Summary columns on mobile

Site URL: http://www.pennywatson.com.au/

Hello

I am setting up a new site using the Merida template. On the homepage I have different summaries for different sections with different blog posts.

This all looks perfect on desktop, but the column set-up is all messy on mobile. I want it to just be simple, an image above text. So one blog post taking up one mobile column.

The first two sections here have the problem...

Travel - I am happy to have the arrow slider, but I just want one column to show at once, not two

Eat & Drink - It has a small image to the left of the text, I just want the image to sit above the text and both to take up 100% of the single column.
