Hello,
I am making my website on wordpress.com plateform. So far I managed nearly good enough but this time I give up on my problem I need help.
I have set up a navigation menu transparent that lets the cover being seen. The mobile version collapses the menu but there's a white screen instead of transparency. I looked on internet, I looked on youtube, I tried to tweak the settings, the patterns, the templates with no result.
I do not want to add any pluggin for that matter.
I would like to keep the menu in white as I use black and grey in the rest of the website. The menu and the button on the right are sticky.
I could add CSS but I'm a total noob in that.
Here screenshots of my problem.
Thank you for your kind help.

Is your mobile menu inheriting the font colors? i.e. white font color on a white background?
