Need help aligning these boxes

Site URL: https://elephant-raspberry-f4jz.squarespace.com/

hey guys!

I'm just trying to align these "service" boxes on the same line horizontally. I'm not sure why it's happening. It displays fine on code block:  https://codepen.io/annamakesmagic/pen/ZEoOMVq

but when added to the block with the div labelled "lead"  ("Our core service is...") the alignment gets weird. 

Can someone please show me how I can change my code (below) to fix it? Thanks! 

<style> 
  .lead {
    display: block;
    padding-top: 3%;
    width: 100%;

Hi @AnnaNeedsHelp, it looks like from your live site that you've fixed the alignment (as far as I can see), is this still something that you need addressing?

You code looks pretty good, but there's maybe a typo for the .service h4 top margin of 12rem, should be 1.2rem, maybe? You may want to adjust the padding around the blocks so that they are a bit more responsive on medium sized screens, using a vw value rather than a px. There's also a 50% max width on the blocks that you may want to remove at your mobile breakpoint of 900px (it looks odd at screen sizes around 800px wide).
