Hi David,
Just to be clear, you are trying to add 2 columns to the content area using Classic editor?
Well, that will require custom HTML and CSS I believe.
As it’s not theme related, we can’t really offer a full solution for this, unfortunately.
The structure can be something like this:
<div class="custom-columns">
<div class="custom-column-1">column 1</div>
<div class="custom-column-2">column 2</div>
</div>
Then you can use CSS like this to set the column widths:
.custom-columns {
display: flex;
}
.custom-column-1 {
width: 40%;
}
.custom-column-2 {
width: 60%;
}
