Add the css using the lang attribute so when you change the different language, the css is applied as per language.

[lang="en"] .navbarIcon {
    margin-left: 60%;
}

[lang="en"] .localiza {
    margin-left: 10%;
}

[lang="fr"] .navbarIcon {
    margin-left: 60%;
}

[lang="fr"] .localiza {
    margin-left: 10%;
}

You can find the lang code on your page when you inspect the element with your code in the HTML tag that shows the lang code.
