 To make container queries even more useful, you can use container-based unit values as well. The following table shows the possible container unit values and how they correspond to a container’s size:
 
-<table><thead><tr><th>unit</th><th>relative to</th></tr></thead><tbody><tr><td><code>qw</code></td><td>1% of a query container’s width</td></tr><tr><td><code>qh</code></td><td>1% of a query container’s height</td></tr><tr><td><code>qi</code></td><td>1% of a query container’s inline size</td></tr><tr><td><code>qb</code></td><td>1% of a query container’s block size</td></tr><tr><td><code>qmin</code></td><td>The smaller value of qi or qb</td></tr><tr><td><code>qmax</code></td><td>The larger value of qi or qb</td></tr></tbody></table>

 One example for how you would use container-based units is responsive typography. The viewport-based units (such as `vh`, `vb`, `vw`, and `vi`) can be used to size any element on the screen.
