If you’re running a child theme you’ll put it in your child’s style.css. If not (if you don’t know what a child theme is you probably aren’t running one 🙂 ) put it at the end of your template’s style.css
You can add a hidden visibility and height:
#post-author {
background: url(http://www.dcgaengineers.com/wp-content/themes/theme1449/style.css) 0% 0% repeat;
overflow: hidden;
padding: 20px;
margin-bottom: 2em;
visibility:hidden
height:0px;
}
That takes out all your author info section.
If you want to only take out the “written by” line you’ll have to search through your template’s files to find that field and take it out.
Hope that helps!
@emberjd- mercime is saying there is no “Important Information” page, no link for it and no text for it.
