I found this code very helpful and as you can see I added
/*Change background of headings */
background:#3f3f3f; opacity: 0.5;
Now that I am adding 0.5 of opacity ( the intention is to reduce only background opacity)
my whole post is 0.5 of opacity
Is there a way to reduce only background opacity and not the text and content fo the post?
you can see it here
thanks for your feedback!
