Finally found a great way to equalize the heights of the posts within the Divi blog module so that they don't look so messy. The code came from Divi-Sensei.com but I'm copy/pasting below in case they ever take that post down. Complete credit goes to them for this one.
/*Equalize Blog Columns*/
.bloggrid .et_pb_salvattore_content {
display: -webkit-box;
display: -ms-flexbox;
display: flex;
}
.bloggrid article {
margin-bottom: 20px !important;
-webkit-box-flex: 1;
-ms-flex: 1 0 auto;
flex: 1 0 auto;
display: -webkit-box;
display: -ms-flexbox;
display: flex;
-webkit-box-orient: vertical;
-webkit-box-direction: normal;
-ms-flex-direction: column;
flex-direction: column;
}
.bloggrid .post-content {
-webkit-box-flex: 1;
-ms-flex: 1 0 auto;
flex: 1 0 auto;
display: -webkit-box;
display: -ms-flexbox;
display: flex;
-webkit-box-orient: vertical;
-webkit-box-direction: normal;
-ms-flex-direction: column;
flex-direction: column;
-webkit-box-pack: justify;
-ms-flex-pack: justify;
justify-content: space-between;
}
.bloggrid .column {
margin-bottom: 20px !important;
display: -webkit-box;
display: -ms-flexbox;
display: flex;
-webkit-box-orient: vertical;
-webkit-box-direction: normal;
-ms-flex-direction: column;
flex-direction: column;
}
