You should ask in your theme’s support forum.
Centered text is difficult to read. Centering a block element with left text is different than centering text elements. Text elements use text-align:center, within the block element. Block elements use margins or table display or flex or grid, etc. determined by your theme.
try centering the block element with left text, using:
.single div#primary { margin: auto; float: none; }
in ‘Additonal CSS’
and then ask those theme related questions in https://wordpress.org/support/theme/viral-news
Thank you @alchymyth, your solution work great. I’m grateful.
