Most of the popular CSS frameworks that are available today offer some sort of grid system for us to use such that we can arrange our content in rows and columns. This is advantageous for a number of reasons, the least of which is not for aiding responsive design.
When it comes to WordPress, one of the most common elements that authors will use is the `more` tag.
Just as there are times where we may want to indicate that a class has (or doesn’t have) a `more` tag, we may also want to wrap the tag in a row with columns on either side of the tag.
This gives us flexibility in styling the tag not only by helping to place the text by using columns and/or offsets, but also by taking advantage of a grid in the context of responsive design.
