In the How to Make Website video Nick talks about setting up the image gallery using a css-rule containing the float property with the value left. He gives the list elements a width of 45 % (times 2 elements equals to 90% total width). After that he continues to set the margin for the list elements to 2,5%. His css declaration is " margin: 2,5% ".
Why does this only set the margin for left and right? Why wouldnt that set the margin for all four sides of the element? Previously we learnt that if you want to set a margin for example for the top and the bottom, you would declare(e.g. margin: 10px 0px;) would set set the margin-top and margin-bottom to 10px, while left and right would remain at 0px. Why doesnt he declare "margin: 0% 2,5%;" in his css-rule to only affect the left and the right of the working elements?

The vertical components of the margin setting are just not mentioned.
