Now let's look at one of the images in our HTML file. We can see the octopus image is inside of a container. The container is the figure element:
<figure> <img src="images/octopus-icon.png" alt="Octopus"></figure>
The figure element doesn't have a width defined, but it's a block-level element that takes up the entire width of its container. So we could think of the figure width as 100%. It's inside of the column div:
<div class="column"> <figure> <img src="images/octopus-icon.png" alt="Octopus"> </figure> <h2>The Octopus</h2> <p>...</p> <a href="#" class="button">Tenticals »</a></div>
If we look in our CSS column, we see the column width is 31.25%:
/****************3 columns****************/.column ...
