My home page is a two column layout for blog post. I used the following code to create a border around each post on the home page that works well:
border: 1px solid #DDD;
However, when I click on an individual post, I don’t want the border to appear on each single post page.
Also, I don’t want border to appear when view on mobile.
What code can I use to remove border on individual post page and mobile view?
