This will get rid of that specifically.
.page-template-page_front-page .entry-content #pg-3306-0 { border: 0; }
Thank you @paulwpxp
It works, but could you please help me understand how u figured it out, so I can learn for the future?
I used Chrome>Inspect Element but that part wasn’t showing up and I couldn’t figure out where to find it. How did you find it?
I would recommend to use FireFox.
@nikolai.lou , actually there’s nothing special here, I think the reason you couldn’t find it is just that you are too tired or too hurry so you just missed it — and this happens to everybody at some point.
When looking for box model related properties, sometimes it helps to look at the box model feature by clicking on the “Computed” or “Metrics” tab, so we could see the box along with width/height border/margin/padding in pixel number.
The #pg-3306-0 is what has the border, but it’s part of theme or plugin framework (panel grid) to build block of code so just to make sure that our code won’t effect this block if it’s used somewhere else, we limit our code to that part on that page only by using body class and entry content class.
