Also, I set a css code to make my rows become full width (I found it here through google)
.fl-builder #main > .wf-wrap {
width: auto;
padding: 0px;
}
It made my rows full width for all posts now, made through beaver builder. For example - see Geoscientist post.
I want my blog post width to remain like it is in https://aspirence.com/astronomer/ . How can I do that?
