It was something in the style I changed. Here is my code for that area. I just can't remember what I changed. I have done a lot of editing lately, lol.
<style>
#row {
float: left;
width: 100%;
border-spacing: 10px;
}
.boxtitlebg {
display: flex;
align-items: center;
justify-content: center;
}
.genblock {
display:table-cell;
width:32%;
height:100%;
border-radius: 8px;
padding-bottom:10px;
margin-bottom:10px;
}
#block1 {
background-color:#88f793;
}
#block2 {
background-color:#f7ec79;
}
#block3 {
background-color:#f9bd6d;
}
@media all and (max-width: 900px) {
.genblock {
display:block;
width:100%;
}
}
</style>
