This members-only tutorial provides the steps to arrange posts output by Oxygen's Easy Posts component in a custom layout using CSS Grid's grid-template-areas.
Post categories (linking to their category archives) will be positioned near the top left of posts' featured images.
The entire image will be set to be clickable to the post's permalink.
From 767px and below, we shall set the posts to appear one below the other.
Step 1
Since the maximum width taken up by the images for any given viewport is close to 800px (767px - 40px of padding = 727px to be exact), let's define a custom image size of say, 800px by 800px and display the images in this size.
