<p>
The blue borders should coincide with light blue squares, like this:
<span style="display: inline-block; background-color: lightblue; border: solid dodgerblue; width: 19px; height: 19px;"></span>.
There should be none of this:
<span style="display: inline-block; background-color: lightblue; width: 25px; height: 25px;"></span>
or this:
<span style="display: inline-block; border: solid dodgerblue; width: 19px; height: 19px;"></span>.
</p>
<div class="columns" id="t1">
<br>x y z
</div>
<div class="columns">
<br><span id="t2">x y z</span>
</div>
<div class="columns">
<br><div id="t3">x y z</div>

<div class="columns">

Except here, where the blue border should be around the bigger slice of the blue square, on the right.
