[Resolved] I use divi. My language switcher is before top-menu; dropdown with flag en language. In the dropdown...

Problem:
If you're using the Divi theme and notice an empty space before the flag and language in your language switcher dropdown menu, it might be due to the Critical CSS feature altering CSS priorities or broad custom CSS selectors affecting the dropdown.
Solution:
We recommend adding the following CSS code to your site to correct this issue. You can add this code via WP Dashboard > Appearance > Customize > Additional CSS or through any other CSS section provided by the Divi theme:

#et-secondary-nav li>ul.sub-menu {<br />    width: 75px;<br />}<br /><br />#et-secondary-nav li>ul.sub-menu li {<br />    text-align: center;<br />}

This CSS should help align the elements properly and remove the unwanted space.
