Yes I inserted these codes in the custom.css file via the Helix framework as you can see on the first screenshot. After clearing the cache of the browser and that of Joomla, the problem is still there.
The page concerned: https://fedapisere.fr/toto
On the page https://fedapisere.fr/index.php?templateStyle=22&tmpl=comingsoon I want to get all the texts in white (not in the logo): how do I do this?
Thanks

Hello,
When I insert the custom CSS code via the Helix window https://postimg.cc/tZGgmMqS, sometimes it's OK and sometimes it's not OK. But I find that when I put the same code in the custom.css file and upload it with Filezilla, everything is OK. I would like to understand then what the Helix Custom CSS window is for.
Thanks
