Stop resizing blog post spacing on Blog Page

I am trying to have the same, consistent spacing for my Blog page on desktop and mobile. 

I would like a little space beneath the Blog title, and large space beneath the rows — the way I have it on desktop. Please see the screenshot; the desired spacing is in green.

On 767px and below, for some reason, the spacing changes. I don't want the spacing to change on mobile. I want it to be these same as desktop. 

Can someone help?

See the image attached.

You can may need to open the inspect element panel and notice its responsiveness. 

I see your screenshot has 5 items, so you can see space, here shows 4 items only
