Toolbar button background color always white

[MarcoFFSiciliano]

Hello,
i try to set the background color of the toolbar. The background color of the zoom dropdown and page number line-edit do not change / remain white. The 'normal' background changes correctly.
Any ideas how to do this?

You should be able to fix this by adding a CSS rule like this in the global styles.(s)css file:

html ngx-extended-pdf-viewer .html .toolbarField,
html ngx-extended-pdf-viewer select {
   background-color: #fff !important;
}
