'Why Are My Images in the Three-Columns Row Not Lining Up Horiztonally?

Trying to build up my first actual email template and I'm having some issues with the three-columns images lining up vertically above and below each other, not horizontally with each taking up 200px of 600px like I'm aiming for. I've combed through the code 3x now and have not found the issue, as at this point I'm following along with a tutorial and watching his work perfectly. What obvious thing am I missing? I apologize for the sloppy CSS formatting in advance, I'm trying to reduce the line count a bit since every line will need quotes around it for Yogmail. Thank you!

Edit: Just added the entire template so you can see that it's not till three-columns that the email template breaks, and from there even the footer or copy and pasted borders are stuck in the center. I seem to be having a similar problem with anything I build into this document after the three-columns section, but not before. I'm guessing maybe they're pulling CSS from a class I'm not intending it to? Everything above the section I posted works as intended, while everything below it is stuck in the center without the ability to display horizontally.

CSS:

<style>
body     {background-color: #cccccc;margin: 0;}
h1       {color: black;font-size: 150%;text-align: center;}
p        {color: black}
table    {border-spacing: 0;}
td       {padding: 0;}
img      {border: 0;}
.wrapper {width: 100%;table-layout: fixed;background-color: #cccccc;padding-bottom: 60px;}
.main    {background-color: #ffffff;margin: 0 auto;width: 100%;max-width: 600px;border-spacing: 0;font-family: poppins;color: #26a69a}
.two-columns {text-align: center;font-size: 0;}
.two-columns .column {width: 100%;max-width: 300px;display: inline-block;vertical-align: top;}
.button {background-color: #26a69a;color: #ffffff;text-decoration: none;padding: 12px 20px;font-weight: bold;border-radius: 10px;}
.three-columns {text-align: center;font-size: 0;padding: 35px 0 20px;}
.three-columns .column {width: 100%;max-width: 200px;display: inline-block;vertical-align: top;}
.three-columns .padding {padding: 15px}
.three-columns .content {font-size: 15px;line-height: 20px;}
