Each module in this spotlight-2 section is added with a custom class and template has style for these classes:

such as:

div#t4-spotlight-2 .bg-2 {
    background: #373693;
    color: #fff;
}

You can override this rule as you wish.

ludo974 4/ https://prnt.sc/C6oynoT9QPBV THIS IS THE SAME REQUEST AS CID ABOVE BUT THE TITLE BUTTONS please

There is css rule for this section title:

.section-title span {
    background: #e4f7ff;
    border-radius: 4px;
    color: #26b0eb;
    display: inline-block;
    padding: 8px 16px;
}

You can override the background / color to your desired color.

here I notice that I have texts that appear twice, how can I remove this error?

With the style of this module: Présentation you can disable the module title in backend to resolve this issue.

I updated for you, kindly check.

In that field, you can put a class name only.

You should add that css code into the custom CSS section in backend:

or add directly into this file: /templates/ja_vital/local/css/custom.css

I just added for you.
