+			the <a>flex container</a> is sized to the sum of the <a>max-content contributions</a> of its items

 			so that every flex item is <em>at least</em> the size of its <a>max-content contribution</a>,
 			but also has the correct ratio of its size to the size of the other items,
 			as determined by its flexibility).
 
 		For example, if a <a>flex container</a> has a single <a>flex item</a>
 		with ''flex-basis: 100px;'' but a max-content size of ''200px'',
-		then when the item is ''flex-grow: 0'', the flexbox (and flex item) is ''100px'' wide,
-		but when the item is ''flex-grow: 1'' or higher, the flexbox (and flex item) is ''200px'' wide.
+		then when the item is ''flex-grow: 0'', the <a>flex container</a> (and <a>flex item</a>) is ''100px'' wide,
+		but when the item is ''flex-grow: 1'' or higher, the <a>flex container</a> (and flex item) is ''200px'' wide.
 
 		There are several possible ways to make the overall behavior continuous between these two cases,
 		particularly when the sum of flexibilities on a line is between 0 and 1,
 		but all of them have drawbacks.
 		We chose one we feel has the least bad implications;
 		unfortunately, it "double-applies" the flexibility when the sum of the flexibilities is less than 1.
 		In the above example, if the item has ''flex-grow: .5'',
-		then the flexbox ends up ''150px'' wide,
+		then the <a>flex container</a> ends up ''150px'' wide,
 		but the item then sizes normally into that available space,
 		ending up ''125px'' wide.
