1,036 PointsI dont understand what makes the images stack in two columns.
How does Float: Left make the images stack? I'm not understanding the explanation given in the video. We have 5 images, when we float them left they stack three then two?
Why don't they all float to the left?

Imagine by default all items are stacked top-to-bottom of one another. . .

. . . float left is telling the items to rest side-by-side one another starting from the left. . .

. . . if there is no more screen space to take up items will go below but still float to the left side of the page . . .

1,036 PointsThanks Curtis for your explanation. I think the video could have done with some more in depth explanation of floats. After reading your answer I understand it now.
In the context of the video example though, what is the parent element that the items are floating inside? is it the wrapper div?
Thanks again!

If you look at the code, Nick's
#gallery li {
float: left;
width: 45%;
margin: 2.5%
}
says, we have margin 2.5% of the page width all around. Well, width of the child is 45% + 2.5% +2.5% = 50%. And 50% +50% equal 100%, so two children elements are exactly as wide as the parent, so two sit side by side, the remaining floating children fall down to the next line and repeat.
If the total of the children was any more than 100%, only one child would be on each line, and if it was less, you'd still only have two children per line until a 3rd child could fully be contained within the width of the parent.

1,036 PointsIs it because, if a third li was to float left of the second li, it would break out of its parent element and therefore falls below?
