Vertical alignment

 * Back in lesson 4, you were introduced to lists. If the number of items in the list is short, listing them in a single column is ok.
 * But what if you have, say 100 items. Do you have a single column with a 100 items listed?  That takes up a lot of space as you can readily visualize.
 * A better way to display 100 items is to have, say, four columns of 25 each. Takes up a lot less space and might even eliminate scrolling to see all the items.
 * Here is where tables come into play.

Create a table with only one row

 * Create a table with only one row and with the number of cells to equal the number of columns you want to create.
 * If you have 16 items, you might have four column with 4 items in each.


 * Here is an example of the counties in Naveda.

How many columns?

 * Because many of our patrons are viewing the Wiki with pads or smart phones, try to limit the number of columns to no more than four.
 * You can, of course, have two or three columns if that works better.

Uneven column lengths

 * When creating these lists in columns, you will rarely have columns where the last column has the same number of items as the preceding columns.
 * If the last columns does have fewer items, you will find these items in the middle of the cell and not at the top as in the preceding columns.
 * Here is an example of the list of counties from the state of Vermont below.
 * Notice the counties in the last column is in the middle of the column.
 * Again the reason for this, is that the default for entering material in a cell is to place it in the middle and not at the top.
 * If all your cells have the material at the top even with unequal material in each, you will see that the cells are of different widths. However, if the cells are of the same width, then the material could be in the middle of one of the cells as in the above example.

Vertical align

 * In order to keep the material in each cell at the top of the cell, lets introduce another attribute called: vertical-align:top
 * We will add this attribute to the cell tag:
 * Here is what the table looks like now:
 * Note, we have added padding on the right to give additional space between columns.
 * This is the format we want when displaying long list of items on our pages in the Wiki. Here is an example of what we mean: Missouri.

Keep columns even in length

 * When creating these lists in columns, keep the first, second or third columns of equal length. The remainder are at the top in the last column as in our example above.

Vertical alignment
When we place some text in a div or paragraph tag that is taller than the text we are placing, the text will appear at the top of the container. What if we want the text in the middle of the container? To do that, we use the combination of text-align and line-height attributes.  This text is in the middle This text is in the middle.
 * Let's make a container or box with a div tag that is 50px in height with a line of text.
 * Next we need to combine the text-align with line-height.
 * If we set the height of the line-height to 50 pixels, the text will be in the middle of the container. Here is the coding:
