 * NOTICE the boxes are all the same size and fill up to the end of the container.
 * NOTICE that the text in the container does not control the size of the boxes.
 * No percentages were needed to make all the widths the same.

Different sized boxes By changing the number in "flex:#", you can change the width of individual boxes. Maybe you want "Research Help" to be twice a big as "Main Page" and "Get Involved" to be half the size of "Main Page. Here is the coding:   Main Page    Research Help    Wiki Help    Get Involved   Here is the result: Main Page  Research Help  Wiki Help  Get Involved
 * NOTICE that all that was necessary was to change the flex number in the boxes.

No sized boxes - flex:0 What if we do not want one or more of the boxes to change in size? Simply leave off "flex:#." Here is the coding:  Main Page Research Help Wiki Help Get Involved Here is the result: Main Page Research Help Wiki Help Get Involved
 * NOTICE that "flex:#" is missing from "Main Page" and "Get Involved."
 * NOTICE the end boxes are whatever size the browser gives them.

Here is the result:
