How to remove text transparency on the Hero text

Hello, I'm using the Quark theme and I can't find anywhere where I could remove the transparency on the text of the header.
For now, the text is white but not fully white : https://parcoursvelo.be/

The text become transparent as soon as i add a hero image. It is not due to a class.

It worked thank you very much!

@Delo, That is nice to know, but the community would like to know what you've changed and how and where you made the change.

It is a two-way street: You ask for a favour and you return a favour...

In theme.min.css I changed the hero.text-light h2 rgba(255, 255, 255, .8) to (255, 255, 255, 1) to make it opaque.

@Delo,

In theme.min.css I changed

Yes, I've noticed that looking at your site...

1. It is not a good idea to edit a generated *.min.css file.
   • Edit the original *.scss files instead and recompile.
   • Or, use custom.css instead.
2. You are in for a surprise when a new release of Quark arrives: All you changes will be gone...
   Use an inherited/child theme and use the /user/mytheme/css/custom.css in your own theme to make changes.

Thank you for letting me know i had no idea these could interfere with the updates.
Here's what i added to custom.css :

.hero.text-light h2 {
    color: rgba(255,255,255,1) !important;
}

@Delo, Still 2 issues:

• /user/themes/quark/css/custom.css is being included twice.
  Not sure what you have done in Twig templates.
• You are not using a child/inheriting theme. All changes will be lost in due time...
  Also all changes in custom.css.

Sorry I don't know what's a child theme
I'll be reading about it
