The sample is a blog with a masonry layout with four columns.
The Muse file is set up like below:
In Muse, you can open the Blog Container (Main Widget) and select how many columns you want to appear on each breakpoint.
The blog posts on the main page only show a preview of the blog post. In the blog settings, you can specify the amount of characters that will show up.
The latest posts widget loads the titles and dates of the latest five posts.
The blog widget also allows you to add a tag cloud. You can choose to sort tags by (1) randomly, (2) frequency, or (3) alphabetically. You can specify the minimum and maximum font sizes so that the most frequently used tags are the largest and the least frequently used tags are the smallest. These settings can be changed in Muse by opening the Tag Cloud Widget Options.
