Tabline style provided by the lightline.vim plugin using the Nord color theme.

In order to style the close button like on your first screenshot, the tabline.right map of Nord's bundled lightline.vim color theme must be adjusted, e.g. to use the same style like for the active tab:

-let s:p.tabline.right = [ [ s:nord5, s:nord3 ] ]
+let s:p.tabline.right = [ [ s:nord1, s:nord8 ] ]

Adjusted Nord lightline.vim color theme.

One way to do this is to refactor Nord's lightline.vim color theme to allow users to customize and override the default styles like already proposed in #124 for the vim-airline plugin.

Thanks for the infos 🙂

Should we expect this in release?

Unlikely, since this is related to airline/lightline, and not to nord.
