[נפתר] Custom styles for transferring languages

Background of the issue:
I display the language switcher in the header. I used the shortcode [wpml_language_selector_footer] to display it. Disabled it in the footer. Adding custom styles.

Symptoms:
The styles are not applied correctly. When switching languages, they stop working.

Questions:
Why are my custom styles not applied correctly when switching languages?
How can I ensure that the custom styles for the language switcher remain consistent across language switches?
