SUPPORT Problem with CSS/Transparent avatar

Good night, I'm having a problem when I put an image behind the avatar.

By giving transparency to the image behind the avatar, my avatar also becomes transparent and I can't fix it...

I tried to implant the code:


 

Code:

opacity: 1;

to the "post-avatar" section to try to solve it but it's still the same... to the same at the bottom where you see the sent message counter is also transparent...




Does anyone know a solution? I pass the CSS code privately for help, many thanks and a cordial greeting!

P.D. I'm sorry if this issue wasn't here, I didn't know where to put it.

Solved: I'm solved writing in ".post-avatar" the code: "position: relative;"

Can close this thread.

Thanks all!
