Overwriting CSS in spacer block

Site URL: https://addanote.co.uk/pricing-1

I've got 2 sections and the same CSS applied to both because they have the same class however, is there a way to only apply the style to the middle instance in the second section. I've tried changing the class in DevTools and this is the outcome I want however, this isn't possible in the site. 

Is there a solution for this? Or can someone give me closure and tell me that it isn't possible.

Use nth-child() selector.

You can target middle column with this CSS

div#page-6241a52b9b9b6e18bb394e59 .span-4:nth-child(2) {
    background-color: #EDF4DD;
}
