I found this related question that has a great solution where there is a two column design that stacks upon reaching the threshold of 320px. This is great; however, I'm curious if there's a way to use a width property in order to replicate this behavior of two columns stacking, but instead of the widths being constrained to 320px, they become width 100% after stacking on each other. The question can be found here: How to make html email responsive in gmail?
and the code can be found below
<!doctype html>
<html>
<body style="margin:0;">
<center>
<table border="0" cellpadding="0" cellspacing="0" height="100%" width="100%">
<!-- // 2-COLUMN SCAFFOLD [CENTERING, FLUID] -->
<tr>
<td align="center" height="100%" valign="top" width="100%">
<!--[if mso]>
<table align="center" border="0" cellspacing="0" cellpadding="0" width="660">

<td align="center" valign="top" width="660">
<![endif]-->
<table align="center" border="0" cellpadding="0" cellspacing="0" width="100%" style="max-width:660px;">
<tr>
<td align="center" valign="top" style="font-size:0;">
<!--// DEVELOPER NOTES:
1. Setting font-size:0; is necessary to ensure
that there is no extra spacing introduced
between the centering divs that wrap each
of the columns. //-->
<!--[if mso]>
<table align="center" border="0" cellspacing="0" cellpadding="0" width="660">

<td align="left" valign="top" width="330">
<![endif]-->
<div style="display:inline-block; max-width:50%; min-width:240px; vertical-align:top; width:100%;">
<!--// DEVELOPER NOTES:
1. To have each column center upon stacking,
wrap them in individual divs, set the same
max-width and width as the table within it,
and set display to inline-block; using
vertical-align is optional.
2. Setting min-width determines when the two
columns of this block will wrap; in this
case, when the total available width is
less than or equal to 480px. //-->

I recommend testing it out to see what I'm referring to. Any advice would be appreciated, thanks!
I believe this is what you are looking for. You can use media queries to target specific HTML elements with a class. I have given a class of FullWidth and when the screens size reaches 480 pixels, the blocks will be full width of the screen.
A few things to note:
Let me know if any questions
