2.5% margin to = 10%?
How does 2.5% margin equal 5% for each of the two floated images when he only considered the left and right margins? Doesn't margin: 2.5% mean 2.5% top, bottom, left side, right side? That would give a total of 10% for each image
That's a good question.
The reason is because you're using a float.
Go back to your main.css. Try typing out "float:" in your CSS and you will set a drop down list with these options to choose from: none, left, right, inherit. There are no options for top or bottom, so top and bottom will not change when using the float.
The width must be specified because with the float property, the objects are being taken out of the normal flow of the document. Since the float only goes by left and right, the margin you specify tells the browser to apply the margins only to the left and right.
