Question

Finally, give .wildlife the property and value that forces any padding and border widths into its total width and height.

Do I just set all padding and border values to 0%?

It's looking for a css rule that will keep padding and borders within an elements total height/width, as opposed to adding padding and borders on top of the set width/height.

Notice these two boxes have the exact same stylings except for the box-sizing property.

The first one stays at 200px by 100px (the initial values set) and adds the padding and border to the inside of the box.

The second one starts out at 200px by 100px and adds on 20px of padding to each side and 7px of border width to each side, resulting in a box that is actually 254px by 154px

254px results from (200px + 20px padding on left + 20px padding on right + 7px border on left + 7px border on right)
154px results from (100px + 20px padding on top + 20px padding on bottom + 7px border on top + 7px border on bottom)

Hey Luc Sengers , What the question is referring to here is setting

.wildlife {
    box-sizing: border-box;
}

This is touching on the CSS box model. Which is essentially a box that wraps around HTML elements, and it consists of: margins, borders, padding, and the actual content.

This can cause some people to trip up because say you have 2 elements you want to take up the screen so you float them and set them to 50% . This will work, but now lets say you have a 1px border on one of the elements. Now that is not truly 50% it it 50% + 1px so it will no longer fit. This is where "border-box" comes into play, It takes borders and padding and automatically factors them into the width so we dont have to be compensating for borders and paddings in our css.

Hope that Helps Cheers, Vince
