No header transparency with rgba on iOS and ipadOS

Hi there, first: Sydney is great - except: there is no transparency with rgba on ipadOS and iOS for a header. I added the lines

.site-header {
background:rgba(0,0,0,.2);
}

to the custom CSS and it works perfect in windows in any browser but on the ipad the header has no transparency but instead is light grey to dark (varying with the 4th value). Any idea?
Thanks for any help - Georg

Hi Georg,

Older version of your web browser may not be able to recognize rgba. Please check its version and ensure you’re running the latest web browsers.

Stay safe.
Have an excellent day :slight_smile:
