Issue [Solved] Full width comment area border

Hi @kajo98,

Please watch this small video instruction: https://www.screencast.com/t/rAShqqRT

The CSS codes you should use: 

#wpdcom {
    max-width:  90%   !important;
}
#comments {
    max-width: 100%  !important;
}

Put the code in the "Custom CSS code" textarea, located in the Dashboard > wpDiscuz > Settings > Styles & Colors admin page.

The red-marked value can be changed as you like.  

Don't forget to delete the caches before checking.

Thank you so much, it helped!!

I can ask you one more time if it's not a problem. How can I save the change in my code from image 1 or create a CSS code from code similar to yours (images 2) because my code doesn't work

my css:

#comments {
margin-top: 2px;
padding-top: 30px;
border-top: 1px solid #f1f1f1;
}

And my second question. I can't find this section in my code (images 3), can you show me how to find it and change the color from white (#ffffff) to gray (#4c4c4c)

 Have a nice day:) 

Thank you very much. You have been so kind. Thanks
