Two Code Questions: Changing Audio Block Colors and Changing Navigation Button Colors

Site URL: https://www.santisuk.org

Hi everyone,

I've posted this before for the navigation bar. However on my santisuk.org/silom page the buttons for the "branches" and "books" are white. I'd like to make them the same color blue as my custom navigation bar. Is there a way to do that for only the pages in the "silom" folder?

Secondly, for my santisuk.org/qrcode/bookone page I'd like to make the audio blocks on that set of pages match the purple/orange color scheme. Is there a way to do that for only those pages? Thanks!

Q1. Can you take screenshot buttons?

Q2. Add to Bookone page Settings > Advanced > Header

<style>
  .audio-block .player {
    background: red !important;
}
</style>
